The Democratic Republic of Timor-Leste, commonly known as East Timor, is an island nation in Southeast Asia, consisting of the eastern half of the island of Timor, the nearby islands of Atauro and Jaco, and Oecussi-Ambeno, a political exclave of East Timor situated on the western side of the island, surrounded by West Timor. Formerly controlled by neighbouring Indonesia, which annexed it as a province in 1975, East Timor broke away in 1999 and achieved full independence on May 20, 2002. When East Timor joined the United Nations in 2002, it decided to be officially referred to by its Portuguese name, Timor-Leste, as opposed to its English name. 90% of its population are Roman Catholics. It is one of only two majority Roman Catholic countries in Asia, the other being the Philippines.
