Arab League
22 March 1945

The Arab League (Arabic: الجامعة العربية‎ al-Jāmiʻah al-ʻArabīyah), formally the League of Arab States (Arabic: جامعة الدول العربية‎ Jāmiʿat ad-Duwal al-ʿArabīyah), is a regional organization of Arab states in and around North Africa, the Horn of Africa and Arabia. It was formed in Cairo on 22 March 1945 with six members: Kingdom of Egypt, Kingdom of Iraq, Transjordan (renamed Jordan in 1949), Lebanon, Saudi Arabia, and Syria.[3] Yemen joined as a member on 5 May 1945. Currently, the League has 22 members, but Syria's participation has been suspended since November 2011, as a consequence of government repression during the Syrian Civil War.[4]
