Traditionally, historians believed that taking captives was a major goal in Mexica warfare, and this tendency has even been given as a reason why the Spanish conquistadors defeated the Mexica. Although historians have largely revised these conclusions, the perception that captives were important to Aztec strategy and warfare persists. In this article I argue that the need for captives was not great enough to affect Aztec military strategy or battlefield conduct. First, rituals only needed a small number of victims, which could easily be acquired through the normal course of battle, and thus did not constitute a specific objective. Second, Mexica strategy focused on economic objectives, rather than captive taking. Finally, individual warriors were not well equipped to take prisoners. Although captives played a vital role in Mexica society, the practice should be thought of as opportunistic, rather than strategic.
