Commission de l'Union africaine
The African Union was formed as a successor to the Organization 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. During the February 2009 Union meeting headed by former Libyan leader Gaddafi, it was resolved that the African Union Commission would become the African Union Authority.
