sioux nation

doing a book summary for my school, reviewing sometimes unbelieveable u.s. history.
here is chief red cloud.

did you know that at one time, there were over 60 MILLION bison roaming the great plains?
and that by the time the late 1800s rolled around,
after all of the horrible, careless things white people did to native americans and their way of life,
there were only about 200 left?
