Each of the seven emirates within the United Arab Emirates has its own flag, except for Fujairah, which uses the federal flag as state flag too.
The flags are derived from the traditional red flags used traditionally by the different Arab emirates around the Persian Gulf. Under the protection of the British Empire from 1820, it was decided to add a white field at the hoist of the flag. The same basic pattern can be seen in the flag of Bahrain and the flag of Qatar, emirates who opted not to join the UAE when it was created in the 1970s.
The federal flag is also used as the state's flag in Fujairah
Flag of Fujairah from 1952 until circa 1975
From 1902 until 1952, the flag of Fujairah was plain red without any other charge on it at all. Unlike the other Trucial states, Fujairah has no coastline on the Perisan Gulf, which could explain the absence of a white field. In 1952, the Sheikh included the name of the emirate, in white, on the red flag, and thus using the same red and white colours as the neighouring Trucial states. This continued to be the official flag until Sheikh Hamad bin Mohammed Al Sharqi abolished the red flag and adopted the Federal flag as the flag of Fujairah.
