The Appamattuck were the first people documented as living at the current site of Petersburg. In 1607 John Smith met the "young and comely" Opossunoquonuske, the female chief (weroansqua) who owed allegiance to Powhatan as a member of his paramount chiefdom. By 1610, the colonists and Appamattuck were no longer friendly traders. After a group of colonists were killed by Opossunoquonuske's warriors, the colonists burned the town. In 1611, Sir Thomas Dale located Henricus nearby on the land of the Arrohateck, and in 1613 displaced the Appamattuck to ocupy Bermuda Hundred.
The first colonial development at the current site of Petersburg was the creation of Fort Henry in 1645, after the 1644 uprising led by the paramount chief and brother of Powhatan, Opechancanough. The frontier fort served as a trading post with Native American tribes to the southwest. After Abraham Wood's son-in-law, Peter Jones, took over the business, the site was named after him.

George Washington recognized that Petersburg's location at the confluence of the Appomattox and James rivers was advantageous, but the city would have to compete with Richmond and Hampton Roads. The James River and Kanawha Canal would redirect central Virginia trade to Richmond, while the Dismal Swamp Canal would redirect Roanoke River trade to Portsmouth/Norfolk.
