Portuguese trade expands along the Sena–Tete–Zambezi corridor

From the 1530s, Portuguese merchants increasingly operated along the lower Zambezi through Sena, Tete and connected river settlements. The corridor carried goods and information between the coast, the gold-producing regions associated with Mutapa and the trading centres of the Indian Ocean. Portuguese traders entered routes already used by African and Muslim merchants, relying on local carriers, brokers, rulers and river transport.

Sena and Tete were useful because they connected river movement with overland routes into the interior. The surviving evidence does not support a single moment when Portuguese control began: trade, settlement, military protection and administrative claims developed unevenly. The corridor later became important to the Barreto expedition and to Portuguese attempts to establish forts and regulate access to gold and silver-bearing regions.

Significance

The corridor linked coastal Portuguese activity to Mutapa diplomacy, river transport and inland trade, creating the geographic basis for later Portuguese military and administrative projects.
