Adil Shah died in 1509-10 while engaged in an 'annual jihad', possibly a plundering expedition, against the Vijayanagara empire to the south. The practice was initiated by Sultan Mahmood Shah Bahmani II in 1501, in which all the Bahmani chieftains participated. However, in 1509, Krishnadevaraya ascended the throne of Vijayanagara. He countered the Bahmani expedition at a location called Dewani (unidenfied) and decisively defeated it. The Sultan was thrown off the horse and had to be carried away from the battlefield. Raya then pursued the retreating army of Bijapur. Adil Shah turned around to give him battle at Koilkonda, in which he was killed.
