1. In 1889, Idaho became the 43rd state in the United States. The territory's application for statehood was approved by Congress on July 3, 1890, but November 14 remains an important date in Idaho's history as it marks the day the state officially entered the Union.

2. In 1925, the first electric power transmission line across the Continental Divide was completed near Swan Valley, Idaho. The 93-mile line connected the hydroelectric plant on the Henry's Fork of the Snake River to Montana Power Company's system, opening up new markets for the generation of electricity in the region.

3. On November 14, 1978, the Idaho State Board of Education voted to establish a four-year medical school in Boise, Idaho. Before the establishment of the Idaho College of Osteopathic Medicine in 2016, Idaho was one of only a few states in the country without its own medical school.

4. In 1914, the Barber Dam was completed on the Boise River, creating the first hydroelectric power plant in the state of Idaho. The dam still produces electricity today and is part of the Boise River Greenbelt system of parks and trails.

5. In 1979, the Silver Valley of northern Idaho was declared a Superfund site by the U.S. Environmental Protection Agency due to contamination from mining activities. The cleanup efforts have been ongoing for decades, and today the area is home to a thriving outdoor recreation industry as well as a renewed interest in mining with an emphasis on responsible environmental practices.
