Various indigenous peoples have lived in the territory of the present-day state of Montana for thousands of years. Historic tribes encountered by Europeans and settlers from the United States included the Crow in the south-central area, the Cheyenne in the southeast, the Blackfeet, Assiniboine, and Gros Ventres in the central and north-central area, and the Kootenai and Salish in the west. The smaller Pend d’Oreille and Kalispel tribes lived near Flathead Lake and the western mountains, respectively. A part of southeastern Montana was used as a corridor between the Crows and the related Hidatsas in North Dakota.
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, Confederate Gulch, Silver Bow, Emigrant Gulch, and Cooke City. Gold output between 1862 and 1876 reached $144 million, after which silver became even more important. The largest mining operations were at Butte, with important silver deposits and expansive copper deposits.
Before the creation of Montana Territory (1864–1889), areas within present-day Montana were part of the Oregon Territory (1848–1859), Washington Territory (1853–1863), Idaho Territory (1863–1864), and Dakota Territory (1861–1864). Montana Territory became one of the territories of the United States on May 26, 1864. The first territorial capital was located at Bannack. Sidney Edgerton served as the first territorial governor. The capital moved to Virginia City in 1865 and to Helena in 1875. In 1870, the non-Indian population of the Montana Territory was 20,595. The Montana Historical Society, founded on February 2, 1865, in Virginia City, is the oldest such institution west of the Mississippi (excluding Louisiana). In 1869 and 1870 respectively, the Cook–Folsom–Peterson and the Washburn–Langford–Doane Expeditions were launched from Helena into the Upper Yellowstone region. The extraordinary discoveries and reports from these expeditions led to the creation of Yellowstone National Park in 1872.
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 Red Cloud’s War, the Great Sioux War of 1876, and the Nez Perce War and in conflicts with Piegan Blackfeet. The most notable were the Marias Massacre (1870), Battle of the Little Bighorn (1876), Battle of the Big Hole (1877), and Battle of Bear Paw (1877). The last recorded conflict in Montana between the U.S. Army and Native Americans occurred in 1887 during the Battle of Crow Agency in the Big Horn country. Native survivors who had signed treaties were generally required to move onto reservations.
Simultaneously with these conflicts, bison, a keystone species and the primary protein source that Native people had survived on for many centuries, were being destroyed. Experts estimate that around 13 million bison roamed Montana in 1870. In 1875, General Philip Sheridan pleaded to a joint session of Congress to authorize the slaughtering of bison herds to deprive Native people of their source of food. By 1884, commercial hunting had brought bison to the verge of extinction; only about 325 bison remained in the entire United States.
Cattle ranching has been central to Montana’s history and economy since Johnny Grant began wintering cattle in the Deer Lodge Valley in the 1850s and traded cattle fattened in fertile Montana valleys with emigrants on the Oregon Trail.Nelson Story brought the first Texas Longhorn cattle into the territory in 1866.Granville Stuart, Samuel Hauser, and Andrew J. Davis started a major open-range cattle operation in Fergus County in 1879. The Grant-Kohrs Ranch National Historic Site in Deer Lodge is maintained today as a link to the ranching style of the late 19th century. Operated by the National Park Service, it is a 1,900-acre (7.7 km2) working ranch.
Tracks of the Northern Pacific Railroad (NPR) reached Montana from the west in 1881 and from the east in 1882. However, the railroad played a major role in sparking tensions with Native American tribes in the 1870s. Jay Cooke, the NPR president, launched major surveys into the Yellowstone valley in 1871, 1872, and 1873, which were challenged forcefully by the Sioux under chief Sitting Bull. These clashes, in part, contributed to the Panic of 1873, a financial crisis that delayed the construction of the railroad into Montana. Surveys in 1874, 1875, and 1876 helped spark the Great Sioux War of 1876. The transcontinental NPR was completed on September 8, 1883, at Gold Creek.
In 1881, the Utah and Northern Railway, a branch line of the Union Pacific, completed a narrow-gauge line from northern Utah to Butte. A number of smaller spur lines operated in Montana from 1881 into the 20th century, including the Oregon Short Line, Montana Railroad, and Milwaukee Road.
Tracks of the Great Northern Railroad (GNR) reached eastern Montana in 1887 and when they reached the northern Rocky Mountains in 1890, the GNR became a significant promoter of tourism to Glacier National Park region. The transcontinental GNR was completed on January 6, 1893, at Scenic, Washington and is known as the Hi Line, being the northern most transcontinental rail line in the United States.
Under Territorial Governor Thomas Meagher, Montanans held a constitutional convention in 1866 in a failed bid for statehood. A second constitutional convention held in Helena in 1884 produced a constitution ratified 3:1 by Montana citizens in November 1884. For political reasons, Congress did not approve Montana statehood until February 1889 and President Grover Cleveland signed an omnibus bill granting statehood to Montana, North Dakota, South Dakota, and Washington once the appropriate state constitutions were crafted. In July 1889, Montanans convened their third constitutional convention and produced a constitution accepted by the people and the federal government. On November 8, 1889, President Benjamin Harrison proclaimed Montana the union’s 41st state. The first state governor was Joseph K. Toole. In the 1880s, Helena (the state capital) had more millionaires per capita than any other United States city.
The Homestead Act of 1862 provided free land to settlers who could claim and “prove-up” 160 acres (0.65 km) of federal land in the Midwest and western United States. Montana did not see a large influx of immigrants from this act because 160 acres were usually insufficient to support a family in the arid territory. The first homestead claim under the act in Montana was made by David Carpenter near Helena in 1868. The first claim by a woman was made near Warm Springs Creek by Gwenllian Evans, the daughter of Deer Lodge Montana pioneer, Morgan Evans. By 1880, farms were in the more verdant valleys of central and western Montana, but few were on the eastern plains.
The Desert Land Act of 1877 was passed to allow settlement of arid lands in the west and allotted 640 acres (2.6 km) to settlers for a fee of $.25 per acre and a promise to irrigate the land. After three years, a fee of one dollar per acre would be paid and the settler would own the land. This act brought mostly cattle and sheep ranchers into Montana, many of whom grazed their herds on the Montana prairie for three years, did little to irrigate the land and then abandoned it without paying the final fees. Some farmers came with the arrival of the Great Northern and Northern Pacific Railroads throughout the 1880s and 1890s, though in relatively small numbers.
In the early 1900s, James J. Hill of the Great Northern began to promote settlement in the Montana prairie to fill his trains with settlers and goods. Other railroads followed suit. In 1902, the Reclamation Act was passed, allowing irrigation projects to be built in Montana’s eastern river valleys. In 1909, Congress passed the Enlarged Homestead Act that expanded the amount of free land from 160 to 320 acres (0.6 to 1.3 km2) per family and in 1912 reduced the time to “prove up” on a claim to three years. In 1916, the Stock-Raising Homestead Act allowed homesteads of 640 acres in areas unsuitable for irrigation. This combination of advertising and changes in the Homestead Act drew tens of thousands of homesteaders, lured by free land, with World War I bringing particularly high wheat prices. In addition, Montana was going through a temporary period of higher-than-average precipitation. Homesteaders arriving in this period were known as “Honyockers”, or “scissorbills”. Though the word “honyocker”, possibly derived from the ethnic slur “hunyak”, was applied in a derisive manner at homesteaders as being “greenhorns”, “new at his business”, or “unprepared”, most of these new settlers had farming experience, though many did not.
However, farmers faced a number of problems. Massive debt was one. Also, most settlers were from wetter regions, unprepared for the dry climate, lack of trees, and scarce water resources. In addition, small homesteads of fewer than 320 acres (130 ha) were unsuited to the environment. Weather and agricultural conditions are much harsher and drier west of the 100th meridian. Then, the droughts of 1917–1921 proved devastating. Many people left, and half the banks in the state went bankrupt as a result of providing mortgages that could not be repaid. As a result, farm sizes increased while the number of farms decreased.
By 1910, homesteaders filed claims on over five million acres, and by 1923, over 93 million acres were farmed. In 1910, the Great Falls land office alone had more than a thousand homestead filings per month, and at the peak of 1917–1918 it had 14,000 new homesteads each year. Significant drops occurred following the drought in 1919.
As World War I broke out, Jeannette Rankin, representative of Montana and the first woman in the United States to be a member of Congress, voted against the United States’ declaration of war. Her actions were widely criticized in Montana, where support for the war and patriotism was strong. In 1917–18, due to a miscalculation of Montana’s population, about 40,000 Montanans, 10% of the state’s population, volunteered or were drafted into the armed forces. This represented a manpower contribution to the war that was 25% higher than any other state on a per capita basis. Around 1500 Montanans died as a result of the war and 2437 were wounded, also higher than any other state on a per capita basis. Montana’s Remount station in Miles City provided 10,000 cavalry horses for the war, more than any other Army post in the country. The war created a boom for Montana mining, lumber, and farming interests, as demand for war materials and food increased.
In June 1917, the U.S. Congress passed the Espionage Act of 1917, which was extended by the Sedition Act of 1918. In February 1918, the Montana legislature had passed the Montana Sedition Act, which was a model for the federal version. In combination, these laws criminalized criticism of the U.S. government, military, or symbols through speech or other means. The Montana Act led to the arrest of more than 200 individuals and the conviction of 78, mostly of German or Austrian descent. More than 40 spent time in prison. In May 2006, then-Governor Brian Schweitzer posthumously issued full pardons for all those convicted of violating the Montana Sedition Act.
The Montanans who opposed U.S. entry into the war included immigrant groups of German and Irish heritage, as well as pacifist Anabaptist people such as the Hutterites and Mennonites, many of whom were also of Germanic heritage. In turn, pro-War groups formed, such as the Montana Council of Defense, created by Governor Samuel V. Stewart and local “loyalty committees”.
War sentiment was complicated by labor issues. The Anaconda Copper Company, which was at its historic peak of copper production, was an extremely powerful force in Montana, but it also faced criticism and opposition from socialist newspapers and unions struggling to make gains for their members. In Butte, a multiethnic community with a significant European immigrant population, labor unions, particularly the newly formed Metal Mine Workers’ Union, opposed the war on grounds it mostly profited large lumber and mining interests. In the wake of ramped-up mine production and the Speculator Mine disaster in June 1917,Industrial Workers of the World organizer Frank Little arrived in Butte to organize miners. He gave some speeches with inflammatory antiwar rhetoric. On August 1, 1917, he was dragged from his boarding house by masked vigilantes, and hanged from a railroad trestle, considered a lynching. Little’s murder and the strikes that followed resulted in the National Guard being sent to Butte to restore order. Overall, anti-German and antilabor sentiment increased and created a movement that led to the passage of the Montana Sedition Act the following February. In addition, the Council of Defense was made a state agency with the power to prosecute and punish individuals deemed in violation of the Act. The council also passed rules limiting public gatherings and prohibiting the speaking of German in public.
In the wake of the legislative action in 1918, emotions rose. U.S. Attorney Burton K. Wheeler and several district court judges who hesitated to prosecute or convict people brought up on charges were strongly criticized. Wheeler was brought before the Council of Defense, though he avoided formal proceedings, and a district court judge from Forsyth was impeached. Burnings of German-language books and several near-hangings occurred. The prohibition on speaking German remained in effect into the early 1920s. Complicating the wartime struggles, the 1918 influenza epidemic claimed the lives of more than 5,000 Montanans. The suppression of civil liberties that occurred led some historians to dub this period “Montana’s Agony”.
An economic depression began in Montana after World War I and lasted through the Great Depression until the beginning of World War II. This caused great hardship for farmers, ranchers, and miners. The wheat farms in eastern Montana make the state a major producer; the wheat has a relatively high protein content, thus commands premium prices.
By the time the U.S. entered World War II on December 8, 1941, many Montanans had enlisted in the military to escape the poor national economy of the previous decade. Another 40,000-plus Montanans entered the armed forces in the first year following the declaration of war, and more than 57,000 joined up before the war ended. These numbers constituted about ten percent of the state’s population, and Montana again contributed one of the highest numbers of soldiers per capita of any state. Many Native Americans were among those who served, including soldiers from the Crow Nation who became Code Talkers. At least 1,500 Montanans died in the war. Montana also was the training ground for the First Special Service Force or “Devil’s Brigade”, a joint U.S-Canadian commando-style force that trained at Fort William Henry Harrison for experience in mountainous and winter conditions before deployment. Air bases were built in Great Falls, Lewistown, Cut Bank, and Glasgow, some of which were used as staging areas to prepare planes to be sent to allied forces in the Soviet Union. During the war, about 30 Japanese Fu-Go balloon bombs were documented to have landed in Montana, though no casualties nor major forest fires were attributed to them.
In 1940, Jeannette Rankin was again elected to Congress. In 1941, as she had in 1917, she voted against the United States’ declaration of war after the Japanese attack on Pearl Harbor. Hers was the only vote against the war, and in the wake of public outcry over her vote, Rankin required police protection for a time. Other pacifists tended to be those from “peace churches” who generally opposed war. Many individuals claiming conscientious objector status from throughout the U.S. were sent to Montana during the war as smokejumpers and for other forest fire-fighting duties.
In 1942, the US Army established Camp Rimini near Helena for the purpose of training sled dogs in winter weather.
During World War II, the planned battleship USS Montana was named in honor of the state but it was never completed. Montana is the only one of the first 48 states lacking a completed battleship being named for it. Alaska and Hawaii have both had nuclear submarines named after them. Montana is the only state in the union without a modern naval ship named in its honor. However, in August 2007, Senator Jon Tester asked that a submarine be christened USS Montana. Secretary of the Navy Ray Mabus announced on September 3, 2015, that Virginia Class attack submarine SSN-794 will become the second commissioned warship to bear the name.
In the post-World War II Cold War era, Montana became host to U.S. Air Force Military Air Transport Service (1947) for airlift training in C-54 Skymasters and eventually, in 1953 Strategic Air Command air and missile forces were based at Malmstrom Air Force Base in Great Falls. The base also hosted the 29th Fighter Interceptor Squadron, Air Defense Command from 1953 to 1968. In December 1959, Malmstrom AFB was selected as the home of the new Minuteman I intercontinental ballistic missile. The first operational missiles were in place and ready in early 1962. In late 1962, missiles assigned to the 341st Strategic Missile Wing played a major role in the Cuban Missile Crisis. When the Soviets removed their missiles from Cuba, President John F. Kennedy said the Soviets backed down because they knew he had an “ace in the hole”, referring directly to the Minuteman missiles in Montana. Montana eventually became home to the largest ICBM field in the U.S. covering 23,500 square miles (61,000 km).
