The 1978 Arab League summit was held on November 2 in Baghdad as the 9th Arab League Summit. The summit came in the aftermath of the Egypt's Anwar Sadat's unilateral peace treaty with Israel. Arab leaders convened in Baghdad in the absence of Egypt and decided to expel it from the Arab League. Consequently, the secretariat of the League was moved out of its Cairo headquarters to Tunis. This decision was reversed in the 1980s after president Hosni Mubarak ascended to power.
