The United States of Africa is a hypothetical concept of a federation of some or all of the 54 sovereign states and two disputed states on the continent of Africa. The concept takes its origin from Marcus Garvey's 1924 poem "Hail, United States of Africa". Origins The idea of a multinational unifying African state has been compared to various medieval African empires, including the Ethiopian Empire, the Ghana Empire, the Mali Empire, the Songhai Empire, the Benin Empire, the Kanem Empire and other historic nation states. During the late 19th and early 20th century the majority of African land was controlled by various European empires, with the British controlling around 30 percent of the African population at its peak. The term "United States of Africa" was mentioned first by Marcus Garvey in his poem Hail, United States of Africa in 1924. Garvey's ideas and formation systems deeply influenced former Africa leaders and the rebirth of the African Union. 2009–2011 proposals In February 2009, upon being elected chairman of the 53-nation African Union in Ethiopia, Gaddafi told the assembled African leaders: "I shall continue to insist that our sovereign countries work to achieve the United States of Africa."

Other African leaders stated they would study the proposal's implications, and re-discuss it in May 2009. The focus for developing the United States of Africa so far has been on building subdivisions of Africa - the proposed East African Federation can be seen as an example of this. Former President of Senegal, Abdoulaye Wade, had indicated that the United States of Africa could exist as early as 2017. The African Union, by contrast, has set itself the task of building a "united and integrated" Africa by 2025. Gaddafi had also indicated that the proposed federation may extend as far west as the Caribbean: Haiti, Jamaica, the Dominican Republic, the Bahamas and other islands featuring a large African diaspora, may be invited to join. Gaddafi also received criticism for his involvement in the movement, and lack of support for the idea from among other African leaders. A week before Gaddafi's death during the Libyan Civil War, South African President Jacob Zuma expressed relief at the regime's downfall, complaining that Gaddafi had been "intimidating" many African heads of
