Veera Ballala IV resided over a declining Hoysala kingdom, and was in constant war with the Turko-PersianMadurai Sultanate and an upcoming Vijayanagara Empire. He was unable to check the advance of the Sangama brothers of Vijayanagara. (Harihara, Bukka, Kampa I, Marappa and Muddappa). It did not help that Virupaksha Ballala was an incompetent ruler.[2] All the several chiefs, who had served his capable father Veera Ballala III, now took advantage of Virupaksha Ballala's weakness, grabbed the opportunity and started declaring their independence.[3] The finest Hoysala soldiers had been killed in the war against Turko-Persian Sultan of Madurai. He had given away his entire treasure to Ghiyas-ud-din, the Turko-Persian Sultan of Madurai in the vain hope of releasing his father. Even his general and cousin Ballappa Dandanayaka, who had served him and his father Veera Ballala III loyally now deserted him. In spite of all these difficulties, he still put up a stiff resistance and it was only after a continuous struggle of 6 years (A.D. 1346) that the Vijayanagara rulers were able to conquer the whole of the Hoysala kingdom.[4][5]
The Kadambas, who were ruling over Banavasi, on the coast of Konkan gave shelter to Virupaksha Ballala. To defeat them, Harihara sent his brother Marappa. The latter defeated the Kadamba ruler and annexed his territory.[4][5]
Death
Veera Ballala IV was captured in a battle fought against the Turko-PersianMadurai Sultanate. He was flayed and then slain, just as his father was. This happened in c. 1346. This was the end of the rule of the Hoysalas.[6][1][7]
