Why were the Sioux enemies with Nez Perce?

The Sioux and Nez Perce were often in conflict due to competition over territory and resources, particularly in the context of hunting and fishing grounds. The Sioux, primarily located in the Great Plains, sought to expand their influence and control over areas that the Nez Perce, from the Pacific Northwest, traditionally utilized. These tensions were exacerbated by the broader impact of European-American expansion, which intensified rivalries among Native American tribes. Additionally, cultural differences and alliances with other tribes further fueled hostilities between them.
