The African Union (abbreviated AU in English, and UA in its other official languages) is a union consisting of 54 African states. The only all-African state not in the AU is Morocco. Established on 9 July 2002, the AU was formed as a successor to the Organisation of African Unity (OAU). The most important decisions of the AU are made by the Assembly of the African Union, a semi-annual meeting of the heads of state and government of its member states. The AU's secretariat, the African Union Commission, is based in Addis Ababa, Ethiopia.

Among the objectives of the AU's leading institutions are:

The African Union is made up of both political and administrative bodies. The highest decision-making organ is the Assembly of the African Union, made up of all the heads of state or government of member states of the AU. The Assembly is chaired by Yayi Boni, president of Benin, elected at the 18^thordinary meeting of the Assembly in January 2012. The AU also has a representative body, the Pan African Parliament, which consists of 265 members elected by the national parliaments of the AU member states. Its president is Idriss Ndele Moussa.
