Selim I
Bayezid II had faced a revolt from his own son Selim (who succeeded as Selim I), in the final years of his rule. Unlike his father, Selim, then still a prince, disliked his father's appeasement policies towards the Safavids. When Selim I thus ascended the throne in 1512, things changed drastically. Tensions rose, which eventually led to the Battle of Chaldiran in 1514.
