national flag consisting of a red field with a black triangle at the hoist overlapping a yellow triangle and bearing a white, five-pointed star. The flag's width-to-length ratio is 1 to 2.

The flag is based on a design used by the Revolutionary Front of Independent East Timor (Fretilin), the main group opposing Indonesia's takeover of East Timor in 1975–76. That flag consisted of a striped red-yellow-red field with a black canton along the hoist bearing a white star. Following Indonesia's withdrawal in 1999, East Timor was administered by the UN, and the UN flag flew over it. The new national flag was adopted on May 20, 2002, when East Timor achieved full sovereignty. The black represents more than four centuries of colonial repression, the yellow the struggle for independence, and the red the suffering of the East Timorese people. The white star symbolizes hope for the future.
