The flag is a tricolour of three equal horizontal stripes (black, white, and green from top to bottom) overlaid by a red triangle issuing from the hoist. These are the Pan-Arab colours. The flag is almost identical to that of the Baath Party, and extremely similar to the flags of Jordan, and Western Sahara, all of which draw their inspiration from the Arab Revolt against Ottoman rule (1916–1918). Prior to being the flag of Palestine, it was the flag of the short lived Arab Federation of Iraq and Jordan. The flag of the Arab Revolt had the same graphic form, but the colours were arranged differently (white on the bottom, rather than in the middle).
