The Aztec were a pre-Columbian middle American civilization, whose realm was mostly confined to what today is central Mexico and Yucatan. They were conquered by the Spanish during the early 16th century.
The Aztec were a highly evolved culture of warriors and farmers. Human sacrifice was common, as in many meso-American cultures like the Maya.
