Question

What tactic did the aztecs use to strengthen their empire?

Answer 1

Thank you for posting your question here at Brainly.com But on to the question

The answer would be They had a strict governor rule over the conquered lands.

They did this because of the many people that would protest or even maybe fight back so they had to keep an close eye on them for quite some time

hoped this helped. ^-^

Answer 2

They sacrificed the enemy tribes to the gods and they had a sophistic communication line of worriers running hundreds of miles to reach the empire.
