As the Turkish incursion into Europe started, Croatia once again became a border area. The Ottoman conquest in Croatia began with fall of Imotski in 1492. Croats fought an increasing number of battles and gradually lost increasing swathes of territory to the Ottoman Empire. Ottoman conquests led to the 1493 Battle of Krbava field and 1526 Battle of Mohács, both ending in decisive Ottoman victories. King Louis II died at Mohács, and in November 1526, a Hungarian parliament elected János Szapolyai as the new king of Hungary. In December 1526, another Hungarian parliament elected Ferdinand Habsburg as King of Hungary. On the other side, the Croatian Parliament met in Cetin and chose Ferdinand I of the House of Habsburg as new ruler of Croatia, under the condition that he provide protection to Croatia against the Ottoman Empire while respecting its political rights. A few years later both crown would be again united in Habsburgs hands and the union would be restored. The Ottoman Empire further expanded in the 16th century to include most of Slavonia, western Bosnia (then called Turkish Croatia) and Lika. Those territories initially was part of Rumelia Eyalet, and later was parts of Budin Eyalet, Bosnia Eyalet and Kanije Eyalet.
