Ravalli County was once home to the Bitterroot Salish Indian Tribe. The tribe was first encountered in 1805 by the
Lewis and Clark Expedition, which noted the friendly nature of the tribe. The Roman Catholic Church took interest in
creating a mission in the area, and in 1841, Stevensville was founded. In 1891, the Salish tribe was relocated to the
current Flathead reservation under the Treaty of Hellgate.
In 1877, Chief Joseph and his tribe of Nez Perce passed through Ravalli county on their way to Canada in order to escape
confinement to a reservation.
Ravalli County was created by the Montana Legislature on March 3, 1893 from Missoula County. It is named after the Italian Jesuit priest
Father Antony Ravalli, who came to the Bitterroot valley in 1845.
