Juan Sebastián Elcano in the context of "Spherical Earth"

Ferdinand Magellan (c. 1480 – 27 April 1521) was a Portuguese explorer best known for planning and leading the 1519–22 Spanish expedition to the East Indies. During this expedition, he discovered the Strait of Magellan, performed the first European crossing of the Pacific Ocean, and made the first known European contact with the Philippines. Magellan himself was killed in battle in the Philippines in 1521, but his crew, commanded by Spanish navigator Juan Sebastián Elcano, completed the return trip to Spain in 1522, achieving the first circumnavigation of Earth in history.

Born around 1480 into a family of minor Portuguese nobility, Magellan became a skilled sailor and naval officer in the service of the Portuguese Crown in Asia. However, King Manuel I refused to support Magellan's plan to reach the Moluccas, or Spice Islands, by sailing westwards around the American continent. Magellan then proposed the same plan to King Charles I of Spain, who approved it. In Seville, he married, fathered two children, and organized the expedition. In 1518, for his allegiance to the Hispanic monarchy, Magellan was appointed an admiral of the Spanish fleet and given command of the expedition—the five-ship "Armada of Molucca." He also was made a Commander of the Order of Santiago, one of the highest military ranks of the Spanish Empire.

The Magellan expedition (10 August or 20 September 1519 – 6 September 1522) was the first voyage around the world in human history. It was a Spanish expedition that sailed from Seville in 1519 under the initial command of Ferdinand Magellan, a Portuguese sailor, and completed in 1522 by Spanish Basque navigator Juan Sebastián Elcano.

The initial goal of the voyage was to secure time to explore the possibility of a southwestern passage around South America to China and the Spice Islands (now part of Indonesia). After crossing the Atlantic, wintering in Patagonia, and suppressing a mutiny, the expedition found and transited the Straits of Magellan in 1520. After crossing the Pacific Ocean to the Philippines, Magellan was killed during a raid on the Mactan chief Lapulapu in 1521. The ship Victoria under Juan Sebastian Elcano—who began the expedition as a boatswain— took command of the expedition and sailed into the open Indian Ocean, avoided landing in South Africa despite the resulting starvation, and bluffed his way into resupply at the Cape Verde Islands before completing the first circumnavigation on 6 September 1522. Of the initial 270 crew members, only 18 sailors completed the entire journey.

The Magellan expedition, sometimes termed the Magellan–Elcano expedition, was a 16th-century Spanish expedition planned and led by Portuguese explorer Ferdinand Magellan. Its purpose was to secure a maritime trade route with the Moluccas, or Spice Islands, in present-day Indonesia. The expedition departed Spain in 1519 and returned there in 1522 under the command of Spanish navigator Juan Sebastián Elcano, who completed the voyage after Magellan's death in the Philippines. One of the most significant voyages in the Age of Discovery, the nearly three-year expedition totaled 60,440 km (37,560 mi) and achieved the first circumnavigation of Earth in history. It also marked the first crossing of the Pacific by a European expedition, revealing the vast scale of that ocean, and proved that ships could sail around the world on a western sea route.

The five-ship fleet left Spain on 20 September 1519 with about 270 men. After crossing the Atlantic Ocean, the ships continued south along the eastern coast of South America. Entering the Strait of Magellan on 1 November 1520, the fleet passed through to the Pacific Ocean, which Magellan himself named Mar Pacifico. The fleet crossed the Pacific in 98 days, stopped in Guam and the Philippines, and successfully reached the Moluccas in November 1521. A much-depleted crew led by Elcano finally returned to Spain on 6 September 1522, having sailed west across the Indian Ocean, around the Cape of Good Hope through waters controlled by the Portuguese, and north along the west African coast to finally arrive in Spain.

Antonio Pigafetta (Italian: [anˈtɔːnjo piɡaˈfetta]; c. 1491 – c. 1531) was a Venetian scholar and explorer. In 1519, he joined the Spanish expedition to the Spice Islands led by Portuguese explorer Ferdinand Magellan, the world's first circumnavigation, and is best known for being the chronicler of the voyage. During the expedition, he served as Magellan's assistant until Magellan's death in the Philippine Islands, and kept an accurate journal, which later assisted him in translating the Cebuano language. It is the first recorded document concerning the language.

Pigafetta was one of the 18 men who made the complete trip, returning to Spain in 1522, under the command of Juan Sebastián Elcano, out of the approximately 240 who set out three years earlier. These men completed the first circumnavigation of the world while others mutinied and returned in the first year. Pigafetta's surviving journal is the source for much of what is known about Magellan and Elcano's voyage.
