In 1863, Fremont County was established as one of the five original counties of the Idaho Territory. The county was named after the famed explorer and military officer, John C. Fremont. At that time, the main economic activity in the area was fur trading, as the county was strategically located near major fur trapping areas. However, the discovery of gold in the Salmon River and Lemhi Valley in the 1860s brought a rush of prospectors to the region, leading to a sharp increase in population.
Over the next few decades, mining became the dominant industry in Fremont County, with gold, silver, and other minerals being extracted from the hills and mountains. The mining boom brought not only wealth but also a surge in settlement and infrastructural development. Towns such as St. Anthony and Ashton grew rapidly as trading posts, support centers, and transportation hubs. The construction of railroads further facilitated the growth of the mining industry and linked Fremont County to larger markets.
In the early 20th century, the mining industry began to decline, causing a shift in the county's economy. Agriculture and tourism emerged as the new primary economic drivers. The region's fertile soil and favorable climate made it suitable for farming, particularly potato cultivation. Today, Fremont County continues to be an important agricultural region, known for its production of potatoes, grains, livestock, and dairy products. Additionally, the county's scenic beauty and outdoor recreational opportunities make it a popular destination for tourists and outdoor enthusiasts.
