The Mexica (Aztecs) founded Tenochtitlan in 1325 on an island in Lake Texcoco, in the Valley of Mexico.
Guided by their patron god Huitzilopochtli, they built a magnificent city that became the capital of the Aztec Empire. After the Spanish conquest (1519–1521), Tenochtitlan was razed and rebuilt as Mexico City, the capital of New Spain and later modern Mexico.
