He was the progenitor of the Breckinridge political family. Born in Staunton, Virginia, Breckinridge attended William and Mary College where he was taught by George Wythe. He was first elected to the Virginia legislature when he was only 19 years old and still a student, but because he was underage, he was not allowed to serve until his third term. Breckinridge served in the Virginia militia during the American Revolutionary War. Afterwards he studied law, and began a private practice in Charlottesville, Virginia. He was elected to the United States Congress, but resigned in 1792 before his term even began. In 1793 he moved to Lexington, Kentucky and began to practice law there. He purchased 2,467 acres of land and established a horse breeding operation that would become Castleton Farm, one of the most famous names in American horse racing history
