The kingdom's grip on the region was weak, and by 1370 it was forced to surrender it to Harihara I of the Vijayanagara Empire. The Vijayanagara monarchs held on to the territory until 1469 when it was appropriated by the Bahmani sultans of Gulbarga. After that dynasty crumbled, the area fell into the hands of the Adil Shahis of Bijapur, who established as their auxiliary capital the city known under the Portuguese as Velha Goa (or Old Goa).[26]
