1. Economic Development in Occoquan and its Dependence on Enslaved Peoples Marker
As colonial settlements moved inland during the 1600s, many colonists were looking to expand the production and shipment of crops, timber products, and pig iron.
While the Occoquan River's shallow depths limited commercial shipping, its location among the Virginia Fall Line and the natural resources available along its banks led to its role as an early location of industrial development.
Initial endeavors included copper mining along the Occoquan River; however, the region's primary industrial ventures began when John Tayloe founded an ironworks on Neabsco Creek in 1737. John Ballendine later established the Occoquan Forge in the 1750s on the south bank of the Occoquan River with financing from the Tayloe family. The two operations worked in tandem to produce pig iron.
Operating the ironworks took an immense amount of labor. Enslaved people were known in Tayloe family business to work on wood cutting and coal burning and served as founders, fillers, miners, and other laborers. Many of the enslaved workers at Neabsco and Occoquan were highly skilled. They formed most of the labor force responsible for the profitability of the Tayloe family's operations, until iron production ceased by approximately 1800.
After the ironworks' closures, Neabsco and Occoquan's early 19th-century economies centered on milling, cooperage, quality services and trades (blacksmithing, carpentry, shipbuilding, spinning , and weaving), hospitality, and transportation, though these areas still relied heavily on enslaved people.
" slave labor served as the lubricant in the machine of entrepreneurship. The presence of large populations of enslaved African Americans enabled the Tayloes and other planters to branch out from staple agriculture and ultimately necessitated that they continued to do so. Slaves demonstrated their abilities, became central to the daily operations of the South's business culture, and made the enterprises planters founded profitable."

As detailed by Laura Croghan Kamoie in Neabsco and Occoquan: The Tayloe Family Iron Plantations, 1730-1830 (pg. 20), the painting above shows a furnace complex in operation though the furnace is only one component of an ironmaking facility. Natural resources were charged into the top of the stack from the structures above it, power was provided by water-driven mills, and sheds at the bottom provided shelter for the pig iron.
