The flag of Palestine is very similar to the flags of several other Arab countries, particularly Jordan, Sudan, and the Arab Revolt flag of 1916. It features a tricolor of horizontal stripes in black, white, and green, with a red triangle at the hoist. This design is based on the Pan-Arab colors, which symbolize different Arab dynasties and represent Arab nationalism. The closest country flag to Palestine's is Jordan's flag, which uses the same colors and a similar design with the addition of a white star in the red triangle. The flags of Sudan and the former Arab Federation of Iraq and Jordan also share similar patterns and colors. These flags all derive their inspiration from the flag of the Arab Revolt against Ottoman rule during 1916–1918. In summary, Palestine's flag is most similar to Jordan's flag and shares its roots with other Pan-Arab flags like Sudan and the Arab Revolt flag, representing Arab unity and nationalism through the use of the same symbolic colors.
