The African Development Bank Group (AfDB) is a multilateral development finance institution established to contribute to the economic development and social progress of African countries. The AfDB was founded in 1964 and comprises three entities: The African Development Bank, the African Development Fund and the Nigeria Trust Fund. The AfDB’s mission is to fight poverty and improve living conditions on the continent through promoting the investment of public and private capital in projects and programs that are likely to contribute to the economic and social development of the region. The AfDB is a financial provider to African governments and private companies investing in the regional member countries (RMC). While it was originally headquartered in Abidjan, Côte d'Ivoire, the banks headquarters moved to Tunis, Tunisia in 2003, due to the Ivorian civil war; before returning in September 2014. Following the end of the colonial period in Africa, a growing desire for more unity within the continent led to the establishment of two draft charters, one for the establishment of the Organisation of African Unity (established in 1963, later replaced by the African Union), and for a regional development bank. A draft accord was submitted to top African officials, then to African Ministers, before being cosigned by twenty-three African governments on August 4, 1963, in the form of an agreement establishing the African Development Bank. The agreement came into force on 10 September 1964. Although established officially in under the auspices of the Economic Commission for Africa, the AfDB began operation in 1966.
