Poland during the rule of Bolesław III Wrymouth

Bolesław III Wrymouth (also known as Bolesław III the Wry-mouthed, Template:Lang-pl) (20 August 1086 – 28 October 1138) was Prince of Lesser Poland, Silesia and Sandomierz during 1102-1107 and over all Poland during 1107-1138. He was the only child of Prince Władysław I Herman and his first wife Judith, daughter of Vratislaus II of Bohemia.

Bolesław began to rule in the 1090s decade of the 11th century, when the central government in Poland was significantly weakened. Władysław I Herman fell into political dependence of the Count palatine Sieciech, who became in the real ruler of the country. Boleslaw and his half-brother Zbigniew after several years of fighting in 1101 finally expelled Sieciech from the country backed by their father. After the death of Władysław I Herman in 1102 were created two independent states to Bolesław and Zbigniew.

The pursuit of Bolesław to gain Pomerania caused an armed conflict between the brothers, following which Zbigniew had to flee the country and seek military help from Germany. Bolesław effectively stopped the intervention of the German King Henry V in 1109 and punished Zbigniew blinding him. This action caused outrage among supporters of Zbigniew, resulting in a political crisis in Poland. Bolesław gained again the favor of his subjects with public penance, and made a pilgrimage to the monastery of his patron, Saint Giles, in Hungary.

Bolesław, like Bolesław II the Bold, based his foreign policy on maintaining good relations with neighboring Hungary and Kievan Rus, with whom he forged strong links through marriage and military cooperation in order to break the political dependence of Germany and his vassal, the King of Bohemia, who in moments of weakness Polish policy was forced to pay tribute in Silesia. This alliances have allowed him to effectively defend the country from Henry V's invasion in 1109. Several years later, Bolesław skillfully took advantage from the dynastic disputes in Bohemia to ensure peace on the border of the south-west.

In the second half of his rule, Bolesław devoted to the conquest of Pomerania. In 1113 he conquer the northern strongholds along Noteć, strengthened the border with the Pomeranians. In subsequent years, he took steps toward the conquest of Pomerania. The resolution of the conflict with the Holy Roman Empire allowed Bolesław the incorporation of Gdańsk Pomerania Gdansk and the subordination of Western Pomerania. The military expeditions carried out in three stages, ended in the 1120s with a military and political success. Integration of the newly annexed lands enabled to Bolesław the process of the conversion of Pomerania, and the construction in these areas of Churchs. Bishop Otto of Bamberg from 1123 onward confirmed the Christianization.

In the 1130s Bolesław participed in the dynastic dispute in Hungary. After an unexpected defeat, was forced to made an agreement with Germany. In the Congress of Merseburg of 1135, was addresses the issue of Pomerania, Silesia (probably also Poland) sovereignty and then the supremacy of the Archbishopric of Magdeburg over the Polish Church.

Bolesław was married twice. His first marriage with the Kievan princess Zbyslava, gave him an excuse to intervene militarily in the internal affairs of Russia. After her death, Bolesław married to a German noblewoman, Salomea of Berg, which in some way was the cause of changes in Polish foreign policy: in the second half of his rule, the Prince sought to restore diplomatic relations with his western neighbor. His last, and perhaps the most momentous act, was his will and testament known as "The Succession Statute" in which he divided the country among his sons, leading to almost 200 years of feudal fragmentation of the Polish Kingdom.

Bolesław III Wrymouth has been recognized by historiography as a symbol of Polish political aspirations until well into 19th century. He also upheld the independence of the Polish archbishopric of Gniezno, despite a temporary failure in the 1130s. Despite undoubted successes, he committed serious political errors, most notably against Zbigniew of Poland, his half-brother. The crime against Zbigniew and his penance for it show Bolesław’s great ambition as well as his ability to find political compromise.

Childhood

Situacion of Poland during the 1080's

In 1086 the coronation of Vratislav II as King of Bohemia, and his alignment with László I, King of Hungary, threatened the position of the Polish ruler, Prince Władysław I Herman. Therefore that same year Władysław I was forced to recall from Hungarian banishment the only son of Bolesław II the Bold and a rightful heir to the Polish throne, Mieszko Bolesławowic. Upon his return young Bolesławowic accepted the over-lordship of his uncle and gave up his hereditary claim to the crown of Poland in exchange for becoming first in line to succeed him. In return, Władysław I Herman granted his nephew the district of Kraków. The situation was further complicated for Władysław I Herman by a lack of a legitimate male heir, as his first-born son Zbigniew came from a union not recognized by the church. With the return of Mieszko Bolesławowic to Poland, Władysław I normalized his relations with the kingdom of Hungary as well as Kievan Rus (the marriage of Mieszko Bolesławowic to a Kievan princess was arranged in 1088). These actions allowed Herman to strengthen his authority and alleviate further tensions in international affairs.

Birth of Bolesław

The lack of a legitimate heir, however, remained a concern for Władysław I and in 1085 he and his wife Judith of Bohemia sent rich gifts, among which was a life size statue of a child made of gold, to the Benedictine Sanctuary of Saint Giles in Saint-Gilles, Provance begging for offspring. The Polish envoys were led by the personal chaplain of Duchess Judith, Piotr.

The date of birth of Bolesław is closely linked with the death of his mother Judith. This fact is evidenced by contemporary sources:

• Gallus Anonymus in the Cronicae et gesta ducum sive principum Polonorum reported that Duchess Judith gave birth to Bolesław on the day of King Saint Stephen of Hungary (whose feast since the 11th century was celebrated on 20 August). However, the Duchess' health never recovered from childbirth and died on the night of Nativity (i.e. 24–25 December). Gallus didn't put in his chronicle any date year.

• Cosmas of Prague wrote in Latin in his Chronica Boëmorum ("Chronicle of Bohemians") that Bolesław was born three days before the death of Judith, who died in VIII Calends of January (25 December) of the year 1085.

• The Kalendarz krakowski said that Duchess Judith died on 24 December 1086, and only indicated that the birth of Bolesław was in the same year.

• The Obituary of the Abbey of Saint-Gilles reported the death of Judith on 24 December 1086.

• The Rocznik kapituły krakowskiej (closely related to the Kalendarz krakowski) placed the death of Judith on 24 December 1086.

Historian August Bielowski established Bolesław's birth on 26 December 1085 and the death of his mother two days later, on 28 December. According to him Gallus Anonymus committed two errors. First, instead of the Sunday after the Nativity of the Lord wrote incorrectly in the Sunday of the Nativity. Secondly, he mistaken the day of Saint Stephen (26 December) with the festivities of King Stephen of Hungary (20 August). Both corrections lead to the birth date of Bolesław on 26 December. This theory was supported by the fact that in 1085 28 December fell on a Sunday.

Oswald Balzer refuted Bielowski's theory and pointed that Judith's death was on the night between 24–25 December 1086, and the birth of Bolesław was four months before, on 20 August. According to him, if Judith died on the night between 24–24 December, are possible discrepancies in determining the exact date of the event. All known sources who placed the death of Judith, would then right. Gallus wrote that Judith died shortly after giving birth to a son. Later sources interpret this as a death in childbirth and Cosmas of Prague followed this fact, despite he didn't received the information at first hand. Hence, his mistake would result in this point. In contrast, the right -indicated by Gallus- date of birth of Bolesław would be 20 August. In the medieval tradition the year began on 25 December. In that case, the reports of Cosmas must be concluded that Bolesław was born yet in 1085. This information, however, was in contradiction with the reports of the Kalendarz krakowski, who gave the year 1086. Judith was styled by the authors of the Kalendarz as "regina Polonia" (Queen of Poland in Latin), and this title could be associated with her father's coronation as King of Bohemia and Poland on 15 June 1086 (according to Cosmas). Karol Maleczyński refuted the arguments of Balzer, who accepted the date of the coronation of Vratislav II given by Cosmas. However, most researchers indicates that the coronation took place on 15 June 1085, so Judith could be called Queen a year earlier.

Karol Maleczyński determined that the death of Judith took place on the night between 24–25 December 1085, and Bolesław was born four months before, on 20 August. Researchers found that the date given by the Rocznik kapituły krakowskiej (24 December 1086) was the same established by Cosmas (25 December 1085). The difference in the year could be explained in the different of style dating followed by Cosmas, who began the year according to the Julian calendar on 1 January and Christmas (Nativitate in Latin) on 25 December. For Maleczyński, Kazimierz Jasiński not consider this calendar difference who occurs only during the period 25–31 December.

Archaeologist Wojciech Szafrański reasumed the theory of Bielowski: Judith of Bohemia died on 28 December 1085, and Bolesław was born two days before, on 26 December. According to Szafrański Cosmas used the term VIII Calends of January, with no specific date. However, in the Chronicle of Gallus should read that Judith died on Christmas Day, but on Sunday in the Octave of Christmas. Using such a broadened range of days, the investigator determined the birth of Boleslaw in the feast of Saint Stephen (26 December 26). For this reasons, the date of 1085 given by Bielowski is correct according to him. However, Jasiński pointed the weaknesses of the argument of Szafrański because Gallus has written about the Octave, but specifically about Christmas night, but the investigator didn't consider all other sources, as well as the achievements of research in genealogy.

Marian Plezia argued that Bolesław was born on 2 September 1085 or 1086. According to Gallus, the day of King Stephen of Hungary was also celebrated on 2 September. Jasiński considered this theory unfounded. In Poland the feast of King Stephen of Hungary is pointed by the Kalendarz krakowski and the kalendarz Kodeksu Gertrudy on 20 August. Besides, if Bolesław was born on 2 September, Gallus probably would be noted that this was the day after the celebration of Saint Giles (1 September), which was attributed to be the intercessor of his birth.

Kazimierz Jasiński placed the death of Judith in the night between 24–25 December 1086 and the birth of Bolesław on four months before, on 20 August. In this point he agrees with the findings of Balzer. He supported his views with additional arguments: All sources are based in the missing Rocznika kapituły krakowskiej, and the next known text of this source refers to events in the year 1086. Cosmas, writing his chronicle a few decades later, probably benefited from oral tradition and could make a mistake when he placed the year. His reports who placed the birth of Bolesław three days before the death of his mother denoted a quite short time.

Today is widely recognized the view of both Jasiński and Balzer, that Boleslaw most likely was born in the day of King Stephen of Hungary, 20 August 1086.

Early Years

Following Bolesław’s birth the political climate in the country changed. The position of Bolesław as an heir to the throne was threatened by the presence of Mieszko Bolesławowic, who was already seventeen at the time and was furthermore, by agreement with Władysław I Herman himself, the first in line to succeed. In all likelihood it was this situation that precipitated the young prince Mieszko’s demise in 1089. In that same year Wladyslaw I Herman’s first-born son Zbigniew was sent to a monastery in Quedlinburg, Saxony. This suggests that Wladyslaw I Herman intended to be rid of Zbigniew by making him a monk, and therefore depriving him of any chance of succession. This eliminated two pretenders to the Polish throne, secured young Bolesław’s inheritance as well as diminished the growing opposition to Wladyslaw I Herman among the nobility. Shortly after his ascension, however, Władysław I Herman was forced by the barons to give up the de facto reins of government to Count Palatine Sieciech. This turn of events was likely due to the fact that Herman owed the throne to the barons, the most powerful of whom was Sieciech.

Around this time Władysław I Herman married again. The chosen bride was Judith-Maria, daughter of Emperor Henry III and widow of King Solomon of Hungary, who after her wedding took the name Sophia in order to distinguish herself from Władysław I Herman's first wife. Through this marriage Bolesław gained three or four half-sisters, and as a consequence he remained the only legitimate son and heir. It's believed that the new Duchess was actively aiding Sieciech in his schemes to take over the country and that she became her mistress.

Position of Sieciech in Poland

In 1090 Polish forces under Sieciech's command, managed to gain control of Gdańsk Pomerania, albeit for a short time. Major towns were garrisoned by Polish troops, and the rest were burned in order to thwart future resistance. Several months later, however, a rebellion of native elites led to the restoration of the region’s independence from Poland. The following year a punitive expedition was organized, in order to recover Gdańsk Pomerania. The campaign was decided at the battle of the Wda River, where the Polish knights suffered a defeat despite the assistance of Bohemian troops.

Prince Bolesław’s childhood happened at a time when a massive political migration out of Poland was taking place, due to Sieciech’s political repressions. Most of the elites who became political refugees found safe haven in Bohemia. Another consequence of Sieciech’s political persecution was the kidnapping of Zbigniew by Sieciech’s enemies and his return from abroad in 1093. Zbigniew took refuge in Silesia, a stronghold of negative sentiment for both Sieciech as well as his nominal patron Władysław I Herman. In the absence of Sieciech and Bolesław, who were captured by Hungarians and kept captive, Prince Władysław I then undertook a penal expedition to Silesia, which was unsuccessful and subsequently obliged him to recognize Zbigniew as a legitimate heir. In 1093 Władysław I signed an Act of Legitimization which granted Zbigniew the rights of descent from his line. Zbigniew was also granted the right to succeed to the throne. Following Sieciech and Bolesław’s escape from Hungary, an expedition against Zbigniew was mounted by the Count Palatine. Its aim was to nullify the Act of Legitimization. The contestants met at the battle of Goplo in 1096, where Sieciech’s forces annihilated the supporters of Zbigniew. Zbigniew himself was taken prisoner, but regained his freedom a year later, in May 1097, due to the intervention of the bishops. At the same time his rights, guaranteed by the Act of Legitimization, were reinstated.

Simultaneously a great migration of Jews from Western Europe to Poland began circa 1096, around the time of the First Crusade. The tolerant rule of Władysław I Herman attracted the Jews who were permitted to settle throughout the entire kingdom without restrictions. The Polish prince, took great care of the Hebrew Diaspora, as he understood its positive influence on the growth of the country’s economy. The new Jewish citizens soon gained trust of the gentiles during the rule of Bolesław III.

Youth

Division of the country

Prince Zbigniew

In view of his father’s disapproval, and after discovering the plans of Sieciech and Duchess Judith-Sophia to take over the country Zbigniew gained an ally in the young prince Bolesław. Both brothers demanded that the reins of government should be handed over to them. It is difficult to believe, however, that Bolesław was making independent decisions at this point as he was only 12 years of age. It is postulated that at this stage he was merely a pawn of the Baron’s power struggle. Władysław I Herman, however, agreed to divide the realm between the brothers, each to be granted his own province while the Prince – Władysław I himself – kept control of Mazovia and its capital at Plock. Władysław also retained control of the most important cities i.e. Wroclaw, Krakow and Sandomierz. Zbigniew’s province encompassed Greater Poland including Gniezno, Kuyavia, Leczyca Land and Sieradz Land. Bolesław’s territory included Lesser Poland, Silesia and Lubusz Land.

The division of the country and the allowance of Bolesław and Zbigniew to co-rule greatly alarmed Sieciech, who then began preparing to dispose of the brothers altogether. Sieciech understood that the division of the country would undermine his position. He initiated a military settlement of the issue and he gained the Prince’s support for it. The position of Władysław I is seen as ambiguous as he chose to support Sieciech’s cause instead of his sons'.

Fight against Sieciech

In response to Sieciech’s preparations Bolesław and Zbigniew entered into an alliance. This took place at a popular assembly or Wiec organized in Wroclaw by a magnate named Skarbimir of the Awdaniec family. There it was decided to remove the current guardian of Bolesław, a noble named Wojslaw who was a relative of Sieciech, and arrange for an expedition against the Palatine. Subsequently, in 1099, the armies of Count Palatine and Prince Herman encountered the forces of Zbigniew and Bolesław near Zarnowiec by the river Pilica. There the forces of Bolesław and Zbigniew defeated Sieciech's army, and Władysław I Herman was obliged to permanently remove Sieciech from the position of Count Palatine. In the same year, at Christmas, Bolesław concluded to short-lived peace with Bohemia. The agreement was concluded in Žatec. According to Cosmas, Bolesław was appointed Miecznik (en: Sword-bearer) of his uncle Bretislaus II, Duke of Bohemia. In addition, the young prince would be paid the amount of 100 pieces of fine silver and 10 talents of gold annually as a tribute to Bohemia (it was about the land of Silesia, for which he paid tribute to Władysław I).

The rebel forces were then further directed towards Sieciechów, where the Palatine took refuge. Unexpectedly, Prince Władysław came to the aid of his besieged favorite with a small force. At this point, the Princes decided to depose their father. The opposition sent Zbigniew with an armed contingent to Masovia, where he was to take control of Płock, while Bolesław was directed to the South. The intention was the encirclement of their father, Prince Władysław I. The Prince predicted this maneuver and sent his forces back to Masovia. In the environs of Płock the battle was finally joined and the forces of Władysław I were defeated. The Prince was thereafter forced to exile Sieciech from the country. The Palatine left Poland around 1100/1101. He was known to sojourn in the German lands. However, he eventually returned to Poland but did not play any political role again. He may have been blinded.

First Years of Government

Struggle for the supremacy (1102–1106)

Division of Poland between Bolesław (red) and Zbigniew (green)

Władysław I Herman died on 4 June 1102. The country was divided into two provinces, each administered by one of the late prince’s sons. The extent of each province closely resembled the provinces that the princes were granted by their father three years earlier, the only difference being that Zbigniew also controlled Mazovia with its capital at Płock, effectively ruling the northern part of the kingdom, while his younger half-brother Bolesław ruled its southern portion. In this way two virtually separate states were created. According to some historians, Zbigniew tried to play the role of princeps or overlord, because at that time Bolesław was only 16 years-old. Because he was still too inexperienced to independently direct his domains, the local nobility gathered around him took great influence in the political affairs, included his teacher, Skarbimir from the Awdaniec family.

They conducted separate policies internally as well as externally. They each sought alliances, and sometimes they were enemies of one another. Such was the case with Pomerania, towards which Bolesław aimed his ambitions. Zbigniew, whose country bordered Pomerania, wished to maintain good relations with his northern neighbor. Bolesław, eager to expand his dominion, organized several raids into Pomerania and Prussia. In Autumn of 1102 Bolesław organized a war party into Pomerania during which his forces sacked Białogard.

As reprisal the Pomeranians sent retaliatory war parties into Polish territory, but as Pomerania bordered Zbigniew’s territory these raids ravaged the lands of the prince who was not at fault. Therefore in order to put pressure on Bolesław, Zbigniew allied himself with Bořivoj II of Bohemia, to whom he promised to pay tribute in return for his help. By aligning himself with Bolesław’s southern neighbor Zbigniew wished to compel Bolesław to cease his raids into Pomerania. Bolesław, on the other hand, allied himself with Kievan Rus and Hungary. His marriage to Zbyslava, the daughter of Sviatopolk II Iziaslavich in 1103, was to seal the alliance between himself and the prince of Kiev. However, Bolesław's first diplomatic move was to recognize Pope Paschal II, which put him in strong opposition to the Holy Roman Empire. A later visit of papal legate Gwalo, Bishop of Beauvais brought the church matters into order, it also increased Bolesław's influence.

Zbigniew declined to attend the marriage of Bolesław and Zbyslava. He saw this union and the alliance with Kiev as a serious threat. Thanks to bribery, he therefore prevailed upon his ally, Bořivoj II of Bohemia to invade Bolesław’s province, ostensibly to claim the Polish crown. Bolesław retaliated with expeditions into Moravia in 1104–1105, which brought the young prince not only loot, but also effectively disintegrated the alliance of Pomeranians and Zbigniew. During the return of the army, one part commanded by Żelisław were defeated by the Bohemians. Bolesław, who commanded the other part of the army, couldn't defeated them. Skarbimir, thanks to bribery, could stopped Bořivoj II. With a vast amount of money, the Bohemian ruler returned to his homeland and was concluded a short-lived peace with Bohemia. Then Bořivoj II ended his alliance with Zbigniew. In order to paralyze the alliance of Pomerania and his older brother, Bolesław carried out multiple attacks on northern land in the year 1103 (the battle of Kołobrzeg, where was defeated), and in the years 1104-1105, ended with success.

The intervention of Bolesław in the dynastic dispute in Hungary led him in a difficul political situation. At first, he supported the pretender Álmos,and marched to Hungary to help him. However, during the siege of Abaújvár in 1104, Álmos changed his mind and made peace conversations with his brother and rival King Coloman, at that point Zbigniew's ally. Bolesław then retired his troops from Hungary and in 1105 made a treaty with Coloman. It was decided then that Bolesław didn't support Álmos against the alliance Coloman-Zbigniew. In addition, the Hungarian King broke his agreements with the Bohemian Kingdom. The dynastic dispute in Prague between Bořivoj II and his cousin Svatopluk caused the intervention of Bolesław and his ally King Coloman in support of Svatopluk, with the main objective to placed him in the Bohemian throne. However, a new rebellion of Álmos forced Coloman and his army to return Hungary. Bolesław also decided to retreat. Svatopluk tried to master the city alone, but suffered a complete defeat; his attempt to seize power in Bohemia was unsuccessful.

Also in 1105, Bolesław entered into an agreement with his half-brother, in the same way like just a few years before entered with their stepmother Judith-Sophia (who in exchange of an abundant Oprawa wdowia (dower lands), secured her neutrality in Bolesław's political contest with Zbigniew). The treaty, signed in Tyniec, was a compromise of both brothers in foreign policy; however, no agreement about Pomerania was settled there. One year later, the treaty ended when Zbigniew refused to help his half-brother in his fight against Pomerania. While hunting, Bolesław was unexpectedly attacked by them. In the battle, the young prince almost lost his life. Bohemia, using the involvement of Bolesław in the Pomeranian affairs as an excuse, attacked Silesia. The prince tried to re-established the alliance with his half-brother, without success. The effect of this refusal was the rapprochement to the Bohemian Kingdom in 1106. Bolesław managed to bribe Bořivoj II and have him join his side in the contest against Zbigniew and shortly after formally allied himself with Coloman of Hungary. With the help of his Kievan and Hungarian allies Bolesław attacked Zbigniew’s territory, and began a civil war for the supreme power in Poland. The allied forces of Bolesław easily took control of most important cities including Kalisz, Gniezno, Spycimierz and Łęczyca, in effect taking half of Zbigniew’s lands. Through a mediation of Baldwin, Bishop of Kraków, a peace treaty was signed at Łęczyca, in which Zbigniew officially recognized Bolesław as the Supreme Prince of all Poland. However, he was allowed to retain Masovia as a fief.

Sole Ruler of Poland

First Expedition to Bohemia and exile of Zbigniew

In 1107 Bolesław III along with his ally King Coloman of Hungary, invaded Bohemia in order to aid Svatopluk in gaining the Czech throne. The intervention in the Czech succession was meant to secure Polish interests to the south. The expedition was a full success: on 14 May 1107 Svatopluk was made Duke of Bohemia in Prague.

Later that year Bolesław undertook a punitive expedition against his brother Zbigniew. The reason for this was that Zbigniew didn't follow his orders and refused to burn down one of the fortresses of Kurów near Puławy. Another reason was that Zbigniew not followed his duties as a vassal and didn't provide military aid to Bolesław for a campaign against the Pomeranians. In the winter of 1107–1108 with the help of Kievan and Hungarian allies, Bolesław began a final campaign to rid himself of Zbigniew. His forces attacked Mazovia, and quickly forced Zbigniew to surrender. Following this Zbigniew was banished from the country and with his followers, took refuge in Prague, where he found support in Svatopluk. From then Bolesław was the sole lord of the Polish lands, though in fact his over-lordship began in 1107 when Zbigniew paid him homage as his feudal lord.

In 1108 the balance of power in Europe changed. Svatopluk decided to paid homage to Emperor Henry V and in exchange, received from him the formal investidure of Bohemia. At the same time, King Coloman of Hungary was under attack by the combined forces of the Holy Roman Empire and Bohemia. Svatopluk also directed an attack to Poland; in this expedition took part Zbigniew and his followers. Bolesław avoided a direct confrontation because was busy again in his fight against Pomerania. Now, the Polish-Hungarian coalition decided to give help and shelter to Bořivoj II. Later that year, Bolesław and Coloman made an new expedition against Bohemia. This expedition was prompted by the invasion of the German-Bohemian coalition to Hungary (siege to Pozsony Castle) and the fact that Svatopluk, who owed Bolesław his throne, didn't honor his promise in which he returned Silesian cities seized from Poland (Racibórz, Kamieniec, Koźle among others) by his predecessors. Bolesław then decided to restore Bořivoj II in the Bohemian throne. This attempt was unsuccessful as a result of the attack of the Pomeranians. Bolesław was forced to bring his army to the north, where could repelled the invasion. Thanks to this situation, Bořivoj II failed to regain the throne.

Polish-German War of 1109

In response to Bolesław’s aggressive foreign policy, German king and Holy Roman Emperor Henry V undertook a punitive expedition against Poland in 1109 (the later called Polish-German War. In this fight, Henry V was assisted by Czech warriors provided by Svatopluk of Bohemia. The alleged reason for the war was the exile of Zbigniew and his restoration. Bolesław received an ultimatum from the German King: he abandoned the expedition against him only if Zbigniew was restored with half of Poland as a rule, the formal recognition of the Holy Roman Empire as overlord and the payment of 300 pieces of fine silver as a regular tribute. Bolesław rejected. During the negociations between Germany and Poland, the Polish ruler was in the middle of a war against Pomerania. On the west side of the Oder river, Henry V hurriedly gathered knights for his expedition against Poland. Before the fight ended in Pomerania, the German troops have been able to approach Głogów.

Battle of Hundsfeld, from The Polish Chronicle of Marcin Bielski (1597)

The military operations mainly taken place in southwestern Poland, in Silesia, where Henry V’s army laid siege to major strongholds of Głogów, Wrocław and Bytom Odrzański. At this time along with the defense of towns, Bolesław was conducting a highly effective guerrilla war against the Holy Roman Emperor and his allies, and eventually he defeated the German Imperial forces at the legendary Battle of Hundsfeld on 24 August 1109, who received that name because the dogs devoured the many corpses left in the battlefield. In the end Henry V was forced to withdraw from Silesia and Poland altogether. The heroic defense of towns by villagers, where Polish children were used as human shields by the Germans, in large measure contributed to the German inability to succeed and gave the battle a national character.

Second Expedition to Bohemia

In 1110 Bolesław undertook an unsuccessful military expedition against Bohemia. His intention was to install yet another pretender on the Czech throne, Soběslav I, who sought refuge in Poland. During the campaign won a decisive victory against the Czechs at the Battle of Trutina on 8 October 1110; however, following this battle he ordered his forces to withdraw further attack against Bohemia. The reason for this is speculated to be the unpopularity of Soběslav I among Czechs as well as Bolesław’s unwillingness to further deteriorate his relations with the Holy Roman Empire. In 1111 a truce between Poland and the Holy Roman Empire was signed which stipulated that Soběslav I would be able to return to Bohemia while Zbigniew would be able to return Poland. Bolesław probably also agreed with the return of his half-brother as a result of pressure from the many supporters of the exiled prince in 1108, who according to the reports of Gallus Anonymus was surrounded to bad advisers (in this group unfavorable to Bolesław was probably Martin I, Archbishop of Gniezno). Once in Poland, Zbigniew could claim the sovereignty over his previous domains at the instigation of this group. The first step towards this was his presence in the Advent ceremonial (which was forbidden to him by Bolesław after recognizing him as his overlord in Łęczyca in 1107), which is reserved only for rulers. Zbigniew arrived surrounded by attendants, being carried before him a sword. This could be perceived by Boleslaw as an act of treason and caused a definitive breach in their relationship, under which Zbigniew was the vassal and Boleslaw the ruler. Probably these factors influenced Bolesław's decision of a terrible punishment to Zbigniew: a year later, in 1112, he was blinded on Bolesław’s orders.

Excommunication

Martin I, Archbishop of Gniezno.

The blinding of Zbigniew caused a strong negative reaction among Bolesław's subjects. It should be noted that unlike for instance in the east, blinding in medieval Poland was not accomplished by burning the eyes out with a red hot iron rod or knife, but a much more brutal technique was employed. The condemned man's eyes were pried out using special pliers. The convict was made to open his eyes and if he did not do so, his eyelids were torn out along with his eyeballs.

Contemporary sources don't provide clear information if Bolesław was indeed excluded from the community of the Church. Is generally believed that Archbishop Martin I of Gniezno (who was a strong supporter of Zbigniew) excommunicated Bolesław for committing this crime against his half-brother. The excommunication exempted all Bolesław's subjects from his oath to obedience. The prince was faced with a real possibility of uprising, of the sort that deposed Bolesław the Bold. Seeing his precarious situation Bolesław sought the customary penance that would reconcile the high priesthood. According to Gallus Anonymus, Bolesław first fasted for forty days and made gifts to the poors:

(...)He slept in ashes and sackcloth, among the streams of tears and sobs, as he renounced communion and conversation with people.

It's possible that Bolesław decided to celebrated a public penance as a result of the negative public response to the blinding of Zbigniew. His intention with this was to rebuild his weakened authority and gain the favor of Zbigniew's supportets. Punishment of blinding was used in medieval Europe to the rebellious nobles. This act of Bolesław against his half-brother could be received by the Polish society as a breach of the principle of solidarity among the members of the ruling dynasty, accepting the foundation of public order.

According to Gallus, Bolesław also sought and received forgiveness from his half-brother. In the next part of his penance, the prince made a pilgrimage to Hungary to the Abbeys of Saint Giles in Somogyvár and King Saint Stephen I in Székesfehérvár. The pilgrimage to the Abbey of Saint Giles also had a political goal; Bolesław strengthened his ties of friendship and alliance with the Arpad dynasty. Following his return to Poland, Bolesław even traveled to Gniezno to pay further penance at the tomb of Saint Adalbert of Prague, were poor people and clergy received numerous costly gifts from the prince. Only after this the excommunication was finally lifted. Following his repentance the Polish prince made a vague commitment to the Church.

About Zbigniew's death there are not preserved information. In the obituary of the Benedictine monastery in Lubiń dated 8 July 1113 was reported the death of a monk in Tyniec called brother Zbigniew. Historians believed that he could be Bolesław's half-brother. The information marked that his burial place was in the Benedictine monastery of Tyniec.

Conquest and conversion of Pomerania

Map of Pomerania including the island of Rugia (17th century).

The separation of Pomerania during the reign of Casimir I the Restorer contributed to the weakening of the Polish state, and subsequent rulers during the second half of the 11th century weren't able to unite all the lands that once belonged to Mieszko I and Bolesław I the Brave. All attempts made to reconquer this area failed. Only after defeating Zbigniew and repelling the claims of Bohemia against Silesia during the Polis-German War of 1109, Bolesław III Wrymouth was able to directed the expansion to the West, which he intended to return to Poland.

Strengthening the Polish-Pomeranian borders

The issue of conquest of Pomerania had been a lifelong pursuit for Bolesław III Wrymouth. His political goals were twofold; first – to strengthen the Polish border on the Noteć river line, second – to subjugate Pomerania with Polish political overlordship but without actually incorporating it into the country with the exception of Gdansk Pomerania and a southern belt north of river Noteć which were to be absorbed by Poland. By 1113 the northern border has been strengthened. The fortified border cities included: Santok, Wieleń, Nakło, Czarnków, Ujście and Wyszogród. Some sources report that the border began at the mouth of river Warta and Oder in the west, ran along the river Noteć all the way to the Vistula river.

Before Bolesław III began to expand in Gdańsk Pomerania (Pomerelia), he normalized his political relations with Bohemia. This took place in 1114 at a great convention on the border of the Nysa Kłodzka river. In addition to Bolesław also assisted Bohemian princes of the Premyslid line: Vladislaus I, Otto II the Black and Soběslav I. The pact was sealed by the marriage of Bolesław (a widower since his wife Zbyslava's death) with Vladislaus I and Otto II's sister-in-law, the German noblewoman Salomea of Berg.

The conquest of Gdańsk Pomerania

After being normalized his relations with Bohemia, Bolesław directed his efforts against Prussia, and in 1115 he made a victorious expedition, ravaging their tribal lands. As a result, the north-east border was at peace, which allowed to freely prepare the invasion to Gdańsk Pomerania. The conquest of this part of the Pomeranian lands (made during the years 1115-1119), crowned a long-time struggle of previous Polish rulers. The result was the complete incorporation of the territories on the Vistula River, including the castellany of Nakło, to Poland. Northern borders were established Polish Duchy probably on the line along the rivers Gwda and Uniesta (in later times currents of these rivers were the boundary between Pomerania and the Oder Slavic). It's also possible that the border ran along the Łeba.

The local rulers of the conquered Gdańsk and Słupsk were removed from power and replaced by Polish nobles. Bolesław also introduced Polish clerical organization, which was made in order to protect his interests in that territory. However, these areas refused to follow the church organization. The incorporation to the Polish Church occurred only during 1125-1126 at the time of the visit of Papal Legate Gilles, Cardinal-Bishop of Tusculum.

Rebellion of Skarbimir

During Bolesław's Pomeranian campaign a formidable rebellion by leaded by Count Palatine Skarbimir from the Awdaniec family began. The rebellion was quelled by the prince in 1117 and the mutinous nobleman were blinded as punishment. The conflict between Bolesław and the Awdaniec family is difficult to explained due to the lack of sources. The cause was probably the growing influence of the family, the ambition and jealousy of Skarbimir against Bolesław and his increased popularity. Another probable factor was the desire to put Władysław II, Bolesław's first-born son, as the sole ruler after his death or also Boleslaw's fears to lose his position, as it was in the conflict with Sieciech. It was also suggested that Skarbimir entered in contacts with Pomeranians and Vladimir II Monomakh, Grand Prince of Kievan Rus'. Medieval historiography also associated the rebellion with the Law of Succession issued by Boleslaw. The problem with the principle of inheritance appeared between 1115-1116 (after the birth of his second son Leszek, first-born from his second marriage). According to one hypothesis Skarbimir objected the adoption of the statute who changed the traditional Polish succession customs. In the suppression of the rebellion played a major role Piotr Włostowic of the Labedz family, who replaced Skarbimir as Count Palatine. Defeated, Skarbimir received a minor punishment from Bolesław. The rebellion of Skarbimir also rested importance to the conquest of Gdańsk Pomerania.

Intervention of Kievan Rus'

Probably in the rebellion of Skarbimir intervened the Rurikid ruler Vladimir II Monomakh and his sons. In 1118 Monomakh incorporated Volhynia to his domains and expelled his ruler, Yaroslav Sviatopolkovich, who sought refuge firstly in Hungary, then in Poland. In Yaroslav's place, Monomakh put his son Roman as a ruler of Volhynia, and after his early death in 1119, replaced him with another son, Andrew, who in 1120 invaded Polish territory with the support of the Kipchaks tribe. A year later, Bolesław with the exiled Yaroslav (who was his brother-in-law), organized a retaliatory expedition to Czermno. After this, for several years Bolesław intervened in the dynastic disputes of the House of Rurik.

During the 1120s the Kievan princes continue their expeditions against Poland. The neutrality of the neighboring Principality of Peremyshl was attributed to Count Palatine Piotr Włostowic, who in 1122 captured Prince Volodar. A year later Bolesław intervened again in Volhynia, where he wanted to restore Yaroslav. The expedition (aided by the Bohemian, Hungarian, Peremyshl and Terebovl forces) failed due to the death of Yaroslav and the stubborn resistance of the besieged Volodymyr-Volynskyi, aided by Skarbimir's supporters. This failed military expedition led to disturbances in the Polish-Hungarian-Halych alliance.

Conquest of Western Pomerania

In 1121 (or 1119) Pomeranian Dukes Wartislaw I and Swietopelk I were defeated by Bolesław's army at the battle of Niekładź near Gryfice. Polish troops ravaged Pomerania, destroyed native strongholds, and forced thousands of Pomeranians to resettle deep into Polish territory. Bolesław's further expansion was directed to Szczecin (1121-1122). He knew that this city was well defended by both the natural barrier of the Oder river and his well-built fortifications, like Kołobrzeg. The only way to approach the walls was through the frozen waters of a nearby swamp. Taking advantage of this element of surprise, Bolesław launched his assault from precisely that direction, and took control of the city. Much of the population was slaughtered and the survivors were forced to paid homage to the Polish ruler.

A further step is probably fought battles on the western side of the Oder River, where Boleslaw had addressed areas to the Lake Morzyce (now the German Müritz). These areas were outside the territorial scope of Pomeranians. In parallel with the expansion of the Polish ruler to the west continued the conquest of these lands by Lothair, Duke of Saxony (and future Holy Roman Emperor). According to contemporary sources, a Saxon army approaching from above the Elbe River in the direction of today's Rostock. They conquered the Warinis, Circipanes, Kessinians and part of the Tollensers tribes. The expansion led by the two rulers was probably the result of earlier unknown agreements. This was the first step for the later christianization of Pomeranian lands.

In 1122 Bolesław finally conquered Western Pomerania, who became a Polish fief. Duke Wartislaw I was forced to paid homage to the Polish ruler, paying an annual tribute of 500 marks of fine silver and the obligation to give military aid to Poland at Bolesław’s request. In subsequent years the tribute was reduced to 300 marks. This success enabled Bolesław to made further conquests. In 1123 his troops even reached to Rügen, but didn't mastered these areas.

According to modern historiography, Bolesław began to pay tribute to Emperor Henry V, at least from 1135. Is believed that the amount was 500 marks of fine silver annually. It's unknown why Bolesław began to paid homage to Henry V, as sources doesn't transmited any reference about the Polish ruler being tributary of the Holy Roman Empire in the period 1121-1135.

Christianization of Western Pomerania

Saint Otto of Bamberg.

In order to make Polish and Pomeranian ties stronger, Bolesław organized a mission to Christianize the newly acquired territory. The Polish monarch understood that the Christianization of the conquered territory would be an effective means of strengthening his authority there. At the same time he wished to subordinate Pomerania to the Gniezno Archbishopric. Unfortunately first attempts made by unknown missionaries did not make the desired progress. Another attempt, officially sponsored by Bolesław and led by Bernard the Spaniard, who traveled to Wolin during 1122-1123, has ended in another failure. The next two missions were carried out in 1124–1125 and 1128 by Bishop Otto of Bamberg (called the Apostle of Pomerania). After appropriate consultation with Bolesław, Bishop Otto set out on a first stage of Christianization of the region in 1124. In his mission Otto stayed firstly at Bolesław's court, where he was provided with appropriate equipment, fire and several clergymen for his trip to Pomerania.

The Bishop was accompanied throughout his mission by the Pomeranian ruler Wartislaw I, who greeted him on the border of his domains, in the environs of the city of Sanok. In Stargard the pagan prince promised Otto his assistance in the Pomeranian cities as well as help during the journey. He also assigned 500 armored knights to act as guards for the bishop’s protection, and obtain the baptism of the elders tribal leaders. Primary missionary activities were directed to Pyrzyce, then the towns of Kamień, Wolin, Szczecin and once again Wolin. In the first two towns the christianization went without resistance. In Kamień the task was facilitated by the intercession of Wartislaw I's own wife and dignataries. At Szczecin and Wolin, which were important centers of Slavic paganism, opposition to conversion was particularly strong among the pagan priests and local population. The conversion was finally accepted only after Bolesław lowered the annual tribute imposed on the Pomeranians. Four great pagan temples were torn down and churches were built in their places. Otto's mission of 1124 ended with the erection of bishoprics in Lubusz for Western Pomerania and in Kruszwica for Eastern Pomerania (Gdańsk), which was subordinated to the Archbishopric of Gniezno.

In 1127 the first pagan rebellions began to take place. These were due to both the large tribute imposed by Poland as well as a plague that descended on Pomerania and which was blamed on Christianity. The rebellions were largely instigated by the old pagan priests, who had not come to terms with their new circumstances. Wartislaw I confronted these uprisings with some success, but was unable to prevent several insurgent raids into Polish territory. Because of this Bolesław was preparing a massive punitive expedition that may have spoiled all the earlier accomplishments of missionary work by Bishop Otto. Thanks to Otto’s diplomacy direct confrontation was avoided and in 1128 he embarked on another mission to Pomerania. Wartislaw I greeted Otto at Demmin with some Polish knights. This time more stress was applied to the territories west of the Oder River, i.e. Usedom, Wolgast and Gützkow, which weren't under Polish suzerainty. The final stage of the mission returned to Szczecin, Wolin and Kamień. The Christianization of Pomerania is considered one of the greatest accomplishments of Bolesław’s Pomeranian policy.

In 1129 Bolesław concluded with Niels, King of Denmark an alliance directed against Wartislaw I and the attempts of Lothair III, King of Germany to subordinate Western Pomerania. In retaliation for the sack of Płock by Wartislaw I in 1128, Polish-Danish troops taken the Western Pomeranian islands of Wolin and Usedom.

At end of the 1120s Bolesław began to implement an ecclesiastical organization of Pomerania. Gdańsk Pomerania was added to the Diocese of Włocławek, known at the time as the Kujavian Diocese. A strip of borderland north of Noteć was split between the Diocese of Gniezno and Diocese of Poznan. The bulk of Pomerania was however made an independent Pomeranian bishopric (whose first Bishop was one of the participants in the missionary expedition and former Polish royal chaplain, Adalbert), set up in the territory of the Duchy of Pomerania in 1140, and after Bolesław had died in 1138 the duchy became independent from Poland.

The project of Archbishop Norbert of Magdeburg

During the 1130s a project was designed by Norbert, Archbishop of Magdeburg, under which Pomerania would be divided between two dioceses subordinated to the Archbishopric of Magdeburg. At the same, he revivied the old claims about Magdeburg's ecclesiastical sovereignty over all Poland. A first Bull was prepared already in 1131, but never entered into force. Despite adversity, Norbert continued his actions to subdue the Polish Church during 1132-1133. For the Polish bishops, a call was made in the Curia.

The Polish bishops didn't appear before Pope Innocent II, which resulted in the issuing of the Bull Sacrosancta Romana in 1133, which confirmed the sovereignty of the Archbishopric of Magdeburg over the Polish Church and the projected Pomeranian dioceses. The formal privilegium maius was the culmination of Norbert's efforts. Bolesław, trying to save his past efforts in Pomeranian politics, opted for his submission at Merseburg in 1135.

Conquest of Rügen and alliance with Wartislaw I

To consolidate his power over Pomerania Bolesław conducted in 1130 an expedition to the island of Rügen. For this purpose, he concluded an alliance with the Danish duke Magnus Nilsson (his son-in-law) who provided him with a fleet in exchange for support in his efforts to obtain the Swedish throne. The fleet of Magnus transported Polish troops to the shores of the island of Rügen. However, the intended battle on the island doesn't happen, because the Rani at the sight of the Polish-Danish combined forces recognize Bolesław 's overlordship.

After the successful invasion to the Danish capital, Roskilde in 1134 Bolesław formed an alliance with Wartislaw I of Pomerania against King Eric II of Denmark (an ally of Emperor Lothair III). The role of the Polish prince was limited only to aid the House of Griffins, not due while the real interest in Danish affairs. The Danish, after repelling the first attack, in retaliation led an expedition who led to their expansion into the lands of Pomerania.

Congress of Merseburg

Political Background

In 1125 Henry V, Holy Roman Emperor and King of Germany, died. His successor, Lothair of Supplinburg, has been embroiled in disputes over his inheritance. For the Imperial crown, he became involved in the affairs of the Papacy. In 1130 there was a double election to the Apostolic See. Lothair supported Pope Innocent II, hoping in this way to secure his own coronation. Contrary to was expected, Lothair's Imperial coronation didn't end his disputes against the contenders for the German throne.

In 1130 Bolesław controlled the areas situated on the left bank of the Oder river on the island of Rügen. Germany also wanted to control these lands, but the internal political situation and the involvement in the civil war in Hungary, however, didn't allow an armed conflict. The Bull Sacrosancta Romana of 1133 give the Archbishopric of Magdeburg sovereign rights over the Pomeranian dioceses instituted by Bolesław.

The death of King Stephen II of Hungary in 1131 led the country into civil war between two claimaints to the throne: Béla the Blind (son of Álmos, Duke of Croatia) and Boris (the alleged son of King Coloman). Boris sought the help of the Polish ruler, who hoped for a closer alliance with Hungary and cooperation with the Kievan Rus' princes (Boris was a son of a daughter of Vladimir II Monomakh). However, Bolesław overestimated his strength against Béla, who counted with the support of almost all his country. The Polish army faced the combined forces of Hungary, Bohemia, Austria and Germany in the Battle of the Sajó river (22 July 1132), where the coalition had a complete victory over the Polish prince, who was forced to retreat.

The success in Hungary was by Bohemian ruler Soběslav I, an Imperial vassal, who during the years 1132-1134 repeatedly led invasions to Silesia. The issue over the property of Silesia was subjected to the decision of Lothair III.

Preparations for the Congress

In February 1134 Soběslav I of Bohemia and dignataries of King Béla II of Hungary, together with Bishop Peter of Székesfehérvár went to Altenburg, where they presented their allegations against the Polish ruler. They asked the intervention of the Holy Roman Empire (preliminary requests occurred two years earlier). Lothair III accepted the request, acting as an arbitrator in the dynastic disputes in Central Europe.

At the same time Béla II and Prince Volodymyrko of Peremyshl undertook a military expedition against Poland. The combined forces occupied Lesser Poland, reaching to Wiślica. Shortly after, Bolesław received a summons to the Imperial court at Magdeburg on 26 June 1135. Playing for time, however, he only send deputies. The emperor sent another delegation and requested a personal appearance of the Polish ruler, setting a new date on 15 August 1135, this time in Merseburg. Bolesław realized that without an agreement with Lothair III he couldn't maintain the control over the newly conquered lands on the west side of the Oder and the island of Rügen.

Even before the Congress of Merseburg Bolesław persuaded one of ruling princes of Western Pomerania, Ratibor I and to made an expedition against Denmark. It was a clear expression of ostentation to Emperor Lothair III because the King of Denmark was a German vassal. The fleet formed by 650 boats (with 44 knights and 2 horses) was sent to the rich Norwegian port city of Kungahälla (now Kungälv in Sweden).

Provisions of the Congress

Tge Congress took place on 15 August 1135. During the ceremony, Emperor Lothair III recognized the rights of the Polish ruler over Pomerania. In retribution, Bolesław agreed to paid homage for the Pomeranian lands and the Principality of Rügen, with the payment of 6000 pieces of fine silver from these lands to the Holy Roman Empire; however he remained fully independent ruler of his main realm, Poland. With Bolesław's death in 1138, Polish authority over Pomerania ended, triggering competition of the Holy Roman Empire and Denmark for the area. The conflict with Hungary also ended, with Bolesław recognizing Béla II's rule. The agreement was sealed with the betrothal of Bolesław's daughter Judith with Béla II's Géza (this marriage never took place). In case of the Bohemian-Polish dispute the Imperial mediation failed. Bolesław argued he must be treated as a sovereign ruler, who wasn't the case of Soběslav I, an imperial vassal. Lothair III, unable to come to an agreement with the Polish ruler, proposed to discuss the matter in subsequent negotiations.

The Congress ended with church ceremonies, during which Bolesław carried the imperial sword. This was an honor granted only to sovereign rulers. An indirect goal of Polish diplomacy was the successful invalidation of the Papal Bull of 1133 and the recognition of metropolitan rights of the Archbishopric of Gniezno at the Synod in Pisa in 1135. On 7 July 1136 was issued the protectionist Bull Ex commisso nobis a Deo under which Pope Innocent II confirmed the unquestioned sovereignty of the Archbishopric of Gniezno over the Polish dioceses.

Last years and death

Normalization of relations with his neighbors

After entering in the imperial sphere of influence, Poland normalized his relations with Bohemia at the Congress of Kłodzko on 30 May 1137 (the so-called Peace of Kłodzko), but the details of this agreement are unknown. This treaty was confirmed in the town of Niemcza, where Władysław, the eldest son of Bolesław, stood as godfather in the baptism of Vladislaus, Soběslav I's son.

In the last years of his life, Bolesław's main concern was to arranged political marriages for his children in order to strengthening his relations with neighboring countries. In 1137 Bolesław reforced his relations with Kievan Rus' with the marriage of his son Bolesław with Princess Viacheslava, daughter of Vsevolod, Prince of Pskov. In the year of his death, by contrast, finally normalized his relations with Hungary through the marriage of his son Mieszko with Princess Elizabeth, daugther of King Béla II.

Death

Bolesław III Wrymouth died on 28 October 1138, probably in the town of Sochaczew​​. There are no records about the circumstances of his death. 12th century sources didn't provide information about his place of burial. It was only in the 15th century, when Jan Długosz recorded that the Prince's tomb was in the Masovian Blessed Virgin Mary Cathedral in Płock. However, he didn't showed from where took this information. Presumably the chronicler took this report from the lost Rocznik mazowiecki. Wawrzyniec Wszerecz, Canon of Płock during the 16th-17th century, wrote that Bolesław was in a common coffin at the Cathedral, where the remains of his father Władysław I Herman and several other Piast Masovian rulers were also placed.

Marriages and Issue

By 16 November 1102 Bolesław married Zbyslava (b. ca. 1085/90 – d. ca. 1112), daughter of Grand Duke Sviatopolk II of Kiev. They had three children:

10. Henry (b. 1131 – d. 18 October 1166).
11. Agnes (b. 1137 – d. aft. 1182), married in 1151 to Mstislav II, Prince of Pereyaslavl and Grand Prince of Kiev since 1168.
12. Casimir II the Just (b. 1138 – d. 5 May 1194).

Statute of Succession

Before his death in 1138, Bolesław Wrymouth published his testament dividing his lands among four of his sons. The "Senioral Principle" established in the testament stated that at all times the eldest member of the dynasty was to have supreme power over the rest and was also to control an indivisible "senioral part": a vast strip of land running north-south down the middle of Poland, with Kraków its chief city. The Senior's prerogatives also included control over Pomerania, a fief of the Holy Roman Empire. The "senioral principle" was soon broken, leading to a period of nearly 200 years of Poland's feudal fragmentation.

Church foundations

Sarcophagus Bolesław III in Plock Cathedral

Prince Bolesław III was not only a predatory warrior but also a cunning politician and a diplomat. He was also a patron of cultural developments in his realm. Like most medieval monarchs, he founded several churches and monasteries most important of which are the monastery of Canons regular of St. Augustinein Trzemeszno, founded in the 12th century, and a Benedictine monastery of Holy Cross atop the Łysa Góra which was founded in place of an ancient pagan temple. Also the first major Polish chronicle written by one Gallus Anonymus dates back to the reign of Prince Bolesław III.
