In the early 20th century, Montana was a center of activity for the Industrial Workers of the World (IWW), a radical labor organization that advocated for the overthrow of capitalism and the establishment of a worker-controlled society. The state was the site of several major strikes and labor conflicts during this time, including the Anaconda Road Massacre of 1920, in which striking miners were killed by National Guard troops.
Located in the southern part of the state, Big Horn County in Montana has a rich and diverse history that stretches back thousands of years. The land was initially inhabited by various Native American tribes, including the Crow and Shoshone people, who relied on the area's natural resources for their sustenance and way of life. European settlers began arriving in the mid-1800s, with the establishment of the Montana Territory in 1864.

The discovery of gold in the 1860s brought an influx of miners to the area, leading to the establishment of several mining camps and towns. However, it was the railroad that truly transformed the county, providing a vital transportation link and facilitating trade and development. The completion of the Northern Pacific Railroad through Big Horn County in 1882 further accelerated the region's growth and brought new opportunities.

Agriculture played a significant role in the county's development, with large-scale farming and ranching becoming prevalent. Cattle ranching, in particular, thrived in the vast grasslands of Big Horn County, contributing to the local economy and way of life. The town of Hardin emerged as a key commercial and administrative center, serving as the county seat and providing essential services to the surrounding rural communities.

Over the years, Big Horn County has faced its share of challenges and transformations. The decline of mining and changes in agricultural practices have led to shifts in the local economy. Nevertheless, the county remains a resilient and vibrant community, with a thriving tourism industry focused on its natural beauty and cultural heritage. From its Native American roots to the bustling settlements of the late 19th century, Big Horn County's history is a testament to the resilience and adaptability of its inhabitants.
