Russell County was formed in 1786 from a portion of Washington County. It was named for Col. William Russell, who assisted in the drafting of the Declaration of Independence. Early settlers, who were mostly English and Scotch-Irish, endured geographic isolation as they shaped the ways of life, attitudes, products, legends, and realities that would ultimately usher Russell County into the information age of the 21st century. In 1774, Daniel Boone led the defense of the Clinch River settlements during Dunmore's War, the war between the colony of Virginia and the Shawnee and Mingo Indians. The Virginia-led attack was designed to remove the last obstacle to colonial conquest of the area. By 1858, Russell County had been reduced from 3,000 square miles to 483 square miles. Other counties formed from all or part of Russell were Lee, Tazewell, Scott, and Buchanan. A portion of what is now West Virginia was within the original boundaries of Russell County. The county seat, Lebanon, is a vibrant destination for industry and technology.
