Habsburg–Ottoman wars in Hungary (1526–1568)
Habsburg–Ottoman wars in Hungary, from 1526 to 1568, were wars between the Habsburg Monarchy and the Ottoman Empire, waged on the territory of the Kingdom of Hungary and several adjacent lands in Southeastern Europe. 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 Litte War in Hungary.
