About Yellowstone County

Yellowstone County is located in the state of Montana and has a rich history that dates back thousands of years. Native American tribes such as the Crow and Shoshone-Bannock inhabited the region long before European settlers arrived. The Lewis and Clark Expedition passed through the area in 1806, noting the breathtaking landscapes and abundant wildlife. In the mid-1800s, fur trappers and traders began exploring the region more extensively.

The discovery of gold in Montana in the 1860s brought a wave of settlers to the area, including Yellowstone County. The county was officially established in 1883 and was named after the nearby Yellowstone River, which runs through the region. Throughout this period, the Native American populations were pushed out of their ancestral lands and onto reservations.

Yellowstone County experienced significant growth during the late 19th and early 20th centuries. The arrival of the Northern Pacific Railway in 1882 spurred economic development and the establishment of several towns, including Billings, which would become the county seat. Agriculture and ranching became prominent industries in the region, taking advantage of the fertile land and natural resources.

In the 20th century, Yellowstone County continued to grow, with industries diversifying and expanding. The discovery of oil in the 1920s led to the establishment of oil refineries and boosted the local economy.
