History and Facts of United States Counties
Counties were among the earliest units of local government established in the 13 Colonies that would become the United States. The first colonial counties were established in Virginia in 1634. The other colonies established county governments shortly after Virginia.
Originally counties were placed so that a county seat would be no more than a day’s journey for everyone within the county borders.
However, today more recent U.S. counties have no restrictions on size or population.
