In 1958, Egypt and Syria formed a sovereign union known as the United Arab Republic. The union was short-lived, ending in 1961 when Syria seceded, thus ending the union. During most of its existence, the United Arab Republic was also in a loose confederation with North Yemen (the Mutawakkilite Kingdom of Yemen) known as the United Arab States.
