During the 1350‘s due to periodic invasions of the western region of Sri Lanka by the northern based Jaffna kingdom, many regions had begun to pay tribute and taxes to the Arya Chakaravarthi kings. The third member of the family to figure in historical accounts, known only as Alakesvara, was a minister of the local king Vikramabahu III of Gampola fortified a marshy region around present day Colombo region, on the marshes to the south of the Kelani River. He called the fortress Jayewardhanapura, and the area became known as "Kotte", "The fort". By 1369 Alakesvara drove out the tax collectors and attacked the encampments of soldiers from Jaffna kingdom who attempted to invade the Sinhalese kingdoms at Chilaw and Negombo killing a large number of them and forcing the rest to retreat. The Arya Chakaravarthi launched a second invasion attempt during the reign of Bhuvanaikabahu V of Gampola, landing in the southern kingdom by land and sea. Although the king initially fled his capital, his army defeated the force that approached along the ground in Matale. Alakeshwara simultaneously attacked the troops that arrived by sea, routing them at Dematagoda, and destroying their ships at Panadura.
