What happened
Moctezuma II succeeded his uncle Ahuitzotl as huey tlatoani in 1502, inheriting an empire at what World History Encyclopedia's chronology records as its greatest territorial extent, extracting tribute from 371 city-states across 38 provinces covering roughly 200,000 square kilometers. Unlike Ahuitzotl's aggressive expansion, Moctezuma II's reign focused on consolidating and administering the territory his predecessors had conquered rather than adding significantly to it, while also working to centralize religious and political authority more tightly around Tenochtitlan and his own person. He continued to fight Flower Wars against Tlaxcala and neighboring holdouts, keeping long-standing tensions with those unconquered city-states alive right up to the point when Hernan Cortes would arrive looking for allies willing to fight against Tenochtitlan.
Why it matters
Moctezuma II inherited the largest, wealthiest version of the empire that would ever exist, but also inherited its accumulated enemies. The unconquered city-states his predecessors had spent decades fighting and provoking, Tlaxcala most of all, would prove decisive when a small Spanish force arrived seeking exactly the local allies that decades of Aztec expansion had been creating.
How we know
The empire's territorial and demographic scale at this date is described in the Codex Mendoza, a mid-16th-century Spanish-commissioned document based on earlier Aztec tribute records, cross-referenced with modern archaeological and historical synthesis.
