It was established in 2002 to succeed the Organisation of African Unity (OAU) and aims to promote unity, cooperation, and development among African nations.

Addis Ababa was chosen as the headquarters due to its historical significance in Pan-African movements and its central location within Africa. The city hosts the AU's main administrative buildings, including the Conference Center and Office Complex, which serves as the venue for AU summits and meetings.
