Pretty substantial numbers to me....

"This Native American depopulation occurred during the contact period, causing the Native American population size to decline from 1-18 million before European contact (c. AD 1500) to an estimated 530,000 by 1900."

As a bit of background, Spanish invaders battled 19 years to conquer the Maya in the Yucatán Peninsula. Unlike the Aztecs in central Mexico who succumbed to Cortez in less than two years, the Mayans were not easily overtaken. But by 1700, a once robust Maya population had fallen to 150,000 due to disease, displacement and famine
I can remember annoying my history teachers when stuff like that came up. :evil_lol:
Estimated statistics arn't really all that accurate for those periods. Especially considering that in those cases the Europeans were trying to wipe out those cultures. They didn't really want it to look vindictive (and from their point of view maybe they didn't see it that way back then) but the end result was that there was no 'accidental' disease or famine with half the contacts back then. There were actually attempts to spread disease and famine to get the natives out of the way (especially the ones that were difficult to conquer).
