The transformation from the Organisation of African Unity (OAU) to the African Union (AU) represents a quantum leap in the Pan-African joint action: the OAU, ever since its inception in 1963, focused on promoting solidarity and unity among the peoples of Africa to eradicate all forms of colonialism and gain Pan-African political independence. Africa, despite the liberation of all the peoples of the continenet, has encountered challenges right after the eradication of colonialism due to the weakness of government institutions, disputes, especially the internal ones, corruption, economic mismanagement and deteriorating social conditions in some countries.
