Marker text: PRINCE WILLIAM COUNTY
Prince William County, named for William Augustus, Duke of Cumberland and third son of King George II, was offically formed from Stafford and King George Counties in 1731. Manassas was designated the county seat in 1892. Previously the county seat had been located at Occoquan Creek, Cedar Run, Dumfries, and Brentville. The two battles of Manassas took place here on 21 July 1861 and 28-30 August 1862. Both battles resulted in Confederate victories over the Union army. Several sites here are listed on the National Register of Historic Places, including Rippon LOdge, the Weems-Botts House, and Bel Air.
