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 colony. Portuguese Mozambique originally constituted a string of Portuguese possessions along the south-east African coast, and later became a unified colony, which now forms the Republic of Mozambique.
Portuguese trading settlements—and later, colonies—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 Africans during the process.
Some territories in Mozambique were handed over in the late 19th century for rule by chartered companies like the Mozambique Company (Companhia de Moçambique), which had the concession of the lands corresponding to the present-day provinces of Manica and Sofala, and the Niassa Company (Companhia do Niassa), which had controlled the lands of the modern provinces of Cabo Delgado and Niassa. The Mozambique Company relinquished its territories back to Portuguese control in 1942, unifying Mozambique under control of the Portuguese government.
The region as a whole was long officially termed Portuguese East Africa, and was subdivided into a series of colonies extending from Lourenço Marques in the south to Niassa in the north. Cabo Delgado was initially merely a strip of territory along the Rovuma River, including Cape Delgado itself, which Portugal acquired out of German East Africa in 1919, but it was enlarged southward to the Lurio River to form what is now Cabo Delgado Province. In the Zambezi basin were the colonies of Quelimane (now Zambezia Province) and Tete (in the panhandle between Northern Rhodesia, now Zambia, and Southern Rhodesia, now Zimbabwe), which were for a time merged as Zambezia. The colony of Moçambique (now Nampula Province) had the Island of Mozambique as its capital. The island was also the seat of the Governor-General of Portuguese East Africa until the late 1890s, when that official was officially moved to the city of Lourenço Marques. Also in the south was the colony of Inhambane, which lay north-east of Lourenço Marques. Once these colonies were merged, the region as a whole became known as Moçambique.
According to the official policy of the Salazar regime, inspired on the concept of Lusotropicalismo, Mozambique was claimed as an integral part of the "pluricontinental and multiracial nation" of Portugal, as was done in all of its colonies to Europeanise the local population and assimilate them into Portuguese culture. This policy was largely unsuccessful, however, and African opposition to colonisation led to a ten-year independence war that culminated in the Carnation Revolution at Lisbon in April 1974 and the independence from Portugal in June 1975.
During its history as a Portuguese colony, the present-day territory of Mozambique had the following formal designations:
Until the 20th century, the land and peoples of Mozambique were barely affected by the Europeans who came to its shores and entered its major rivers. As the Muslim traders, mostly Swahili, were displaced from their coastal centres and routes to the interior by the Portuguese, migrations of Bantu peoples continued and tribal federations formed and reformed as the relative power of local chiefs changed. For four centuries the Portuguese presence was meagre. Coastal and river trading posts were built, abandoned, and built again. Governors sought personal profits to take back to Portugal, and colonists were not attracted to the distant area with its relatively unattractive climate; those who stayed were traders who married local women and successfully maintained relations with local chiefs.
In Portugal, however, Mozambique was considered to be a vital part of a world empire. Periodic recognition of the relative insignificance of the revenues it could produce was tempered by the mystique which developed regarding the mission of the Portuguese to bring their civilisation to the African territory. It was believed that through missionary activity and other direct contact between Africans and Europeans, the Africans could be taught to appreciate and participate in Portuguese culture.
In the last decade of the 19th century and the first part of the 20th century, integration of Mozambique into the structure of the Portuguese nation was begun. After all of the area of the present province had been recognised by other European powers as belonging to Portugal, administrators waged wars against African polities to assert control over the territory. Civil administration was established throughout the area, the building of an infrastructure was begun, and agreements regarding the transit trade of Mozambique's land-locked neighbours to the west, such as Southern Rhodesia, Northern Rhodesia and Nyasaland, were made.
Colonial legislation discriminated against Africans on cultural grounds. Colonial legislation submitted Africans to forced labour, to pass laws and to segregation in schools. That most Africans were perceived to engage in "uncivilised behaviour" by the Portuguese created a low opinion of Africans as a group among Europeans. The uneducated Portuguese immigrant peasants in urban areas were frequently in direct competition with Africans for jobs and demonstrated jealousies and racial prejudice.
Between the urban and rural sectors of the society lied a steadily increasing group of Africans who were loosening their ties with rural villages and starting to participate in the urban economy, to settle in suburbs, and to adopt European customs. Members of this group would later become active participants in the independence movement.
When Portuguese explorers reached East Africa in 1498, Swahili commercial settlements had existed along the Swahili Coast and outlying islands for several centuries. From about 1500, Portuguese trading posts and forts became regular ports of call on the new route to the east.
The voyage of Vasco da Gama around the Cape of Good Hope into the Indian Ocean in 1498 marked the Portuguese entry into trade, politics, and society in the Indian Ocean world. The Portuguese gained control of the Island of Mozambique and the port city of Sofala in the early 16th century. Vasco da Gama having visited Mombasa in 1498 was then successful in reaching India thereby permitting the Portuguese to trade with the Far East directly by sea, thus challenging older trading networks of mixed land and sea routes, such as the spice trade routes that used the Persian Gulf, Red Sea and caravans to reach the eastern Mediterranea
