Question

What caused the great number of native American deaths?

Answer 1

Native American deaths were mainly caused by the introduction of new diseases and weapons brought mainly by Europeans.

Answer 2

The deaths were caused by the diseases that where brought over from far away places. I also heard that people from far way places brought weapons to kill the native Americans because the native people didn't want to move because they though they were native ( which they are lol) Hope this helps!
