Stevensville is officially recognized as the first permanent settlement in the state of Montana. Forty-eight years before Montana became the nation’s 41st state, Stevensville was settled by Jesuit Missionaries at the request of the Bitter Root Salish Indians.
Through interactions with Iroquois Indians between 1812 and 1820, the Bitter Root Salish Indians leaned about Christianity and Jesuit Missionaries (blackrobes) that worked with Indian tribes teaching about agriculture, medicine, and religion. Interest in these “blackrobes” grew among the Salish and, in 1831, four young Salish men were dispatched to St. Louis, Missouri to request a “blackrobe” to return with them to their homeland of present day Stevensville. The four Salish men were directed to the home and office of William Clark (of Lewis and Clark fame) to make their request. At that time Clark was in charge of administering the territory they called home. Through the perils of their trip two of the Indians died at the home of General Clark. The remaining two Salish men secured a visit with St. Louis Bishop Joseph Rosati who assured them that missionaries would be sent to the Bitter Root Valley when funds and missionaries were available in the future.
Again in 1835 and 1837 the Bitter Root Salish dispatched men to St. Louis to request missionaries but to no avail. Finally in 1839 a group of Iroquois and Salish met Father Pierre-Jean DeSmet in Council Bluff, IA. The meeting resulted in Fr. DeSmet promising to fulfill their request for a missionary the following year.
DeSmet arrived in present day Stevensville on September 24, 1841 and called the settlement St. Mary’s. Construction of a chapel immediately began followed by other permanent structures including log cabins and Montana’s first pharmacy.
In 1850 Major John Owen arrived in the valley and set up camp north of St. Mary’s. In time, Major Owen established a trading post and military strong point named Fort Owen, which served the settlers, Indians, and missionaries in the valley.
The name of the settlement was changed from St. Mary's to Stevensville in 1864 to honor territorial governor Isaac Ingle Stevens. In the words of Luther E. Stanley, "When Isaac Ingle Stevens was ordered to Fort Owen in 1853, he came to what he supposed would be a military fort but much to his surprise, it was a trading post. General Stevens, for the past year, had been in charge of military operations and Indian affairs in the Northwest Territory...he moved his government and military material to Fort Owen. This fort became the territorial capital in 1853 and served that until 1858, when Stevens was called back to active duty with the Union Army. He was killed in action in 1862 at Chantilly....Stevens laid out a new town near the ruins of St. Mary's Mission and Fort Owen...It was named Stevensville in his honor and authorized by President Lincoln on May 12, 1864."
