Flag of Oman
|Design||A horiztonal tricolour of white, red and green; with a vertical red stripe at the hoist, charged with the National emblem of Oman. |
Until 1975, Oman used the plain red banner of the indigenous people. In 1970, the Sultan introduced a complete new set of national flags. Bands of green and white were added to the fly, and the national emblem, the badge of the Albusaidi Dynasty, was placed in the canton. Between 1970 and 1995, the size of the middle band of the triband was slimmer than the other two, making up approximately one fifth of its height, the other bands two-fifths. 
White has been associated historically with the Imam, the religious leader of Oman and at times the political rival to the ruling Sultan. It also symbolizes peace. Green is traditionally associated with the Jabal al Akdar, or "Green Mountains", which lie toward the north of the country. Red is a common color in Gulf state flags. The national emblem is said to date back to the 18th century. This depicts crossed swords over a khanjar, a traditional curved dagger.
