The flag of the United Arab Emirates has a vertical red band taking up the left hoist section of the flag, then red, white and black horizontal bands across the rest. These colors are the typical ones representing Arab nationalism. This flag was adopted in December of 1971. As there are seven emirates in the UAE, there are also flags representing these emirates. There are four unique flags used by the emirates. The emirate of Fujairah uses the UAE flag as its own flag too. The emirates of Dubai and Ajman and the emirates of Ras al-Khaimah and Sharjah use the same unique flag.
The emirate of Abu Dhabi uses a red rectangle with a small white rectangle in the left hand corner of the flag. The emirates of Dubai and Ajman use a red rectangle flag with a white vertical band in the left hand hoist section of the flag. The emirate of Fujairah uses the UAE flag, but previously used a plain red flag before 1952. After 1952, until the UAE came into being, the center part of the flag was the Arabic words for Fujairah in white. The emirates of Ras al-Khaimah and Sharjah use a white rectangle flag with a red rectangle in the center. The emirate of Umm al-Quwain uses a mostly red flag with a white vertical band in the left hand hoist area. In the center is a white crescent with a five-pointed star. The crescent is facing the left and is slightly thicker than usual flag depictions of the design.
There are two variant flags of the UAE. The first is an alternative civil ensign and is a red rectangle with a small version of the official UAE flag in the left upper corner. The flag of the President of the UAE is the official flag with the UAE coat of arms in the center. This coat of arms is in a shield shape with a golden eagle in the center. A circular version of the UAE flag is in the center of the eagle and an inscription in Arabic is on the bottom red banner in white.
