Montana is not just a beautiful state; it’s also a state filled to the brim with rich history, notable moments, and more. Some of the most important historic events in Montana include when, in 1795, the Yellowstone River was officially named. In 1803, the United States acquired most of Montana in the Louisiana Purchase, and in 1846, the Oregon Treaty would hand over the rest of the state as well. In 1889, Montana officially became a state. In 1910, Congress officially established Glacier National Park.

In 1863, a Montana lawman became the first to die in the line of duty in Virginia City, killed by two other deputies in broad daylight and cold blood. In December of that year, more than 102 people were killed and more than a quarter-million dollars (in 1863 dollars) was stolen by the “Road Agents” gang led by Henry Plummet. Plummet was hanged in 1864. In 1877, copper mining – lots of it – began in Butte. In 1910, devastating forest fires ripped through western Montana.
