Flag_of_the_Arab_Federation
In 1958, in response to the merger of Egypt and Syria in the United Arab Republic, the two Hashemite kingdoms of Iraq and Jordan established the Arab Federation, a confederation of the two states. According to the 7th article of the Federation convention, the Arab revolt flag was to be the official flag of the Union.[1][2] The union lasted less than six months, being terminated by the Iraqi Revolution of 1958 in July.
