Answer:
The Portuguese nobleman Vasco da Gama (1460-1524) sailed from Lisbon in 1497 on a mission to reach India and open a sea route from Europe to the East. After sailing down the western coast of Africa and rounding the Cape of Good Hope, his expedition made numerous stops in Africa before reaching the trading post of Calicut, India, in May 1498. Da Gama received a hero’s welcome back in Portugal, and was sent on a second expedition to India in 1502, during which he brutally clashed with Muslim traders in the region. Two decades later, da Gama again returned to India, this time as Portuguese viceroy; he died there of an illness in late 1524.
Vasco da Gama’s Early Life and First Voyage to India
Born circa 1460, Vasco da Gama was the son of a minor nobleman who commanded the fortress at Sines, located on the coast of the Alentejo province in southwestern Portugal. Little else is known about his early life, but in 1492 King John II sent da Gama to the port city of Setubal (south of Lisbon) and to the Algarve region to seize French ships in retaliation for French attacks on Portuguese shipping interests.

Did you know? By the time Vasco da Gama returned from his first voyage to India in 1499, he had spent more than two years away from home, including 300 days at sea, and had traveled some 24,000 miles. Only 54 of his original crew of 170 men returned with him; the majority (including da Gama's brother Paolo) had died of illnesses such as scurvy.</u></h2>
