Portuguese Mozambique (Portuguese: Moçambique Portuguesa) or Portuguese East Africa (África Oriental Portuguesa) were the common terms by which Mozambique was designated during the period in which it was a Portuguese overseas province. Portuguese Mozambique originally constituted a string of Portuguese possessions along the south-east African coast, and later became a unified province, which now forms the Republic of Mozambique.
Portuguese trading settlements—and later, territories—were formed along the coast and into the Zambezi basin from 1498 when Vasco da Gama first reached the Mozambican coast. Lourenço Marques explored the area that is now Maputo Bay in 1544. The Portuguese increased efforts for occupying the interior of the colony after the Scramble for Africa, and secured political control over most of its territory in 1918, facing the resistance of some Africans during the process.
