The temple witnessed a major expansion during the rule of the Vijayanagar kings like Sadasiva Raya, Sriranga Raya and Venkatapati Raya II (16th Century). Many sub-shrines and pillared pavilions (mandapas) like the Tiruvaimozhi Mandapa were added.
Rulers and landed aristocracy vied with each other in their patronage of composers and musicians and the cyclical patronage of royal Courts at Vijayanagar, Tanjore, Trivandrum , Pudukottai, Mysore , Ettayapuram, etc. In Preface
The dasara celebrations, on the lavish scales now maintained, date from the beginning of the 17th century, when Raja Wodeyar came to the throne of Mysore after Sri Rangaraja, as descendent of the Vijayanagar Princes. With his ascent also dates the use of the famous throne by the Maharaja, during the festival. Raja Wodeyar who became the king of Mysore at the beginning of the 17th century, celebrated the dasara festival on a royal scale, and after him, year after year the Dasarz has gained in splendor, entertainment and attractiveness.Usha Sharma
