The treaty was negotiated after investigation by the Indian Peace Commission, which in its final report in 1868 concluded that the wars had been preventable.

He was likely born into the Nokoni ("Wanderers") band of Tabby-nocca and grown up among the Kwahadis, the son of Kwahadi Comanche chief Peta Nocona and Cynthia Ann Parker, an Anglo-American who had been kidnapped as a child and assimilated into the Nokoni tribe. Following the apprehension of several Kiowa chiefs in 1871, Quanah Parker emerged as a dominant figure in the Red River War, clashing repeatedly with Colonel Ranald S. Mackenzie. With European-Americans hunting American bison, the Comanches' primary sustenance, into near extinction, Quanah Parker eventually surrendered and peaceably led the Kwahadi to the reservation at Fort Sill, Oklahoma.

The Red River War was a military campaign launched by the United States Army in 1874 to displace the Comanche, Kiowa, Southern Cheyenne, and Arapaho Native American tribes from the Southern Plains, and forcibly relocate the tribes to reservations in Indian Territory. Lasting only a few months, the war had several army columns crisscross the Texas Panhandle in an effort to locate, harass, and capture highly mobile Native American bands. Most of the engagements were small skirmishes in which neither side suffered many casualties. The war wound down over the last few months of 1874, as fewer and fewer Indian bands had the strength and supplies to remain in the field. Though the last significantly sized group did not surrender until mid-1875, the war marked the end of free-roaming Indian populations on the southern Great Plains.
