Why did the Aztecs go to war often?

The Aztecs went to war often primarily to acquire resources, particularly for tribute and military conquest, which were essential for their expanding empire. They sought to capture prisoners for religious sacrifices, which were integral to their belief system and societal stability. Additionally, warfare allowed them to assert dominance over rival city-states and secure political alliances. This cycle of conflict was deeply rooted in their culture and economy, driving their relentless pursuit of power and expansion.
