Yemen

The flag of Yemen is a horizontal tricolour featuring the colours (from the top of the flag to the bottom of the flag) red, white and black.

Yemen was originally two countries - North Yemen and South Yemen - each with its own flag. The flag of North Yemen was a red, white and black tricolour with a green star at its centre. The flag of South Yemen was a red, white and black tricolour with a blue triangle and red star in the hoist. Upon the unification of North Yemen and South Yemen on 22 May 1990, a new flag was adopted retaining the common elements of the two flags.

The official description of the flag of Yemen states that the colour red stands for unity and the bloodshed of martyrs, the colour white stands for a bright future and the colour black stands for the dark past.
