Prince George's County, located on the state's western shore, is bordered on the north by Howard County, the northeast and east by Anne Arundel and Calvert counties, the south by Charles County, and the west and northwest by the District of Columbia, the Potomac River, and Montgomery County. The county was formed from Calvert and Charles counties by Chapter 13, acts of 1695. It is named for Prince George of Denmark, husband of Queen Anne.
Like other southern Maryland counties, tobacco has always been an important crop in Prince George's County. Upper Marlboro, the county seat since 1721, has always been a tobacco marketing center. During the eighteenth century, shallow draft boats carried hogsheads of tobacco from the town down Western Branch to the Patuxent River, where ocean-going vessels anchored. From 1748 until about 1818, all locally grown tobacco was inspected here at a public warehouse before shipment overseas. Today, tobacco is sold at public auction at leaf tobacco auction houses in the county. Tobacco auctions are of prime economic interest to farmers in the area, because within a matter of minutes at auction, a planter's whole income from a crop sown at least 12 months beforehand is determined.
The history of Prince George's County is reflected in the numerous historic houses and sites located in the county. A few of the historic houses to be seen in the county are Bel air Mansion, the home of Samuel Ogle, who served three terms as provincial of Maryland, and his son Benjamin Ogle, governor of Maryland from 1798-1801; Montpelier, one of the famous five part houses in Maryland; and the Surratt House, where in March of 1865 John Surratt and fellow conspirators hid guns and ammunition as part of a plot to kidnap Lincoln. The county is also the home of the University of Maryland College Park campus, Goddard Space Flight Center, and Andrews Air Force Base.
