The Union of African States: Ghana, Guinea, and Mali's Attempt at Federation

Before the Organisation of African Unity offered a looser, sovereignty-respecting model of continental cooperation, three West African leaders tried something far more ambitious: an actual political federation. The Union of African States, linking Ghana, Guinea, and Mali, was the most concrete attempt in the independence era to build a single African state out of formerly separate colonial territories, and its quiet collapse within a few years illustrated exactly why that ambition proved so hard to realize.

The project began smaller and earlier than it is often remembered. In November 1958, Kwame Nkrumah of Ghana and Ahmed Sékou Touré of Guinea met in Conakry, where Ghana offered emergency financial support to Guinea, which had just become independent from France that October after alone voting to reject Charles de Gaulle’s French Community, and faced a punishing economic rupture with Paris as a result. That cooperation was formalized on May 1, 1959, as the Union of Independent African States, joining two countries that had been colonized by different European powers, Britain and France respectively, itself a symbolically significant first for the continent.

Mali’s president, Modibo Keïta, joined the arrangement afterward. Keïta led the Sudanese Republic, which became the independent Republic of Mali in September 1960 following the brief collapse of the Mali Federation with Senegal; he was Mali’s head of state, not Guinea’s, a distinction sometimes blurred in popular accounts since all three men were closely allied. Nkrumah, Touré, and Keïta met in Conakry in December 1960 and agreed in principle to bring Mali into the union. The three signed a formal charter establishing the renamed Union of African States at a meeting in Accra in the spring of 1961, and that charter was published simultaneously in Accra, Conakry, and Bamako on July 1, 1961.

On paper, the union’s ambitions were substantial: a shared currency backed by a joint union bank and economic council, shared citizenship among the three countries’ populations, and coordinated foreign, economic, educational, and cultural policy. Nkrumah, the union’s most vocal champion, described it as intended to serve as the nucleus of a future United States of Africa. In practice, none of that institutional machinery was ever built. The union never established a joint parliament, currency, or standing administration, and it functioned largely as a political alliance between three sympathetic heads of state rather than a functioning federal government.

It did not last. Broader continental politics pulled the three governments apart: Touré grew wary of Nkrumah’s increasingly assertive push for continental political union in the run-up to the 1963 founding of the OAU, and strains widened further after a 1963 coup in neighboring Togo that Nkrumah was suspected of having supported. By May 1963, the Union of African States had dissolved without any formal declaration ending it. No other African state ever joined, and the three founding members redirected their energy into the OAU’s more modest framework of cooperation among fully sovereign states, a model that ultimately prevailed over Nkrumah’s federalist vision.
