Final answer:
The city-states in Central Mexico went to war primarily due to competition for resources and power. Religious differences, cultural exchange, and mutual cooperation for defense might have influenced specific instances of war.
Step-by-step explanation:
The city-states in Central Mexico went to war against one another primarily due to competition for resources and power. Each city-state sought to expand its territory and gain control over valuable resources such as land, water, and agricultural surplus. This drove them to engage in conflicts and conquests with their neighboring city-states.
Additionally, alliances and rivalries were formed based on political and economic interests. Some city-states formed alliances to strengthen their power and defend against external threats, while others competed against each other in order to establish dominance in the region.
Religious differences, cultural exchange, and mutual cooperation for defense might have influenced specific instances of war, but overall, competition for resources and power played a central role in the conflict between city-states in Central Mexico.
