Much information about his reign comes from the accounts of Portuguese travelers Domingo Paes and Fernao Nuniz. Krishna Deva Raya benefited from the able prime minister Timmarusu, who was regarded by the emperor as a father figure and was responsible for his coronation. Krishna Deva Raya was the son of Tuluva Narasa Nayaka, an army commander under Saluva Narasimha Deva Raya, who later took control of the empire to prevent its disintegration and became the founder of the Tuluva Dynasty, the third Hindu Dynasty to rule Vijayanagara. The emperor's coronation took place on the birthday of Hindu God Krishna. He built a beautiful suburb near Vijayanagara called Nagalapura.
