The Battle of Mohács was fought on 29 August 1526 near Mohács, Kingdom of Hungary, between the forces of the Kingdom of Hungary and its allies, led by Louis II, and those of the Ottoman Empire, led by Suleiman the Magnificent. The Ottoman victory led to the partition of Hungary for several centuries between the Ottoman Empire, the Habsburg monarchy, and the Principality of Transylvania. Further, the death of Louis II as he fled the battle marked the end of the Jagiellonian dynasty in Hungary and Bohemia, whose dynastic claims passed to the House of Habsburg.
The Siege of Vienna, in 1529, was the first attempt by the Ottoman Empire to capture the city of Vienna in the Archduchy of Austria, part of the Holy Roman Empire. Suleiman the Magnificent, sultan of the Ottomans, attacked the city with over 100,000 men, while the defenders, led by Niklas Graf Salm, numbered no more than 21,000. Nevertheless, Vienna was able to survive the siege, which ultimately lasted just over two weeks, from 27 September to 15 October, 1529.

The Ottoman–Habsburg wars were fought from the 16th to the 18th centuries between the Ottoman Empire and the Habsburg monarchy, which was at times supported by the Kingdom of Hungary, Polish–Lithuanian Commonwealth, and Habsburg Spain. The wars were dominated by land campaigns in Hungary, including Transylvania and Vojvodina, Croatia, and central Serbia.
The Hungarian Civil War or campaign of 1527–1528 was launched by Ferdinand I, Archduke of Austria and King of Hungary and Bohemia and his Hungarian followers against the Ottoman Turks. Following the Battle of Mohács, the Ottomans were forced to withdraw as events elsewhere in their now massive Empire required the Sultan's attention. Seizing upon their absence, Ferdinand I attempted to enforce his claim as King of Hungary. In 1527 he drove back the Ottoman vassal John Zápolya and captured Buda, Győr, Komárom, Esztergom, and Székesfehérvár by 1528. Meanwhile, the Ottoman Sultan, Suleiman the Magnificent, took no action at this stage despite the pleas of his vassal.
The Habsburg monarchy and the Ottoman Empire waged a series of wars on the territory of the Kingdom of Hungary and several adjacent lands in Southeastern Europe from 1526 to 1568. The Habsburgs and the Ottomans engaged in a series of military campaigns against one another in Hungary between 1526 and 1568. While overall the Ottomans had the upper hand, the war failed to produce any decisive result. The Ottoman army remained very powerful in the open field but it often lost a significant amount of time besieging the many fortresses of the Hungarian frontier and its communication lines were now dangerously overstretched. At the end of the conflict, Hungary had been split into several different zones of control, between the Ottomans, Habsburgs, and Transylvania, an Ottoman vassal state. The simultaneous war of succession between Habsburg-controlled western "Royal Hungary" and the Zápolya-ruled pro-Ottoman "Eastern Hungarian Kingdom" is known as the Little War in Hungary.
The Hungarian–Ottoman wars were a series of battles between the Ottoman Empire and the medieval Kingdom of Hungary.
