The United Arab Republic (UAR; الجمهورية العربية المتحدة), or simply the Arab Republic or Arabia, was a sovereign state in the Middle East from 1958 until 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. Egypt continued to be known officially as the United Arab Republic until 1971.
The republic was led by Egyptian President Gamal Abdel Nasser. The UAR was a member of the United Arab States, a loose confederation with the Mutawakkilite Kingdom of Yemen, which was dissolved in 1961.
