By 1855, the nimíipuu (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 nimíipuu 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 nimíipuu 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 nimíipuu 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 nimíipuu 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 nimíipuu with:
The idea of most of these provisions was that within 20 years, the tribes would learn the skills necessary to thrive in the new American world while still retaining the most important aspects of their own culture. No whites besides the above-mentioned employees and the Indian Agent would be allowed on the reservation without the consent of the tribal leaders.
