Petersburg was formed from parts of Dinwiddie, Prince George, and Chesterfield counties. A garrison and fur trading post called Fort Henry was established in 1645 on the site of the Indian village of Appamattuck. The present name, suggested in 1733 by William Byrd II, honors Peter Jones, Byrd's companion on expeditions into the Virginia backcountry. Petersburg was established in 1748 and incorporated as a town in 1784. In the latter year the towns of Blandford, Pocahontas, and Ravenscroft were added to Petersburg. It was incorporated as a city in 1850. Petersburg was enlarged by annexation from both Prince George and Dinwiddie counties in 1972.
