It is Angola's primary port, and its major industrial, cultural and urban centre. Located on Angola's northern Atlantic coast, Luanda is Angola's administrative centre, its chief seaport, and also the capital of the Luanda Province. Luanda and its metropolitan area is the most populous Portuguese-speaking capital city in the world and the most populous Lusophone city outside Brazil. In 2020 the population reached more than 8.3 million inhabitants (a third of Angola's population). Among the oldest colonial cities of Africa, Luanda was founded in January 1576 as São Paulo da Assunção de Loanda by Portuguese explorer Paulo Dias de Novais, being occasionally called "Leonda" or "St Paul de Leonda" by non-portuguese sources. The city served as the centre of the slave trade to Brazil before the institution was prohibited.
