The fall of Tenochtitlan triggered massive changes in Aztec society. The power vacuum left by Moctezuma II 's death led to political chaos, with the Triple Alliance crumbling and tributary states rebelling. Spanish colonizers quickly imposed new systems of governance, like encomiendas and viceroyalties.
Aztec society faced a demographic catastrophe , with up to 90% of the population wiped out by war, disease, and famine. The economy was upended as traditional trade networks collapsed and Spanish priorities took over. Cultural destruction was widespread, with temples razed, sacred objects destroyed, and forced assimilation to European norms.
