Hoysala Empire
Aiyangar opines that since the Kakatiya dynasty collapsed about 20 years before the demise of Veera Ballala III of Hoysala Empire in 1342 CE, and Hosapattana was established as a second capital by Veera Ballala III (which eventually became the capital of the Vijayanagara Empire) it would be impossible for Harihara, the founder of fledgling empire to attain such a high position in a short time without having close ties to Hoysala Empire.
