History
King George County was established in 1720 when land was split from Richmond County, Virginia. The county is named for King George I of Great Britain. It was substantially reorganized in 1776 and 1777, with land swapped with both Stafford and Westmoreland counties to form the modern boundaries.
In the early decades, planters cultivated tobacco, a labor-intensive commodity crop, depending on the labor of both indentured servants from Britain and enslaved Africans. Gradually slaves became the primary laborers, as fewer indentured servants arrived. Later mixed crops were introduced, as the land had gotten exhausted from tobacco cultivation. The county and state were dominated by slavery.
On March 16, 1751, James Madison, the fourth President of the United States, was born at Belle Grove plantation, the childhood home of his mother, Eleanor Rose "Nellie" Conway. Like other women, she returned home to her mother for assistance when bearing her child. The plantation is located in Port Conway in southern King George County. Nellie Conway was the daughter of its owner, Francis Conway, for whom the town of Port Conway was named. William "Extra Billy" Smith, twice elected governor of Virginia, was born at Marengo, Virginia in 1797.
On May 1, 1861, during the American Civil War, Confederates installed artillery at Mathias Point in order to blockade the Potomac River. On June 27, the steamer Thomas Freeborn bombarded Mathias Point in an effort to drive away the soldiers who were manning the weapons. Confederate soldiers fired back from Mathias Point, striking and mortally wounding Commander James H. Ward of the Freeborn. He was the first Union naval officer to die in the Civil War.
