Syrmia County

Syrmia County (Srijemska županija, Сремска жупанија, Szerém vármegye, Komitat Syrmien) was a historic administrative subdivision (županija) of the Kingdom of Croatia-Slavonia. Croatia-Slavonia was an autonomous kingdom within the Lands of the Crown of Saint Stephen (Transleithania), the Hungarian part of Austria-Hungary. The region of Syrmia is today split between Croatia and Serbia. The capital of the county was Vukovar (Vukovár).

Geography
Syrmia County shared borders with other Croatian-Slavonian counties of Požega and Virovitica, the Austro-Hungarian land of Bosnia and Herzegovina, the Kingdom of Serbia, and the Hungarian counties of Bács-Bodrog and Torontál. The County stretched along the right (southern) bank of the river Danube and the left (northern) bank of the river Sava, down to their confluence. Its area was 6,866 km² around 1910.

Background
By the 13th century, two counties were formed in this region: Syrmia (in the east) and Vukovar (in the west). Syrmia County was an administrative division of the Kingdom of Hungary in the Middle Ages. This area was taken by the Ottoman Empire in 1521 and the two counties were abolished. The territory was then (in 1544) included into Ottoman Sanjak of Syrmia. The Habsburg monarchy took one part of Syrmia from the Ottomans in 1688, while the other part was taken by Habsburgs in 1718. The entire region was incorporated into the Military Frontier, which was then extended from Western Slavonia, where it stood in 1683, all the way to Transylvania.

History
Syrmia County was re-established in 1745 as part of the Kingdom of Slavonia, a Habsburg province, which was part of both the Habsburg Kingdom of Croatia and the Habsburg Kingdom of Hungary. This new county did not cover the whole of its later territory – the southern and furthest eastern parts instead passed to the Slavonian Military Frontier (and partially to the Banat Military Frontier 1849–60). The Kingdom of Slavonia was mainly inhabited by Serbs and Croats.

In 1848 and 1849, the area of the county was part of the Serbian Voivodship, a Serbian autonomous region proclaimed at the May Assembly in Karlovci. Between 1849 and 1860 the eastern part of the county was part of the Voivodeship of Serbia and Banat of Temeschwar, a separate crown land of the Austrian Empire, formally becoming part of the Neusatz District from 1854; the western part around Vukovar passed to the Slavonian Osijek County.

After 1860, Syrmia County was established again, and was reincorporated into the Kingdom of Slavonia, which was a completely separate Habsburg province at the time. In 1867, as a consequence of the Ausgleich between the Austrians and the Hungarians, the Kingdom of Slavonia was incorporated into Transleithania, the half of Austria-Hungary run from Budapest, and in the Hungarian-Croatian Settlement of 1868, it was incorporated into Croatia-Slavonia, a formally separate kingdom within the Kingdom of Hungary, which had a certain level of autonomy and was ruled by its own ban.

In 1881 the Slavonian Military Frontier was abolished; the Petrovaradin district and part of the Brod district would be merged into Syrmia County by 1886.

After World War I, the area of Syrmia County became part of the newly formed Kingdom of Serbs, Croats and Slovenes in 1918 and this was confirmed by the Treaty of Saint-Germain in September 1919. The County of Syrmia was an official administrative division of the Kingdom of Serbs, Croats and Slovenes between 1918 and 1922, and then was transformed into the Province (Oblast) of Syrmia (de facto it was carried out in  1924 ).
