Which of the following groups advocated political union of African states?

The group that advocated for the political union of African states was the Casablanca Group. This group was formed in 1961 and included the leaders of several African countries, including Ghana, Guinea, Mali, Morocco, and Egypt. The Casablanca Group was committed to the idea of African unity and believed that the best way to achieve this was through the formation of a single, united African state. The group's leaders saw the political union of African states as a way to overcome the legacy of colonialism and promote economic and social development on the continent. They believed that a united Africa would be stronger and more able to resist the influence of outside powers, and that it would be better able to negotiate with other nations on a more equal footing. However, the idea of a united African state was not universally accepted, and there were other groups advocating for a more gradual approach to integration. Despite this, the Casablanca Group's advocacy for African unity helped to inspire a sense of pan-Africanism across the continent and played an important role in the eventual formation of the African Union in 2002.
