The Mali Federation (French: Fédération du Mali) was a country in West Africa linking the French colonies of Senegal and the Sudanese Republic (or French Sudan) for a period of only 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) which resulted in a tense stand-off and 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.
