Paying tribute included giving gold or human sacrifice victims to a larger, more powerful empire. which empire forced others to pay tribute? aztec empire inca empire spanish empire portuguese empire

The correct answer is " Aztec Empire."

One of the main sources of income for the Aztec Empire was tribute. The conquered regions paid tribute to the emperor.

Tribute was collected every 80 days, 6 months, or 12 months depending on the goods being collected and the distance that had to be traveled.  

Tribute items included warrior costumes and shields, tropical feathers, incense, paper, food, and animal products. They were always reasonable and only increased if region reneged on its obligations. If a region failed to pay tribute it would be severely punished.

Official tribute collectors, lived in each of the conquered provinces and ensured that payments were made as required
