Aztecs were cannibals. Hernan Cortez wrote extensively in his journals about them. They essentially ran Mexico but their king had prophesized of Cortez arriving down to the day and how he would appear, he kept it secret mostly but relinquished control to Cortez.

The other Aztecs revolted and the war began, they were shitty warriors compared to the Spaniards, small and weaker. The Spaniards with a few thousand killed hundreds of thousands. The journals are almost comical.

Back to the Aztecs, they had theaters in Mexico city were you could watch torture, rooms made of baby bones, were you could watch babies of other tribes tortured. They were awful

If you ever wonder why the cartels are so nasty and violent, realize those are the same people.

Cortez should have wiped them out completely but he was a devout Christian and refused to attack anyone who converted to Christianity and that is why Aztec descendants remain today.

As for the other tribes, most of them converted fast. Cuba for example, the men simply surrendered themselves as slaves, their attractive women became Spanish wives and the old/ugly became servants. Same for Cozumel, Puerto Rico and the other islands.

Very fascinating stuff
