Why did the aztects abandoned their cities?

The Aztecs abandoned their cities primarily due to a combination of factors, including severe drought, resource depletion, and internal strife. These environmental challenges led to food shortages and weakened their agricultural systems. Additionally, the arrival of Spanish conquistadors and subsequent military confrontations further destabilized their society, prompting many to flee or abandon urban centers. The culmination of these pressures ultimately led to the decline of the Aztec civilization.
