As a student in Morocco, I wanted to honour this country that welcomed me and helped me to pursue my higher education. This study, about Morocco, has for theme the reintegration of Morocco in the African Union, being of very recent topicality was the subject of my thesis. It deals with the geographical situation of Morocco, its assets and the causes of its exit from the Organisation of African Unity (OAU) decided by His Majesty the late King Hassan II on 12 November 1984. As well as the reintegration of Morocco into the African Union (AU) during the 28th summit of the Conference of Heads of State and Government in January 2017 in Addis Ababa, Ethiopia, bringing together 54 African countries, 39 of which voted for this reintegration. Finally, the 1500 agreements concluded between Morocco and some African countries.
