The Kuwait flag was adopted on September 7th 1961 after Kuwait gained it's independance from Great Britain on June 19th 1961.

The flag of kuwait consists of three horizontal stripes and a black trapezium on it's side. The three coloured stripes are green, white and red.

The colours meaning came from a poem by Safie Al-Deen Al-Hali:

White are our deeds
Black are our battles
Green are our lands
Red are our swords

The flag was replaced after Kuwait was invaded by Iraq in August 1990, and was restored when Kuwait was liberated in February 1991.
