24 April 1512
The prince who unseated his father
Under heavy pressure from his son Selim, Bayezid II was forced to give up the throne; Selim became the ninth Ottoman ruler on 24 April 1512. His first task was to secure his throne: his elder brother Prince Ahmed was defeated and killed on the plain of Yenişehir on 15 April 1513. The next target was the Safavid Shah Ismail, seen as the greatest threat because of his propaganda in Anatolia and the revolts of his followers. On the map, the Safavids lie to the east and the Mamluk Sultanate to the south.
