John I Albert

John I Albert (Polish: Jan I Olbracht) (27 December 1459 – 17 June 1501) was King of Poland (1492–1501) and Duke of Głogów (1491–1498).

Early life and succession

John was the third son of Casimir IV Jagiellon, King of Poland, and Elisabeth Habsburg of Hungary, daughter of the King Albert of Hungary. As crown prince, he distinguished himself by his brilliant victory over the Tatars at Kopersztyn (1487). In 1490, the Hungarian nobility proclaimed John King of Hungary at the Rákos diet. He was, however, defeated by his brother, King Vladislaus II of Hungary. In 1492, John succeeded his father as King of Poland thanks to the key intervention of his brother Friedrich Jagiellon, archbishop of Kraków and archbishop of Gniezno. Friedrich achieved the coronation of John. However, losses of revenue due to the secession of Lithuania placed John at the mercy of the Polish sejmiks, or local diets, where the szlachta, or local nobles, made their subsidies dependent on the king's subservience.

John, King of Denmark

John (Danish and Norwegian: Hans; Swedish: Johan; né Johannes) (2 February 1455 – 20 February 1513) was a Scandinavian monarch under the Kalmar Union. He was King of Denmark (1481–1513), Norway (1483–1513) and as John II (Swedish: Johan II) Sweden (1497–1501). From 1482 to 1513, he was concurrently Duke of Schleswig and Holstein in joint rule with his brother Frederick.

The three most important political goals of King John were the restoration of the Kalmar Union, reduction of the dominance of the Hanseatic League, and the building of a strong Danish royal power.

John I (bishop of Wrocław)

John I, Bishop of Wrocław was an early Bishop of Wrocław. Very little is known of him except his office was from 1063 till his death in 1072. The historical records from his time in office are very sparse. Poland had been ravaged by a pagan uprising that left diocese of Wroclaw, founded a generation earlier, in a precarious condition. He spent most of his bishopric rebuilding the church. It is probable that he was the bishop who consecrated the cathedral built by Casimir the Restorer.
