The correct answer to this open question is the following.
My narrative account analyzing the conflict between the Plains Indians and the US government in the years 1876-90 begin like this.
In a time where white settlers wanted more land to exploit the natural resources of the earth, the Native American Indian tribes tried desperately to fight for their lands.
Both sides had completely different approaches to nature. White settlers wanted more land to make a profit from the many raw materials and natural resources found in these regions. On the other hand, the Native American Indians knew that those territories were theirs, inherited by their ancestors. They honored the land to thank Mother Nature for the many benefits they received. That is why they offered dances and chants to nature.
As we now, Native American Indians were removed from their lands and many US legislation was created to make it legal. However, it was not an easy process. It was full of battles, blood, and tears. For instance, we have the case of the Battle of the Little Bighorn in 1876) or the Ghost Dance in 1890.
