The Kingdom of Dalmatia (Croatian: Kraljevina Dalmacija, German: Königreich Dalmatien; Italian: Regno di Dalmazia) was a crown land of the Austrian Empire (1815-1867) and the Cisleithanian half of Austria-Hungary (1867-1918). It encompassed the entirety of the region of Dalmatia with its capital at Zadar.
The Habsburg Monarchy had annexed the lands of Dalmatia after the Napoleonic War of the First Coalition: when Napoleon Bonaparte launched his Italian Campaign into the Habsburg duchies of Milan and Mantua in 1796, culminating in the Siege of Mantua, he compelled Emperor Francis II to make peace. In 1797 the Treaty of Campo Formio was signed, whereby the Habsburg emperor renounced the Austrian Netherlands and officially recognized the independence of the Italian Cisalpine Republic. In turn, Napoleon ceded to him the possessions of the Republic of Venice, including the Dalmatian coast (Venetian Dalmatia) and the Bay of Kotor (Venetian Albania). La Serenissima had sided with Austria in order to defend her Domini di Terraferma and was occupied by French troops on 14 May 1797. The treaty ended the centuries-long history of the Venetian Republic.
Dalmatia (Croatian: Dalmacija, [dǎlmaːt͡sija]; see names in other languages) is one of the four historical regions of Croatia, alongside Croatia proper, Slavonia, and Istria.
Dalmatia is a narrow coastal region, stretching from island of Rab in the north to the Bay of Kotor in the south. The hinterland (Dalmatian Zagora) ranges in width from fifty kilometres in the north, to just a few kilometres in the south; it is mostly covered by rugged Dinaric Mountains. 79 islands (and about 500 islets) run parallel to the coast, the largest (in Dalmatia) being Brač, Pag and Hvar. The largest city is Split, followed by Zadar, Dubrovnik, and Šibenik.
Name of the region stems from an Illyrian tribe called the Dalmatae, who lived in the area in classical antiquity. Later it became a Roman province, and as result a Romance culture emerged, along with the now-extinct Dalmatian language, later largely replaced with related Venetian. With the arrival of Croats to the area in the 8th century, who occupied most of the hinterland, Croatian and Romance elements began to intermix in language and the culture. During the Middle Ages, its cities were often conquered by, or switched allegiance to, the kingdoms of the region. The longest-lasting rule was the one of the Republic of Venice, which controlled most of Dalmatia between 1420 and 1797, with the exception of the small but stable Republic of Ragusa (1358–1808) in the south. Between 1815 and 1918, it was as a province of Austrian Empire known as the Kingdom of Dalmatia. After the Austro-Hungarian defeat in World War I, Dalmatia was split between the Kingdom of Serbs, Croats, and Slovenes which controlled most of it, and the Kingdom of Italy which held several smaller parts, and after World War II, SFR Yugoslavia took control over the complete area.
The Theme of Dalmatia (Greek: θέμα Δαλματίας/Δελματίας, thema Dalmatias/Delmatias) was a Byzantine theme (a military-civilian province) on the eastern coast of the Adriatic Sea in Southeastern Europe, headquartered at Jadera (later called Zara and now Zadar).
Dalmatia first came under Byzantine control in the 530s, when the generals of Emperor Justinian I (r. 527–565) seized it from the Ostrogoths in the Gothic War. The invasions of the Avars and Slavs in the 7th century destroyed the main cities and overran much of the hinterland, with Byzantine control limited to the islands and certain new coastal cities -with local autonomy and called Dalmatian City-States- such as Spalatum and Ragusium, while Jadera became the local episcopal and administrative center, under an archon. These coastal cities were the refuge of the autochthonous Dalmatian neolatins, who created the original eight Dalmatian city-states (Vecla, Crespa, Arba, Jadera, Tragurium, Spalatum, Ragusium and Cattaro).
Dalmatia was an ancient Roman province. Its name is probably derived from the name of an Illyrian tribe called the Dalmatae which lived in the area of the eastern Adriatic coast in Classical antiquity. It encompassed much of present-day Albania, Croatia, Bosnia and Herzegovina, Montenegro, Serbia, Kosovo etc, an area significantly larger than the current region of Dalmatia.
The region was the northern part of the Illyrian kingdom between the 4th century BC until the Illyrian Wars in the 220s BC and 168 BC when the Roman Republic established its protectorate south of the river Neretva. The area north of the Neretva was slowly incorporated into Roman possessions until the province of Illyricum was formally established c. 32-27 BC.
The Dalmatia region then became part of the Roman province of Illyricum. Between 6 and 9 AD the Dalmatians raised the last in a series of revolts together with the Pannonians, but the rebellion was finally crushed, and in 10 AD Illyricum was split into two provinces, Pannonia and Dalmatia. The province of Dalmatia spread inland to cover all of the Dinaric Alps and most of the eastern Adriatic coast. Dalmatia was the birthplace of the Roman Emperor Diocletian, who, upon retirement from Emperor, built Diocletian's Palace near Salona in today's Croatia.
