Montana State Flower - Bitterroot
The United States acquired the area of Montana from France as part of the Louisiana Purchase in 1803 and by a treaty with Great Britain in 1846. Montana Territory was organized from the northeastern part of Idaho Territory on May 26, 1864, with generally the same boundary as the present state.
Census data for Montana are available beginning with the 1870 census. The 1860 census population in present-day Montana was included in unorganized Dakota, although legally the area was within Nebraska and Washington territories. The portion of Yellowstone National Park in Montana was probably enumerated as part of Wyoming from 1880 to 1910.
Data for the legally established state of Montana are available beginning with the 1890 census.
