1. In 1869, the government established the first post office at Gallatin City, Montana. The town was named after Albert Gallatin, the fourth Secretary of the Treasury, who served under Presidents Thomas Jefferson and James Madison. The post office served as a vital lifeline for communication and commerce, facilitating the growth of the community.

2. In 1874, the first newspaper in the Montana Territory, called The Montana Post, was published in Virginia City. The weekly paper provided news, editorial opinions, and advertising to subscribers across the vast territory. It covered a wide range of topics, from politics and crime to mining and sports, and became a crucial source of information and entertainment for its readers.

3. In 1883, the Northern Pacific Railway completed its tracks across Montana, opening up new opportunities for transportation, commerce, and tourism. The railroad brought people and goods from the East Coast to the West Coast and facilitated the settlement and development of Montana's vast and diverse regions. Some of the towns that grew along the railway, such as Livingston, Bozeman, and Missoula, became hubs of trade, agriculture, education, and culture.

4. In 1906, the Montana Legislature passed the County Unit System, a reform measure aimed at reducing the power of rural counties and increasing the influence of urban centers in state politics. The system created legislative districts based on population, rather than geography, and consolidated smaller counties into larger units. The change had significant consequences for the distribution of political power and the representation of different interests and values in Montana.

5. In 1999, Eric Rudolph, a fugitive wanted for several bombings in the South, was arrested in Murphy, North Carolina, after a five-year manhunt. One of Rudolph's targets was the Olympic Park in Atlanta, Georgia, where a bomb he planted killed one person and injured over a hundred during the 1996 Summer Games. Rudolph also bombed abortion clinics and a lesbian nightclub in other locations. He was eventually sentenced to life in prison without parole and remains one of the most notorious domestic terrorists in American history. While Rudolph's arrest did not happen in Montana, his actions and their impact on national security and civil liberties are relevant to the state and the country.
