East Timor () was a de facto province of Indonesia that existed between 1976 and 1999 during the Indonesian occupation of East Timor. Its territory corresponded to the previous Portuguese Timor and to the present-day independent country of Timor-Leste. From 1702 to 1975, East Timor was an overseas territory of Portugal, called "Portuguese Timor". In 1974, Portugal initiated a gradual decolonisation process of its remaining overseas territories, including Portuguese Timor. During the process, a civil conflict between the different Timorese parties erupted. In 1975, Indonesia invaded East Timor and in 1976, it formally annexed the territory, declaring it as its 27th province and renaming it "Timor Timur". The United Nations, however, did not recognise the annexation, continuing to consider Portugal as the legitimate administering power of East Timor. Following the end of Indonesian occupation in 1999, as well as a United Nations administered transition period, East Timor became formally independent of Portugal in 2002 and adopted the official name of Timor-Leste. Background From 1702 to 1975, East Timor was an overseas territory of Portugal, lately being officially the Portuguese overseas province of Timor, usually referred as "Portuguese Timor". Following the "Carnation Revolution" of 1974, the new Government of Portugal initiated a gradual decolonization process of its overseas territories, including Portuguese Timor. During the process, a civil conflict between the several Timorese political parties erupted, with the left-wing Revolutionary Front for an Independent East Timor (Fretilin) prevailing and being able to control the capital Dili, obliging the Portuguese governor and his staff to move his seat to the Atauro Island. On the 28 November 1975, Fretilin unilaterally declared the independence of the then Portuguese Timor, calling it República Democrática de Timor-Leste (Portuguese for "Democratic Republic of East Timor"). Portugal did not however recognize that independence, with the Portuguese governor continuing to be present and formally administering the province from Atauro, although having a limited de facto authority over the remaining territory of East Timor. Nine days later, Indonesia began the invasion of the majority of the territory of East Timor. Following the invasion, the Portuguese governor and his staff left Atauro aboard two Portuguese warships. As a statement of Portuguese sovereignty, Portugal maintained those warships patrolling the waters around East Timor until May 1976. On 17 July 1976, Indonesia formally annexed East Timor as its 27th province and changed its official name to Timor Timur, the Indonesian translation of "East Timor".
