A history page for Prince William County
This page tells more about the naming of the county and the history of its namesake.

The first white men to arrive in the county area was Captain John Smith and his group who came along the Potomac River in 1608. It wasn't until 1731 that the county was officially formed. It was named for William Augustus, Duke of Cumberland, second son of King George II. The area was reduced in 1759 to the current size. The original area included what would later become Arlington, Alexandria, Fairfax, Fauquier and Loudoun Counties.

The county has a large role in the Civil War. The area called Manassas Junction was a little community of only four structures. It was also known as Tudor Hall, the name of the post office. This area was the site of a great battle in July, 1861. The Manassas National Battlefield Park tells the story. Other important events in the Civil War also occurred in other areas of the county.

When the county courthouse was built in 1822, the County Seat became Brentsville. The town has always been a major crossroads from the Potomac River to the Blue Ridge Mountains. The seat was moved to Manassas in 1892.
