The Nez Perce War of 1877 pitted several bands of the Nez Perce tribe of Native Americans and their allies against the United States Army. Fought between June and October, the conflict stemmed from the refusal of several bands of the Nez Perce, dubbed “non-treaty Indians,” to give up their ancestral lands in the Pacific Northwest and move to an Indian reservation in the Idaho Territory. This forced removal was a violation of the 1855 Treaty of Walla Walla, which granted the tribe 7.5 million acres of their ancestral lands and the right to hunt and fish on lands ceded to the U.S. government.
