United Arab Republic – Wikipedia

The United Arab Republic (UAR; Arabic: الجمهورية العربية المتحدة ‎ al-Jumhūrīyah al-‘Arabīyah al-Muttaḥidah) was a sovereign state in the Middle East from 1958 to 1971. It was initially a political union between Egypt (including the occupied Gaza Strip) and Syria from 1958 until Syria seceded from the union after the 1961 Syrian coup d’état, leaving a rump state.
