Tlatelolco (Classical Nahuatl: Mēxihco-Tlatelōlco [tɬateˈloːɬko], modern Nahuatl pronunciation^ⓘ) (also called Mexico Tlatelolco) was a pre-Columbian altepetl, or city-state, in the Valley of Mexico. Its inhabitants, known as the Tlatelolca, were part of the Mexica, a Nahuatl-speaking people who arrived in what is now central Mexico in the 13th century. The Mexica settled on an island in Lake Texcoco and founded the altepetl of Mexico-Tenochtitlan on the southern portion of the island. In 1337, a group of dissident Mexica broke away from the Tenochca leadership in Tenochtitlan and founded Mexico-Tlatelolco on the northern portion of the island. Tenochtitlan was closely tied with its sister city, which was largely dependent on the market of Tlatelolco, the most important site of commerce in the area.^[1]
