The flag of East Timor (also known as Timor-Leste) was adopted in 2002. It is the same as the 1975 flag.
At midnight on May 19, and during the first moments of Independence Day, 20 May 2002, the United Nations Flag was lowered, and the flag of an independent East Timor was raised.
As per the Constitution of the Democratic Republic of Timor-Leste, the yellow triangle represents "the traces of colonialism in East Timor's history". The black triangle represents "the obscurantism that needs to be overcome"; the red base of the flag represents "the struggle for national liberation"; the star, or "the light that guides", is white to represent peace.
"The national flag is rectangular and is formed by two isosceles triangles, the bases of which are overlapping. One triangle is black, and its height is equal to one-third of the length overlapped to the yellow triangle, whose height is equal to half the length of the Flag. In the center of the black triangle, there is a white star of five ends, meaning the light that guides. The white star has one of its ends turned towards the left side end of the flag. The remaining part of the flag is red."
