Executive summary

The term “Aztec” refers to a dominant imperial system — chiefly the Mexica rulers of Tenochtitlán and their Triple Alliance — not a single homogeneous tribe, and Spanish conquerors used alliances and labels in practical, political ways when they described and governed Indigenous peoples (see Britannica on Aztec empire size and tributary reach) [1]. Spanish conquest relied heavily on Indigenous allies who resented Aztec domination; Spaniards then extended rule over many formerly independent polities across southern Mexico by 1525 [2] [1] [3].

1. “Aztec” as an imperial, not tribal, label

Historians treat “Aztec” as shorthand for the imperial system centered on Tenochtitlán — the Mexica-led Triple Alliance that, by 1519, controlled some 400–500 subordinate city‑states and roughly 5–6 million people across central Mexico — rather than a single tribe with uniform culture or politics [1]. Contemporary sources and later scholarship highlight that the empire’s power was built through conquest, tribute extraction and political domination over many distinct Nahua and non‑Nahua communities [1] [4].

2. Spanish use of categories: practical shorthand and political convenience

Spanish chroniclers and colonial administrators often used broad labels to describe the peoples they encountered. The conquerors encountered an imperial structure and pressed a convenient label into bureaucratic and military use; this simplified a complex patchwork of polities into a manageable category for governance, tribute, and conversion [3] [2]. Available sources do not mention a single official Spanish decree inventing “Aztec” as a blanket term, but the colonial record reveals patterns of categorization for administrative ease [3].

3. Indigenous diversity and the role of local allies in the conquest

The Spanish did not topple a monolithic people alone: they relied on tens of thousands of Indigenous warriors from polities that had been subjugated by the Mexica or resented Aztec demands for tribute and sacrificial victims, notably the Tlaxcalans [1] [5]. These alliances reveal that many local communities were politically and culturally distinct from the Mexica core and that “Aztec” rule was imperial rather than simply tribal domination [1] [5].

4. What Spanish control replaced — continuity and change

After the fall of Tenochtitlán, Spanish authorities overlaid colonial institutions on preexisting Aztec administrative structures and extended their rule through a mix of direct domination and negotiated accommodation; by 1525 Spanish rule had been extended south toward Guatemala and Honduras, though resistance — especially in the Maya regions — continued for decades [2] [3]. The transition was disruptive (destruction of records is well documented), but it also integrated many existing systems into a new colonial order [6] [2].

5. Sources disagree on emphasis; interpretive caution needed

Recent commentary emphasizes the loss of Aztec pictorial and administrative records after the conquest and warns that much of what survives is filtered through Spanish perspectives, complicating straightforward claims about identity or terminology [6]. Scientific and economic studies show that social features such as inequality predated Spanish arrival, underscoring that Aztec imperial structures had their own internal dynamics independent of European intervention [4]. Different authors therefore stress either Spanish imposition of categories, Indigenous political complexity, or the continuities within Aztec society [6] [4] [1].

6. Why the question matters today

Calling diverse subject peoples “Aztecs” flattens historical realities and can erase the autonomy of the many city‑states and ethnic groups that made up Mesoamerica. Scholars and educators now push for precision — distinguishing Mexica, Nahua, and the Triple Alliance’s tributary states — while also recognizing the practical shorthand that both contemporaries and later writers used [1] [6]. This matters for historical accountability, cultural recognition, and how modern identities are framed.

Limitations and gaps: available sources do not mention a single Spanish official coinage of “Aztec” as a deliberate generalizing slur; scholarship shows a more complex process of labeling, alliance-making and administrative practice documented across the cited sources [3] [1] [6].
