Prince William County, Virginia: History
At the time of European colonization, the native tribes of the area that would become Prince William County were the Doeg, an Algonquian-speaking sub-group of the Powhatan tribal confederation.
When John Smith and other English explorers ventured to the upper Potomac River, beginning in 1608, they recorded the name of a village that the Doeg inhabited as Pemacocack (meaning "plenty of fish" in their language). It was on the west bank of the Potomac River, about 30 miles south of present-day Alexandria. Unable to deal with European diseases and firepower, the Doeg abandoned their villages in the area by 1700.
As population increased in the area, the General Assembly of the colony of Virginia split Stafford County, Virginia in 1730, and added a section which had previously been part of King George County in order to create Prince William County. The county was named for Prince William, Duke of Cumberland, the third son of King George II. The area encompassed by the 1731 act creating Prince William County originally included all of what later became the counties of Arlington, Fairfax, Fauquier, and Loudoun; and the independent cities of Alexandria, Fairfax, Falls Church, Manassas, and Manassas Park.
Fairfax County was split from Prince William County in 1742, and first Loudoun (in 1757) and then the incorporated town of Alexandria (in 1779, part of which later became Arlington County) would later be split from Fairfax County. Fauquier County was created from western Prince William County in 1759.
In 1790, Prince William County's population was 58% white; most of the remainder were enslaved African Americans. The county had been an area of tobacco plantations, but planters were changing to cultivate mixed crops due to soil exhaustion and changes in the market. In the first two decades after the Revolution, the number and percentage of free blacks increased in Virginia as some whites freed their slaves, based on revolutionary ideals.
On March 19, 1892, two white men, Lee Heflin and Joseph Dye, were lynched in Haymarket. They had been convicted of the murder of a girl and sentenced to death, but the mob did not want to wait for the legal system. The men were hung from trees at the edge of woods; then the mob shot into their bodies.
The Washington Post reported, "mob law...is a dangerous thing to encourage. There is too much of it already throughout the country, and it spreads like a contagion so long as public sentiment tacitly approves it." It was unusual that white men were lynched; in Virginia and the rest of the South, black men were overwhelmingly the victims of lynching, the violence by which whites maintained dominance. The county was rural and agricultural for decades. …
