George Washington was first and foremost a Virginian. Born in the state's Tidewater region, he was reared near Fredericksburg and took up residence at Mount Vernon along the Potomac River. As a young surveyor, he worked in Virginia's backcountry. He began his military career as a Virginia militia officer on the colony's frontier. The majority of his widespread landholdings were in his native state, and his entrepreneurial endeavors ranged from the swamplands of the Southeast to the upper Potomac River Valley. Historian John Maass explores the numerous sites all over the Commonwealth associated with Washington and demonstrates their lasting importance.
