1505–1658. The Portuguese first encountered the Ceylonese kingdom of
Kotte, with whom they signed a treaty. Portuguese Ceylon was established
through the occupation of Kotte and the conquest of surrounding Sinhalese
kingdoms. In 1565 the capital of Portuguese Ceylon was moved from Kotte
friction with the Sinhalese people.
Eventually, the Ceylonese sought help from the Dutch Empire in their struggle
for liberation. The Dutch Empire initially entered into agreement with the
Kingdom of Kandy. After the collapse of the Iberian economy in 1627, the
Dutch-Portuguese War saw the Dutch conquest of Portugal's Asiatic colonies.
Eventually, Portugal's Ceylonese territories were ceded to the Netherlands.
Nevertheless, there remain elements of Portuguese culture in Sri Lanka today
from this colonial period.
