The Aztecs were also known as the Tenochca (from which the name for their capital city, Tenochtitlan, was derived) or the Mexica (the origin of the name of the city that would replace Tenochtitlan, as well as the name for the entire country).
The tribe of nomads that settled the city of TenochtitlÃ¡n were the Mexica (pronounced me-SHEE-ka), who had migrated from the north, from their legendary origins of AztlÃ¡n. As early as the Spanish conquest, Mexico City took on the name Ciudad de MÃ©xico.
