When Europeans started to colonize the Americas and laid claims on American lands and resources, they were bound to conflict with Natives. After the Homestead Act was passed in the US, the settlers started to move westward in Large numbers. During the 1870s United States Army was at war with Native Tribes. California Goldrush also led to the loss of native lands and a decrease in the land and resources for the natives. This brought them in conflict with whites.

During westward expansion, they settled in Dakota, Utah and Wyoming Settlers and Cattle ranchers pushed them out of their homelands. The tribes of plains did not want the Whites to cross their hunting lands and tried to destroy the wagons bound for California and Oregon.
