July 26, 1509 Krishnadevaraya became emperor of the Vijayanagara Empire. 
He was the third ruler of the Tuluva dynasty in south India from 1509 to 1529 and is is regarded as one of India’s most powerful rulers.

Although Krishnadevaraya ruled Vijayanagara for 20 years, between 1509 and 1529, his legacy has over the centuries transcended the human scale, enabling him to acquire semi-divine proportions in the collective memory of Southern India. There are roads, universities, even entire administrative units of states named after the king (why, the University of Wisconsin-Madison has instituted a Krishnadevaraya Chair at the School of Languages and Culture of Asia, currently occupied by Velcheru Narayana Rao). ‘Raya’: Srinivas Reddy’s biography of Krishnadevaraya is a love letter to the king from South India (scroll.in)

If you’ve never looked at Indian stamps, take the opportunity now. They have some brilliant designers and a history that goes so deep, there is no end to themes they cover. India 2023 (bittergrounds.com) is a good staring place. Be warned, my posts are erratic for India because the post office website can be a bit irritating at times. Sorry to fans from India. I’ll try harder. 
Cheers
