The Father Heras theory states that Sangama brothers had a great devotion to the Karnataka deities like Virupaksha and Keshava.

[11] After the King of Warangal was defeated by Muhammad bin Tughlaq, Bukka and his brother were taken prisoners and sent to Delhi, where they both converted to Islam.

[12][13] Bukka and his brother eventually escaped, reconverted to Hinduism under the influence of the sage Vidyaranya, and founded the Vijayanagara Empire.

His son, Kumara Kampana, campaigned with him and their efforts were recorded in the Sanskrit work Madura Vijayam(also known as Veerakamparaya Charitram) written by his wife Gangambika.

Under the patronage of Bukka and other early Vijayanagar kings, a group of scholars headed by Sayana produced commentaries on the Samhitas of the four Vedas, and several of the Brahmanas and Aranyakas.
