The Bitterroot Salish peoples are a Salish-speaking group of Native Americans, and one of three tribes of the Confederated Salish and Kootenai Tribes of the Flathead Nation in Montana. The Flathead Reservation is also home to the Kootenai and Pend d'Oreilles tribes. Bitterroot Salish Peoples or Flathead originally lived in an area west of Billings, Montana, extending to the continental divide in the west and south of Great Falls, Montana extending to the Montana–Wyoming border. From there they later moved west into the Bitterroot Valley. By request, a Catholic mission was built there in 1841. In 1891 they were forcibly moved to the Flathead Reservation.
