The African Union (AU) is a continental union consisting of all 55 countries on the African continent. It was established on 26 May 2001 in Addis Ababa, Ethiopia, and launched on 9 July 2002 in South Africa, with the aim of replacing 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.

The objectives of the AU 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 Idriss Déby, President of Chad. The AU also has a representative body, the Pan African Parliament, which consists of 265 members elected by the national legislatures of the AU member states. Its president is Bethel Nnaemeka Amadi.

Other political institutions of the AU include

The AU Commission, the secretariat to the political structures, is chaired by Nkosazana Dlamini-Zuma of South Africa. On 15 July 2012, Ms. Dlamini-Zuma won a tightly contested vote to become the first female head of the African Union Commission, replacing Jean Ping of Gabon.

The main administrative capital of the African Union is in Addis Ababa, Ethiopia, where the African Union Commission is headquartered. A new headquarters complex, the AU Conference Center and Office Complex (AUCC), was inaugurated on 28 January 2012, during the 18th AU summit. The complex was built by China State Construction Engineering Corporation as a gift from the Chinese government, and accommodates, among other facilities, a 2,500-seat plenary hall and a 20-story office tower. The tower is 99.9 meters high to signify the date 9 September 1999, when the Organization of African Unity voted to become the African Union.
