In the mid-19th century, the policy against Native Americans was such that US government officials decided to attack the bison, one of the animals that represented the main source of food and protein for the natives.

Explanation:

Although the bison is one of the emblematic animals of the country, at that time there was little consideration for its existence, so among sport hunting, the fur and meat trade and the hunting of natives, this animal was thrown into danger of extinction, since it was considered that every bison that died, was an American Indian also dead.
