Mali Federation
The Mali Federation was a federation in West Africa that linked the French colonies of Senegal and the Sudanese Republic 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 after independence, on 19 August 1960, Sudanese Republic leaders in the federation tried to take control by mobilizing the army, and Senegalese leaders in the federation retaliated by mobilizing the gendarmerie (national police); this resulted in a tense standoff, and Senegal withdrew from the federation the next day.
