Bannock County, located in southeastern Idaho, has a rich and diverse history that stretches back centuries. The area was inhabited by Native American tribes for thousands of years before the arrival of European explorers. In 1805, the Lewis and Clark Expedition passed near the region, interacting with local tribes, and exploring the area’s natural resources. The establishment of Fort Hall by the Hudson’s Bay Company in 1828 further shaped the region’s history, bringing fur traders and influencing trade relationships with Native American communities.

The discovery of gold in the 1860s sparked a significant gold rush, leading to the establishment of mining camps such as Bannock City and Idaho City, which eventually became part of Bannock County. In 1864, Bannock County was officially established by the Idaho Territorial Legislature, with its county seat initially located in the town of Bannock City. However, the county seat was later moved to Pocatello in 1893, which emerged as a vital center of commerce and transportation due to the arrival of the Oregon Short Line Railroad in 1883.

Over the years, Bannock County has witnessed significant developments and transformations. During World War II, Pocatello played a crucial role as a military training and logistics center with the presence of the Pocatello Army Air Base. The county has experienced continued growth and diversification, with the incorporation of the neighboring city of Chubbuck in 1962, contributing to the economic and cultural development of the area.

Today, Bannock County thrives as a vibrant and dynamic region. It is home to the largest city in southeastern Idaho, Pocatello, which serves as a hub for education, healthcare, agriculture, commerce, and outdoor recreational activities. With its scenic landscapes, rich history, and a blend of urban amenities and natural beauty, Bannock County continues to evolve while cherishing its heritage.
