The Portuguese were the first Europeans to establish themselves in Timor; their claim to the island was disputed by the Dutch, who arrived in 1613. By a treaty of 1859, modified in 1893 and finally made effective in 1914, the border between the Dutch and Portuguese territories was settled. In World War II, Timor was occupied (early 1942) by the Japanese. With the creation of the Republic of Indonesia in 1950, Dutch Timor became Indonesian territory and is now part of Nusa Tenggara Timur province.
In 1975, Portuguese Timor declared itself independent as East Timor. Indonesia invaded, however, and annexed the region. Sporadic guerrilla warfare continued into 1999, when Indonesia agreed to permit a referendum in which voters chose independence. Pro-Indonesian militias and the army subsequently engaged in a campaign of terror and brutality, but under international pressure Indonesia asked for UN peacekeepers, and, following a period of transitional UN administration, East Timor became independent in 2002.
