Hongrie ottomane
After the seizure of Buda by the Turks in 1541, west and north Hungary recognized a Habsburg as king ("Royal Hungary"), while the central and southern counties were occupied by the Sultan ("Ottoman Hungary"), and the east became the Principality of Transylvania. The vast majority of the seventeen and nineteen thousands Ottoman soldiers in service in the Ottoman fortresses in the territory of Hungary were Orthodox and Muslim Balkan Slavs instead of ethnic Turkish people. Southern Slavs were also acting as akinjis and other light troops intended for pillaging in the territory of present-day Hungary.
