Modibo Keïta
Senegal withdrew from the federation in August 1960, which allowed the Sudanese Republic to become the independent Republic of Mali on 22 September 1960, and that date is now the country's Independence Day. Modibo Keïta was elected the first president. Keïta quickly established a one-party state, adopted an independent African and socialist orientation with close ties to the East, and implemented extensive nationalization of economic resources. In 1960, the population of Mali was reported to be about 4.1 million.
