What were the consequences of spain’s conquest of the aztec and the incas?

The effect the Spanish had on the Aztec Empire a mixed lot. Historians often disagree on the impact, both positive and negative, that the Spanish had on Aztec civilization. Under the leadership of Hernan Cortes in 1521, the Aztec Empire was destroyed. The Aztec were a primitive people who practice rituals that were inhumane. Spanish rule put an end to those cruel tradition. Hope this helped.
