One of the distinctive features of the Aztec culture was its penchant for sacrifice. Aztec myths dictated that human blood be fed to the Sun to give it the strength to rise each day. Human sacrifices were conducted on a grand scale; several thousand in a single day were not uncommon. Victims were often decapitated or flayed, and hearts were cut from living victims. Sacrifices were conducted at the top of tall pyramids to be close to the sun and blood flowed down the steps. Although the Aztec economy was based primarily on corn (or maize), the people believed that crops depended on the regular provision of sacrificial blood.



The incessant demand for sacrificial victims meant that the Aztecs tolerated loose control over satellite cities because frequent revolts offered opportunities for capturing new victims. During times of peace, "garland wars" were arranged strictly as contests of courage and warrior skill, and for the purpose of capturing victims. They fought with wooden clubs to maim and stun, rather than kill. When fighting to kill, the clubs were studded with obsidian blades.
