African Union State.

The Union of African States, was a short lasting union of 3 African states in West Africa, in the 1960's. These states were Mali, Ghana, and Guinea. They united together to form the Union of African States. This union was Marxist politically, and was lead by such African revolutionaries as Kwame Nkrumah of Ghana and Sékou Touré of Guinea, who was president of Guinea.
On 23 November 1958 a Ghana-Guinea Union was formed with a flag like that of Ghana but with two black stars. In May 1959 it was announced that the Union would be renamed Union of African States with a flag like that of Ghana "with as many black stars as there were members".[citation needed] In April 1961 Mali joined this union, so the flag then had three stars. The Union fell apart in 1962, when Guinea started to reach out to the United States, against the acquaintance of their Socialist partner, the U.S.S.R..
This was the inspiration for the famous song "Ghana, Guinea, Mali union" by grandfather of Highlife E.T. Mensah
