Strait of Magellan in the context of "Last Glacial Maximum"

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.

Patagonia (Spanish pronunciation: [pataˈɣonja]) is a geographical region in southern South America that spans parts of Argentina and Chile. It includes the southern portion of the Andes mountain range, featuring lakes, fjords, temperate rainforests, and glaciers in the west, and deserts, tablelands, and steppes toward the east. The region is bounded by the Pacific Ocean to the west, the Atlantic Ocean to the east, and several waterways that connect them, including the Strait of Magellan, the Beagle Channel, and the Drake Passage to the south.

The northern limit of the region is not precisely defined; the Colorado and Barrancas rivers, which run from the Andes to the Atlantic, are commonly considered the northern limit of Argentine Patagonia; on this basis the extent of Patagonia could be defined as the provinces of Neuquén, Río Negro, Chubut and Santa Cruz, together with Patagones Partido in the far south of Buenos Aires Province. The archipelago of Tierra del Fuego is sometimes considered part of Patagonia. Most geographers and historians locate the northern limit of Chilean Patagonia at Huincul Fault, in Araucanía Region.

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.

Tierra del Fuego (/tiˈɛrə dɛl ˈfweɪɡoʊ/; Spanish: [ˈtjera ðel ˈfweɣo]; Spanish for 'Land of Fire'), also rarely called Fireland in English, is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan.

The archipelago consists of the main island, Isla Grande de Tierra del Fuego, with an area of 73,746 km (28,473 sq mi), along with numerous smaller islands, including Cape Horn and Diego Ramírez Islands. The western part of the Tierra del Fuego archipelago, about two-thirds including its many islands, is part of Chile, and the eastern part is part of Argentina. The southernmost extent of the archipelago, Cape Horn, lies just north of 56° south.

The Continental Divide of the Americas (also known as the Great Divide, the Western Divide or simply the Continental Divide; Spanish: Divisoria continental de las Américas, Gran Divisoria) is the principal, and largely mountainous, hydrological divide of the Americas. The Continental Divide extends from the Bering Strait to the Strait of Magellan, and separates the watersheds that drain into the Pacific Ocean from those river systems that drain into the Atlantic and Arctic Ocean, including those that drain into the Gulf of Mexico, the Caribbean Sea, and Hudson Bay.

Although there are many other hydrological divides in the Americas, the Continental Divide is by far the most prominent of these because it tends to follow a line of high peaks along the main ranges of the Rocky Mountains and Andes, at a generally much higher elevation than the other hydrological divisions.

The Magallanes Region (locally [maɣaˈʝanes]), officially the Magallanes y la Antártica Chilena Region (Spanish: Región de Magallanes y de la Antártica Chilena) or Magallanes and the Chilean Antarctica Region in English, is one of Chile's 16 first order administrative divisions. It is the southernmost, largest, and second least populated region of Chile. It comprises four provinces: Última Esperanza, Magallanes, Tierra del Fuego, and Antártica Chilena. The region takes its name from the Strait of Magellan which runs through it, which was in turn named after Ferdinand Magellan, the leader of the European expedition that discovered it.

Magallanes's geographical features include Torres del Paine, Cape Horn, Tierra del Fuego island, and the Strait of Magellan. It also includes the Antarctic territory claimed by Chile. Despite its large area, much of the land in the region is rugged or closed off for sheep farming, and is unsuitable for settlement. 80% of the population lives in the capital Punta Arenas, a major market city and one of the main hubs for Antarctic exploration.
