Born to a band of Northern Arapaho in present-day Wyoming, Des-che-wa-wah (Runs On Top) endured a series of harrowing tragedies against the brutal backdrop of the nineteenth-century Indian Wars. As a boy he experienced the merciless killings of his family in vicious raids and attacks, surviving only to be given up by his starving mother to U.S. officers stationed at a western military base. Des-che-wa-wah was eventually adopted by a sympathetic infantry lieutenant who changed his name and set his life on a radically different course.

Over the next sixty years Coolidge inhabited western plains and eastern cities, rode in military campaigns against the Lakota, entered the Episcopal priesthood, labored as missionary to his tribe on the Wind River Reservation, fomented dangerous conspiracies, married a wealthy New York heiress, met with presidents and congressmen, and became one of the nation's most prominent Indigenous persons as leader of the Native-run reform group the Society of American Indians. Coolidge's fascinating biography is essential for understanding the myriad ways Native Americans faced modernity at the turn of the century.
