A succession crisis emerged upon Narendrasinha's death in 1739. The king had one son – Unambuve Bandara – by a Sinhalese consort. However, succession to the Kandyan throne was reserved exclusively for those of kshatriya ancestry on both their mother and father's side, and Unambuve's mother had been of a lower caste. With the support of the bhikku Weliwita Sarankara, the crown passed to the brother of one of Narendrasinha's senior wives, a member of the Telugu-speaking and Tamil-speaking Nayak house from southern India. He was crowned Sri Vijaya Rajasinha later that year. The Nayak Kings were of Telugu origin who practiced Shaivite Hinduism and were patrons of Theravada Buddhism. The Nayak rulers played a huge role in reviving Buddhism in the island. They spoke Tamil, which was also used as the court language in Kandy alongside Sinhala.
