How did Vasco da Gama’s voyages affect the history of Mozambique and East Africa?

Vasco da Gama’s 1498 voyage around the Cape of Good Hope initiated a transformative era of European involvement in the trade, politics, and society of the Indian Ocean world.12

Impact on East Africa

The Portuguese utilized superior military and naval technology to dominate East African city-states, forcing local rulers to pay tribute or face dethronement. By the early 16th century, they had sacked cities like Kilwa and Mombasa, eventually constructing Fort Jesus to solidify their control over regional commercial systems. This period led to the economic and cultural decline of many established coastal cities. However, Portuguese influence waned by the late 17th century, culminating in the 1698 loss of Fort Jesus to the Omanis, who subsequently reclaimed much of the Indian Ocean trade.341

Impact on Mozambique

In Mozambique, the Portuguese seized key ports like the Island of Mozambique and Sofala. They expanded into the interior along the Zambezi River, establishing garrisons and prazos (land grants) to control the gold trade. These prazos evolved into unique centers of power defended by African armies known as Chikunda, which persisted until the late 19th century.142
