History
The people of the Aztec empire, called the Nahua, originally came from north Mexico. The main tribe, called the Mexica (pronounced "Meh-shee-kah") founded the future capital city of the Aztecs, Tenochtitlan, at around 1325 AD.

After that, they became vassals of the Azcapotzalco, A regional power, for the next 50 years. After which, they allied with two other city-states, Texcoco and Tlacopan, to defeat the Azcapotzalco in 1428. This alliance was called the "Aztec Triple Alliance". Tenochtitlan eventually became dominant over the other two. Over the next 100 years, they would go on to conquer the valley of Mexico.
