rectly controlled by the Austrian emperor. Ottoman advances in the Croatian territory continued until the 1593 Battle of Sisak, the first decisive Ottoman defeat, and stabilisation of borders. During the Great Turkish War (1667–1698), Slavonia was regained but western Bosnia, which had been part of Croatia before the Ottoman conquest, remained outside Croatian control. The present-day border between the two countries is a remnant of this outcome. Dalmatia, the southern part of the border, was similarly defined by the Fifth and the Seventh Ottoman–Venetian Wars. The Ottoman wars instigated great demographic changes. Croats migrated towards Austria and the present-day Burgenland Croats are direct descendants of these settlers. To replace the fleeing Croats the Habsburgs called on the Orthodox populations of Bosnia and Serbia to provide military service in the Croatian Military Frontier. Serb migration into this region peaked during the Great Serb Migrations of 1690 and 1737–39.

In response the Royal Navy started the blockade of the Adriatic Sea leading to the Battle of Vis in 1811. The Illyrian Provinces were captured by the Austrians in 1813, and absorbed by the Austrian Empire following the Congress of Vienna in 1815.
