Montana’s state flag was originally designed as a flag for the 1st Montana Infantry to fly during the Spanish-American War in 1898. Since the state had no flag at the time, the infantry commander commissioned a banner to be made with the state seal on a field of dark blue. By the time the unit returned to Montana in 1899, the design had won wide favor with the public and was adopted as the state flag in 1905.

Montana is the only state in the U.S. to share a land border with three Canadian provinces (British Columbia, Alberta, and Saskatchewan).

In 1871, the first inmate was locked up at the Montana Territorial Prison in Deer Lodge, making it the oldest prison in the state.

Montana has many nicknames which predate “Big Sky Country” and “Last Best Place.” Early fur traders described the territory as the “Land of Shining Mountains.” Around 1891, Judge John Wasson Eddy dubbed it the “Bonanza State,” and a book published in 1934 maintains that “Stubtoe State” was a popular nickname (alluding to Montana’s steep mountains). The official nickname, “Treasure State” appeared on a promotional booklet for the Montana Bureau of Agriculture, Labor, and Industry in 1895, referring (of course) to the Montana’s mineral wealth
