The East African Federation (EFA) is a proposed political union of the seven sovereign states of the East African Community in the African Great Lakes region – Burundi, the Democratic Republic of the Congo, Kenya, Rwanda, South Sudan, Tanzania and Uganda – as a single federated sovereign state.
The EFA would be the biggest and most populous as well as the 4th largest GDP in Africa, and all of them have adopted Swahili as a national language, though different languages, religions, and ethnicities exists in the EFA.
