The Organization of African Unity (OAU) was established in 1963 to promote unity and solidarity among African countries as well as address common challenges faced by the continent. Setting up an African High Command refers to the establishment of a unified military command for Africa, which the OAU did not succeed in achieving.

While the OAU made efforts to address various issues, including promoting peace, resolving conflicts, and fostering economic and social development, the idea of creating a centralised African military command faced challenges and was not realised. The sovereignty concerns of member states and the complexities of coordinating a unified military structure across diverse nations contributed to the failure of establishing an African High Command under the OAU.
