The Aztecs were a Nahuatl-speaking civilisation inhabiting central and southern parts of what nowadays is Mexico. Their civilisation reached its prime in the 14-16th centuries before the arrival of the Spanish conquistadors that incorporated once vibrant society into the Spanish Empire.
The Aztecs are famous for their outstanding system of agriculture and irrigation that contributed to their development and might.
They are also notorious for their shocking and gory rituals that include human sacrifice - including heart-extraction.
