Mexico prior to the Spanish conquest, or specifically the Mexica ethnicity of the Nahuatl-speaking tribes (from ). The name comes from the singular Nahuatl word () that means "[people] from Aztlan", reflecting the mythical place of origin for Nahua peoples. History Before the Aztec Empire Nahua peoples descended from Chichimec peoples, who migrated to central Mexico from the north (mainly centered sparsely around present-day states of Zacatecas, San Luis Potosí, and Guanajuato) in the early 13th century. The migration story of the Mexica is similar to those of other polities in central Mexico, with supernatural sites, individuals, and events, joining earthly and divine history, as they sought political legitimacy. Pictographic codices in which the Aztecs recorded their history say that the empire's place of origin was called Aztlán. Early migrants settled the Basin of Mexico and surrounding lands by establishing a series of independent city-states. These early Nahua city-states or were ruled by dynastic heads called (singularly ). Most of the existing settlements had been established by other indigenous peoples before the Mexica migration. These early city-states fought various small-scale wars with each other but no individual city gained dominance due to shifting alliances. The Mexica were the last of the Nahua migrants to arrive in Central Mexico. They entered the Basin of Mexico around the year 1250, and, by then, most of the good agricultural land had already been claimed. The Mexica persuaded the king of Culhuacan, a small city-state but important historically as a refuge of the Toltecs to make them settle in a relatively infertile patch of land called Chapultepec (Chapoltepēc, "in the hill of grasshoppers"). The Mexica served as mercenaries for Culhuacan. After the Mexica served Culhuacan in battle, the ruler appointed one of his daughters to rule over the Mexica. Mythological native accounts say that the Mexica instead sacrificed her by flaying her skin on the command of their god Xipe Totec. The ruler of Culhuacan attacked and used his army to drive the Mexica from Tizaapan by force when he learned of this. The Mexica moved to an island in the middle of Lake Texcoco where an eagle nested on a nopal cactus. The Mexica interpreted this as a sign from their gods and founded their new city Tenochtitlan on this island in the year (or "Two House", 1325 AD).
