Hoysala Empire
Before the early 14th-century rise of the Vijayanagara Empire, the Hindu states of the Deccan, the Yadava Empire of Devagiri, the Kakatiya Kingdom of Warangal, the Pandyan Empire of Madurai, and the tiny kingdom of Kampili had been repeatedly invaded by Muslims from the north, and by 1336 they had all been defeated by Alauddin Khalji and Muhammad bin Tughluq, the Sultans of Delhi. The Hoysala Empire was the sole remaining Hindu state in the path of the Muslim invasion. After the death of Hoysala king Veera Ballala III during a battle against the Sultan of Madurai in 1343, the Hoysala Empire merged with the growing Vijayanagara empire.
