Etymology
The name Montana comes from the Spanish word ''montaña'', which in turn comes from the Latin word ''montanea'', meaning "mountain" or more broadly "mountainous country."
''Montaña del Norte'' was the name given by early Spanish explorers to the entire mountainous region of the west. The name Montana was added in 1863 to a bill by the

The first gold discovered in Montana was at
Gold Creek near present-day
Garrison in 1852. Gold rushes to the region commenced in earnest starting in 1862. A series of major mineral discoveries in the western part of the state found gold, silver, copper, lead, and coal (and later oil) which attracted tens of thousands of miners to the area. The richest of all gold placer diggings was discovered at Alder Gulch, where the town of
Virginia City was established. Other rich placer deposits were found at Last Chance Gulch, where the city of Helena now stands,

Conflicts
As settlers began populating Montana from the 1850s through the 1870s, disputes with Native Americans ensued, primarily over land ownership and control. In 1855, Washington Territorial Governor
Isaac Stevens negotiated the
Hellgate treaty between the United States government and the Salish, Pend d'Oreille, and Kootenai people of western Montana, which established boundaries for the tribal nations. The treaty was ratified in 1859. While the treaty established what later became the
Flathead Indian Reservation

, trouble with interpreters and confusion over the terms of the treaty led Whites to believe the Bitterroot Valley was opened to settlement, but the tribal nations disputed those provisions. The Salish remained in the Bitterroot Valley until 1891.
The first U.S. Army post established in Montana was
Camp Cooke in 1866, on the Missouri River, to protect steamboat traffic to Fort Benton. More than a dozen additional military outposts were established in the state. Pressure over land ownership and control increased due to discoveries of gold in various parts of Montana and surrounding states. Major battles occurred in Montana during
