While post-colonial atrocities were generally perpetrated by states within nations, Slavery affected peoples across the continent of Africa, in diverse and enduring ways. In the loss of lives and dehumanisation it entailed it profoundly undermined resistance to colonization and the prospects for development. It negatively affected relations between Africans, and laid the foundation for abuse and inequalities experienced by Africans internationally. The AU has a responsibility to remember this atrocity committed against, and sometimes also by, Africans. The institution also inherits from the OAU the pan-Africanist sentiments founded in part upon the memory of slavery and the bonds between Africans and the diaspora.
