Question

why did native Americans suffer from smallpox ??? (as per ch 4 history class 10)​

Answer 1

Because Native American populations were not previously exposed to most diseases introduced by European colonists, populations rarely had built up individual or population immunities to those diseases. Therefore, the diseases affected, and often continue to affect, them more strongly than their European carriers.

summary

as Americans doesn't have proper immunity measures and Britisher s used it as weapon and thus controles america
