They Built One Of The Largest And Most Powerful Empires In Mesoamerica

The Mexica were a group of migrants that came in the Mexican Valley around 1250 AD and constructed Tenochtitlan in 1325 AD. They first joined with and paid tribute to Azcapotzalco, the Tepanec Empire's capital city. The Azcapotzalco king orchestrated the death of the Mexica monarch in 1426. Tenochtitlan joined forces with the city-states of Texcoco, Tlacopan, and Huexotzinco to fight Azcapotzalco the following year. In 1428, they were triumphant. Huexotzinco withdrew after the war. The Triple Alliance was created by the other three city-states, with Tenochtitlan emerging as the main force. Following its creation, the coalition launched conquest wars and rapidly expanded.

At its peak, the Triple Alliance, sometimes known as the Aztec Empire, ruled over most of central Mexico as well as surrounding lands. It was 80,000 square miles in size, with 25 million people living in nearly 500 towns and cities. Prior to the Spanish conquest, it was one of the largest and most powerful empires in Mesoamerica, the region of Mexico and Central America. The word Aztec is frequently used to refer solely to the Mexica people of Tenochtitlan, but it is also applied to the Acolhuas of Texcoco and the Tepanecs of Tlacopan.
