Why was the OAU transformed into the AU?

The Organization of African Unity (OAU) was transformed into the African Union (AU) in 2001 to address the continent's evolving political, social, and economic challenges more effectively. The AU aimed to enhance regional integration, promote peace and security, and foster sustainable development in Africa. It also sought to strengthen the continent's capacity to address issues such as human rights violations and conflicts, which were inadequately managed under the OAU framework. This transformation reflected a shift towards a more proactive and comprehensive approach to African unity and cooperation.
