Бахмани
In the south, the Bahmani Sultanate, which was established either by a Brahman convert or patronised by a Brahman and from that source it was given the name "Bahmani", was the chief rival of the Vijayanagara, and frequently created difficulties for the Vijayanagara. In the early 16th century Krishnadevaraya of the Vijayanagar Empire defeated the last remnant of Bahmani Sultanate power. After which, the Bahmani Sultanate collapsed, resulting it being split into five small Deccan sultanates. In 1490, Ahmadnagar declared independence, followed by Bijapur and Berar in the same year; Golkonda became independent in 1518 and Bidar in 1528. Although generally rivals, they did ally against the Vijayanagara Empire in 1565, permanently weakening Vijayanagar in the Battle of Talikota.
