Beginning in the late 1300s, the Aztecs were a group of American Indian peoples who lived in what today is Mexico. Most of the Aztecs were commoners, who provided the labor needed for the culture to thrive. They built impressive pyramid-type structures and cities, such as Tenochtitlan. The culture collapsed when Spanish conquistadors overtook the Aztecs in the 1500s.
