Vishnuvardhana (r.1108–1152 CE) was a king of the
Hoysala Empire in what is today the modern state of
Karnataka, India. He ascended the Hoysala throne after the death of his elder brother Veera Ballala I in c.1108. Originally a follower of Jainism and known as Bitti Deva, he came under the influence of the Hindu philosopher
Ramanujacharya, converted to Hindu
Vaishnavism and took the name "Vishnuvardhana". Vishnuvardhana took the first steps in creating an independent Hoysala Empire in
South India through a series of battles against his overlord, the
Western Chalukya King
Vikramaditya VI, and the
Chola Empire to the south. He recovered parts of Gangavadi province (modern southern Karnataka) from the hegemony of the Cholas in the battle of Talakad, and parts of Nolambavdi. According to historian Coelho, the Hoysalas gained the dignity of a kingdom due to the efforts of Vishnuvardhana, whose rule was packed with "glorious" military campaigns. According to historians Sen, Chopra et al., and Sastri, Vishnuvardhana was a "great soldier" and an "ambitious monarch".
