Vasco da Gama commanded the first European expedition to reach India directly by sailing around Africa, departing Lisbon in 1497 and reaching Calicut on the Malabar Coast in May 1498.
The voyage built on decades of Portuguese Atlantic and African coastal exploration, including Bartolomeu Dias’s rounding of the southern tip of Africa in 1488. Da Gama did not discover an empty route; he entered an Indian Ocean already connected by African, Arab, Persian, Indian and Asian maritime networks.
The expedition sailed well into the South Atlantic before turning east toward the Cape, using wind patterns rather than simply following the African coast continuously.
After rounding southern Africa, da Gama’s ships reached East African ports including Mozambique, Mombasa and Malindi. Relations ranged from conflict to cooperation.
From the East African coast the expedition crossed the Indian Ocean to Calicut. The identity of the pilot who helped with this leg has been disputed; later traditions sometimes name Ahmad ibn Majid, but the connection is not securely established by contemporary evidence.
Commercial negotiations in Calicut were difficult because Portuguese trade goods did not match expectations in a sophisticated regional market.
The return voyage was severe, with scurvy and mortality among the crew. Da Gama returned to Portugal in 1499 after a journey that opened a direct Portuguese route but at great human cost.
Later Portuguese expeditions used violence and fortified trade to turn the route into an imperial system. The 1497–1499 voyage should be distinguished from those later campaigns.
