The Mali Federation () was a federation in West Africa linking the French colonies of Senegal and the Sudanese Republic (or French Sudan) for two months in 1960. It was founded on 4 April 1959 as a territory with self-rule within the French Community and became independent after negotiations with France on 20 June 1960. Two months later, on 19 August 1960, the Sudanese Republic leaders in the Mali Federation mobilized the army, and Senegal leaders in the federation retaliated by mobilizing the gendarmerie (national police); this resulted in a tense stand-off, and led to the withdrawal from the federation by Senegal the next day. The Sudanese Republic officials resisted this dissolution, cut off diplomatic relations with Senegal, and defiantly changed the name of their country to Mali. For the brief existence of the Mali Federation, the premier was Modibo Keïta, who would later become the first President of Mali, and its government was based in Dakar, the eventual capital of Senegal. Background After World War II, the colonies of French West Africa began pushing significantly for increased self-determination and to redefine their colonial relationships with France. Following the May 1958 crisis, the colonies of French West Africa were given the chance to vote for immediate independence or to join a reorganized French Community (an arrangement which would grant the colonies some self-determination while maintaining ties to France). Only Guinea voted for full independence and the other colonies of French West Africa voted to join the French Community. In the 1958 election to decide the issue of independence, two major parties split the countries of west Africa: the African Democratic Rally (, commonly known as the RDA) and the African Regroupment Party (, commonly known as the PRA). The two regional groupings of parties struggled against one another on the issue of independence and the extent of ties with France. The RDA was the governing party in the Ivory Coast colony, the French Sudan colony, and Guinea while the PRA was a major governing party in Senegal and had sizable majorities in many countries. The two parties also were part of coalition governments in French Upper Volta, Niger, and French Dahomey. Both two parties struggled with each other to shape the political future of the region, Mauritania often became a neutral party that would break any deadlocks. The vote of 1958 revealed a number of divisions within the parties. The
