The General Captaincy of Chile, Governorate of Chile, or Kingdom of Chile, was a territory of the Spanish Empire from 1541 to 1818 that was, initially, part of the Viceroyalty of Peru. It comprised most of modern-day Chile and southern parts of Argentina in the Patagonia region. Its capital was Santiago de Chile. In 1810 it declared itself independent, with the Spanish reconquering the territory in 1814, but in 1818 it gained independence as the Republic of Chile. It had a number of Spanish governors over its long history and several kings.

The Strait of Magellan, also called the Straits of Magellan, is a navigable sea route in southern Chile separating mainland South America to the north and Tierra del Fuego to the south. The strait is considered the most important natural passage between the Atlantic and Pacific oceans. The strait is approximately 570 km long and 2 km wide at its narrowest point. In 1520, the Spanish expedition of the Portuguese navigator Ferdinand Magellan, after whom the strait is named, became the first Europeans to discover it.
