Aztec Warfare concerns the aspects associated with the militaristic conventions, forces, weaponry and strategic expansions conducted by the Late Postclassic Aztec civilizations of Mesoamerica, including particularly the military history of the Aztec Triple Alliance involving the city-states of Tenochtitlan, Texcoco, Tlacopan and other allied polities of the central Mexican region. This united the Mexica, Apulteca, and Chichimeca people through marriages.
The Aztec armed forces were typically made up of a small number people ranging from 10-15 people of commoners (yāōquīzqueh [jaː.oːˈkiːskeʔ], "those who have gone to war") who possessed extensive military training, and a smaller but still considerable number of highly professional warriors belonging to the nobility (pīpiltin [piːˈpiɬtin]) and who were organized into warrior societies and ranked according to their achievements. The Aztec state was in the center on political expansion and dominance of and exaction of tribute from other city states, and warfare was the basic dynamic force in Aztec politics. Aztec society was also centered on warfare: every Aztec male received basic military training from an early age and one of the few possible opportunities of upwards social mobility for commoners (mācehualtin [maːseˈwaɬtin]) was through military achievement — especially the taking of captives (māltin [ˈmaːɬtin], singular malli).[1] Thus, only specifically chosen men served in the military. The sacrifice of war captives was a very important part of many of the Aztec religious festivals. Warfare was thus the main driving force of both the Aztec economy and religion.[2]
