Hungarian–Ottoman Wars

The Hungarian–Ottoman wars (Hungarian: Magyar–török háborúk, Turkish: Macaristan-Osmanlı Savaşları) were a series of battles between the Ottoman Empire and the medieval Kingdom of Hungary. Following the Byzantine Civil War, the Ottoman capture of Gallipoli, and the inconclusive Battle of Kosovo, the Ottoman Empire was poised to conquer the entirety of the Balkans. It also sought and expressed desire to expand further north into Central Europe, beginning with the Hungarian lands.

The Ottomans won a significant victory at the Battle of Varna in 1444, but suffered a defeat at the 1456 Siege of Belgrade. One notable figure of this period was Vlad the Impaler, who, with limited Hungarian help, resisted Ottoman rule until the Ottomans placed his brother, Radu the Handsome, on the throne of Wallachia. Ottoman success was once again halted at Moldavia due to Hungarian intervention, but the Turks finally succeeded when Moldavia and then Belgrade fell to Bayezid II and Suleiman the Magnificent, respectively. In 1526 the Ottomans crushed the Hungarian army at the Battle of Mohács, where King Louis II of Hungary and more than 20,000 of his soldiers died.

Following this defeat, the eastern region of the Kingdom of Hungary (the Eastern Hungarian Kingdom and later Principality of Transylvania) became an Ottoman tributary state, constantly engaged in civil war with Royal Hungary. The war continued with the Habsburgs now asserting primacy in the conflict with Suleiman and his successors. The northern and most of the central parts of Hungary managed to remain free from Ottoman rule, but the Kingdom of Hungary, the most powerful state east of Vienna under Matthias I, was now divided and constantly threatened by Ottoman ambitions in the region.
