The mācēhualtin (IPA: [maːseˈwaɬtin]) were the commoner social class in the Mexica Empire.
During the reign of Moctezuma II (1502–1520), they were banned from serving in the royal palaces, as this monarch widened the divide between pipiltin (nobles) and macehualtin.
As Aztec society was in part centered around warfare —every Aztec male received basic military training from an early age—, the only possibility of upwards social mobility for mācēhualtin was through military achievement —especially the taking of captives (māltin [ˈmaːɬtin], singular malli).
