Котте
The Kingdom of Kotte had been the major power in western Sri Lanka since its foundation in the early 15th century; under Parakaramabahu VI, the polity has been the last to unite the entirety of the island of Sri Lanka under one crown. By 1467, however, the Jaffna Kingdom to the north had asserted its independence. In 1505 the first Portuguese arrived in Sri Lanka; by 1518 a large fleet of Portuguese ships had landed at Colombo and begun to construct a fort known as Santa Bárbara. To the east, the client kingdom of Kandy was by this time operating with a considerable degree of independence as well.
