region today known as Vojvodina, which was then under the rule of the Kingdom of Hungary. The Hungarian kings encouraged the immigration of Serbs to the kingdom, and hired many of them as soldiers and border guards. Therefore, the Serb population of this region highly increased. During the struggle between the Ottoman Empire and Hungary, this Serb population attempted a restoration of the Serbian state. In the battle of Mohač on August 29, 1526, Ottoman Turkey destroyed the army of the Hungarian–Bohemian king Louis Jagellion, who was killed on the battlefield. After this battle Hungary broke up into three parts, and much of its former territory became part of the Ottoman Empire. Soon after the Battle of Mohač the leader of Serbian mercenaries in Hungary, Jovan Nenad "The Black", established his rule in Bačka, northern Banat, and a small part of Srem (These three regions are now parts of Vojvodina). He created an independent state, with the city of Subotica as its capital. At the peak of his power Jovan Nenad crowned himself in Subotica as the Serb emperor. Taking advantage of the extremely confused military and political situation, the Hungarian noblemen from the region joined forces against him and defeated the Serbian troops in the summer of 1527. Emperor Jovan Nenad was assassinated and his state collapsed. After the Siege of Belgrade, Suleiman I settled Serbs in the nearby Forest of Constantinople, present day Bahçeköy, called Belgrade forest. Austria and Serbia European powers, and Austria in particular, fought many wars against the Ottoman Empire, relying on the help of the Serbs who lived under Ottoman rule. During the Austro-Turkish War (1593–1606), in 1594, the Serbs staged an uprising in Banat, the Pannonian part of Turkey. Sinan Pasha retaliated by burning the remains of Saint Sava, the most sacred Serbian saint. Serbs created another center of resistance in Herzegovina, but when peace was signed by Turkey and Austria, they were abandoned to Turkish retaliation. This sequence of events became usual in the centuries that followed. The Great War between Ottomans and the Holy League The Great War between Ottomans and the Holy League took place from 1683 to 1699. The Holy League was created with the sponsorship of the Pope and included Austria, Poland and Venice. These three powers incited the Serbs to rebel against the Ottoman authorities, and soon uprisings and guerrilla warfare spread throughout the western Balkans, ranging
