The East African Federation (Swahili: Shirikisho la Afrika Mashariki) is a proposed political union of the six sovereign states of the East African Community – Burundi, Kenya, Rwanda, South Sudan, Tanzania and Uganda – as a single federated sovereign state. In September 2018 a committee was formed to begin the process of drafting a regional constitution. At 2,467,202 square kilometres (952,592 sq mi), the East African Federation would be the largest country in Africa & 10th-largest in the world.

The Economic Community of West African States, also known as ECOWAS, is a regional economic union of fifteen countries located in West Africa. Collectively, these countries comprise an area of 5,114,162 km2 (1,974,589 sq mi), and in 2015 had an estimated population of over 349 million. As of February 2017, ECOWAS has 15 member states; eight of these are French-speaking, five are English-speaking, and two Portuguese-speaking.
