Mexica

The Mexica are a Nahuatl-speaking people of the Valley of Mexico who were the rulers of the Triple Alliance, more commonly referred to as the Aztec Empire. The Mexica established Tenochtitlan, a settlement on an island in Lake Texcoco, in 1325. A dissident group in Tenochtitlan separated and founded the settlement of Tlatelolco with its own dynastic lineage. In 1521, their empire was overthrown by an alliance of Spanish conquistadors and rival indigenous nations, most prominently the Tlaxcaltecs.
