Maputo was founded in the late 18th century in a region visited (1544) by the Portuguese trader Lourenço Marques for whom it was named until the present name was adopted in 1976. It replaced Moçambique as the colonial capital of Portuguese East Africa in 1907 and continued as capital when the country achieved independence in 1975. Population (1991 estimate) 1,098,000.
