Sri Krishnadevaraya ruled the Vijayanagara empire for 21 years during the years, 1509 – 1529.
The reign of Krishnadevaraya marks “the grand climax in the development of the empire, and the successful achievement of the objects for which it was actually founded”. He was the greatest ruler of Vijayanagara and one of the most famous kings in the history of India and is considered as the greatest Hindu kuruba king to have ever lived.
