As the title states, colonialists used diseases such as smallpox or influenza to kill the natives, and quite effectively at that.
However, I'm wondering if the natives used the diseases they have antibodies to(I am assuming there are illnesses native to certain tribes) as a counter the colonialist bio warfare, OR even if such a thing would be possible
Thanks in advance for any responses
/u/anthropology_nerd has previously answered When Europeans brought diseases to the New World, how come Europeans themselves didn't get sick from diseases specific to the New World?
This topic was addressed broadly during anthropology_nerd's series MYTHS OF CONQUEST for /r/badhistory in the entry "Death by Disease Alone".
