Answer: Vidyaranya
Notes: Harihara I and Bukka Raya I, brothers who served as commanders in the Kakatiya army, were captured by Muhammad bin Tughlaq and converted to Islam in Delhi. Under the spiritual guidance of sage Vidyaranya, they reverted to Hinduism and founded the Vijayanagara Empire in 1336. Vidyaranya, the Jagadguru of the Shringeri Sharada Peetam, advised them to establish their kingdom at a location they had identified, which became Vijayanagara. The brothers became the first rulers of the Sangama dynasty, establishing a major Hindu state in South India.
