Idaho played a key role in the development of atomic energy. During World War II, the federal government established the Idaho National Laboratory in eastern Idaho, which was used to research and develop nuclear technology. Today, the lab is one of the leading research facilities in the world for nuclear energy and other forms of advanced technology.
Ada County is located in southwestern Idaho and was established in 1864. It is named after Ada Riggs, daughter of the first settler in the area, H.C. Riggs. The region was originally inhabited by the Shoshone and Bannock Native American tribes. In the early 1800s, European fur traders and explorers began to arrive in the area.

The discovery of gold in the Boise Basin in the 1860s led to a population boom in Ada County and its county seat, Boise City. The area became a major supply center for miners, and many settlers moved to the county in search of prosperity. Agriculture also thrived in the fertile Boise River Valley, with farmers growing crops such as potatoes, grains, and orchard fruits.

In the late 19th and early 20th centuries, Ada County experienced significant growth and development. The completion of the Oregon Short Line Railroad in 1887 boosted the local economy, opening up new markets for agricultural products and facilitating transportation. The city of Boise became a regional economic hub, attracting businesses, government institutions, and educational facilities.

Throughout the 20th century, Ada County continued to grow, with an increasing population and expanding infrastructure. The county's economy diversified, and industries such as manufacturing, technology, and healthcare emerged. Today, Ada County is known for its thriving economy, outdoor recreational opportunities, and vibrant cultural scene, making it a desirable place to live and visit in Idaho.
