Question

The yakama nation signed major treaties at which 1855 conference

Answer 1

The Treaty of 1855 was signed June 9, 1855, at Camp Stevens in the Walla Walla Valley. The treaty is between the 14 confederated tribes and bands of the Yakama Nation and the United States

Answer 2

The reservation was created in 1855 by a treaty signed by the Governor of the Washington Territory, Isaac Stevens, and representatives of the Yakama tribe. Several native leaders thought that those representatives did not have the authority to cede communal lands and did not obtain a true consensus in the council or in the tribe. A dispute over the treaty led to the Yakima War (1855-1858) against the United States.
