The elder son, Thimma Bhupala, was assassinated within a few weeks after his father's death by an army commander loyal to the old Sangama dynasty.
He was only a teenager when he was crowned the Emperor of the Vijayanagara, and real power lay in the hands of his guardian, the imperial regent Tuluva Narasa Nayaka.
Nevertheless, the late regent's eldest son, Tuluva Vira Narasimha Raya, remained the power behind the throne due to his control of the army.
He compelled Narasimha II to name him the Dalavayi (commander-in-chief of the army) and also the Sarvadhikari ("Administrator General", effectively Regent).
Not only that, but Tuluva Narasa Nayaka had also later pacified the country, suppressed the supporters of the old Sangama dynasty, and maintained order during the minority of the usurper's two sons.
