Did Magellan sail around the world?
No. Ferdinand Magellan died partway through the voyage and never completed the circumnavigation his expedition is named for.
What happened. Magellan, a Portuguese navigator sailing for the Spanish crown, departed in 1519 with five ships and around 270 men, seeking a westward route to the Spice Islands. The expedition crossed the Atlantic, endured mutiny and the loss of ships, and eventually found the passage at the southern tip of South America now called the Strait of Magellan — a genuine achievement, navigated without charts through a maze of channels.
They crossed the Pacific, which proved vastly larger than anticipated. The crossing took over three months with severe starvation and scurvy.
Magellan was killed in April 1521 in the Philippines, at the Battle of Mactan, fighting local forces led by Lapulapu after intervening in a local dispute. He had covered roughly half the distance.
Who actually completed it. Juan Sebastián Elcano, a Basque navigator and one of the mutineers Magellan had earlier pardoned, took command of the surviving ship Victoria and brought it back to Spain in September 1522 — three years after departure, with 18 of the original crew aboard. A further group returned later after imprisonment.
Elcano, not Magellan, was the first captain to complete a circumnavigation, and he was honoured accordingly in Spain at the time.
A stronger claim exists for someone else entirely. Enrique of Malacca, Magellan's enslaved interpreter, had originally been taken from Southeast Asia to Europe. If he reached his homeland during the voyage — which is plausible but not firmly established — he would have been the first person to circle the globe, having completed the journey in two stages.
Lapulapu is a national hero in the Philippines, commemorated for resisting the expedition.
