By 1855, the Nimiipuu (Nez Perce) had already seen decades of enormous change. From fur traders to missionaries to settlers who seemed more numerous by the day, outsiders had brought in new customs, products, religions, and ideas. The tribes' leaders reasoned that since the steamrolling of their traditional lifestyle seemed inevitable, it would be in their best interest to reason with the Soyapu (white people) on their own terms. The Nimiipuu feared that if an agreement with the government was not made, their lands would be taken anyway, and they would get nothing in exchange.
When General Isaac Stevens (who was also the first Governor of Washington State) arrived in 1855, eager to acquire land on which to build a transcontinental railway, the Nimiipuu were ready to set the terms of a fair agreement. The council lasted more than a week and several thousand Indians were present, including almost all of Nez Perce nation, and the Wallawallas, Cayuses, Umatillas, Yakamas, and representatives of several other tribes. Eventually they reached a reluctant treaty. The only land the Nimiipuu would have to cede was 7.5 million acres, all of it in border areas. Important ancestral sites were included within the reservation. All traditional Nimiipuu hunting, fishing, and gathering activities would also be allowed to continue indefinitely, even outside the boundaries of their new reservation. In exchange for this trade, the US Government agreed to supply the Nimiipuu with:
The 1855 treaty was an agreement between sovereign nations. Since all 56 Nez Perce tribes had input on and signed the resulting treaty, it became their basic document in dealings with the US Government and legally can still be recognized as such today. Never again was a treaty made that all Nimiipuu agreed to.
