Setting the scene
By the 1490s, Portugal had spent decades exploring the African coast, seeking a sea route to India to bypass Ottoman-controlled overland spice routes. Bartolomeu Dias rounded the Cape of Good Hope in 1488 but turned back. King Manuel I commissioned Vasco da Gama, a nobleman with naval experience, to complete the voyage. On July 8, 1497, da Gama departed Lisbon with four ships and 170 men, following Dias's route south, then swinging west into the Atlantic to catch favorable winds—a technique called the volta do mar.
What happened
After rounding the Cape in November 1497, da Gama sailed up Africa's east coast, stopping at Mozambique, Mombasa (where he was hostilely received), and Malindi, where he hired an Arab pilot, possibly Ibn Majid, who guided him across the Indian Ocean using monsoon winds. On May 20, 1498, da Gama reached Calicut (Kozhikode) on India's Malabar Coast, the center of the pepper trade. The Zamorin (ruler) of Calicut received him coolly—da Gama's trade goods were inferior, and Muslim merchants, who dominated the trade, opposed him. He left in August with a small cargo of spices.
Why it still matters
Da Gama returned to Lisbon in September 1499, having lost two ships and half his crew to scurvy, but his cargo sold for 60 times the voyage's cost. He had established the first direct sea route from Europe to Asia, bypassing the Mediterranean and breaking Venice's spice monopoly. Da Gama made two more voyages, the second in 1502 involving brutal violence against Arab shipping, and became Viceroy of India in 1524, dying there that year. His voyage inaugurated the Portuguese Empire in Asia and the age of European colonialism in the Indian Ocean, with devastating consequences for existing trade networks.【2013085313067715703†L5-L7】
Background
European trade with Asia shifted toward oceanic paths. Even centuries later, this episode remains a reference point for how empires rise, fracture, and transform.
