The flag of Jordan, officially adopted on 16 April 1928, is based on the 1916 flag of the Arab Revolt against the Ottoman Empire during World War I.

[1] The flag consists of horizontal black, white, and green bands that are connected by a red chevron.

The red chevron represents the Hashemite dynasty, and the Arab Revolt.

The star stands for the unity of the Arab people;[4] its seven points refer to the seven verses of Al-Fatiha.

Notice that, given the proportions of height and width of the red chevron, its sides are coincident with the diagonals of the flag.
