Narasimha Raya II became the Emperor of the Vijayanagara Empire when he was a teenager following the violent death of his father.
The elder son, Thimma Bhupala, was killed within a few weeks after his father's death by an army commander loyal to the old Sangama dynasty. This brought the second son, Narasimha, to the throne. 
Thus, Narasimha II came to the throne following the violent death of his elder brother.
