How many times do I have to tell them that I am NOT interested in giving my beating heart for their silly sacrifice rituals???
That was the Aztecs. Though I suppose the Maya might have done it as well. (Shows what I know about "indigenous pipples, huh?)
According to a recent PC history I read, 1493 (OK I only read half before I could not take anymore), the proper term is "The Triple Alliance."
I kid you not, but I will admit that "The Triple Alliance" reminds me of some 19th Century European power bloc, instead of THE GREATEST CIVILIZATION THE WORLD HAS EVER KNOWN, which is what all right-thinking people know the Aztecs, whoops, I mean The Triple Alliance, was.
The Mayans did do human sacrifices but not on the same scale as the Aztecs. In fact I would guess (though I’m not an expert on pre-Columbus American history) the Aztecs learnt it from the Mayans — the Mayans were the ones who extracted the heart quickly to sacrifice.
