Śrī Kṛṣṇa Deva Rāya also known as Krishna Deva Raya (IAST Kṛṣṇa Deva Rāya) was an Emperor of the Vijayanagara Empire who reigned from 1509–1529 CE. He is the third ruler of the Tuluva Dynasty. Presiding over the empire at its zenith, he is regarded as an icon by many Indians. Emperor Krishna Deva Raya earned the titles Andhra Bhoja, Mooru Rayara Ganda (lit, "King of three Kings") and Kannada Rajya Rama Ramana (lit, "Lord of the Kannada empire"). He became the dominant ruler of the peninsula of India by defeating the Sultans of Bijapur, Golconda and the Raja of Odisha. The great south Indian mathematician Nilakantha Somayaji also lived in the Empire of Krishnadevaraya.[1] Indeed, when the Mughal Babur was taking stock of the potentates of India, KDR was rated the most powerful and had the most extensive empire in the subcontinent.
