Answer:
One technique implemented by the Aztec Empire to generate revenue and consolidate power was through tributes from the conquered regions. Tributes were regularly collected as a collaborative effort by the members of an alliance. Tributes usually consisted of items such as warrior costumes, shields, tropical feathers, copal incense, paper, food, and animal products. Official tribute collectors, also known as calpixque, were located in the conquered provinces to oversee the payments and make sure that the tributes were paid. Regions that failed to pay the tributes were severely punished.
Another technique the Aztecs utilized to generate revenue and consolidate power was taxation over their citizens. With the exception of priests, nobles, minors, orphans, invalids, and beggars, the empire required a payment to be made to them from everyone else. Merchants paid taxes on the goods that they sold, artisans paid taxes based on the value of their products, and barrios paid taxes through their crop production. Failure to pay these taxes resulted in slavery or property confiscation.
