Flag of the United Arab Emirates
It contains the Pan-Arab colors red, green, white, and black, which symbolize Arabian unity.
Flag of each emirate
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 red flags traditionally used 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.
Dubai and Ajman
Before 1952, the flag of Fujairah was plain red. In 1952, the emirate's name was added to the flag, and a red flag with a white border was adopted as an ensign. 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 in 1975.
Ras al-Khaimah and Sharjah
The Flag of Umm al-Quwain consists of a red background, a white bar at the hoist similar the flags of Ajman and Dubai, and a large white star and crescent in the center similar to the flag of Turkey.
