Caroline County was created via 1773 Maryland General Assembly legislation from parts of Dorchester and Queen Anne’s counties. The county derives its name from Lady Caroline Eden, wife of Maryland’s last colonial governor, Robert Eden. Seven commissioners were originally appointed: Charles Dickinson, Benson Stainton, Thomas White, William Haskins, Richard Mason, Joshua Clark, and Nathaniel Potter. These men bought 4 acres (1.6 ha) of land at Pig Point (now Denton) on which to build a courthouse and jail.

Until the completion of these buildings, court was held at Melvill’s Warehouse, approximately 1.5 miles (2.4 km) north of Pig Point. Elections and other business transactions were completed there. The first commissioner meeting was held on March 15, 1774, at Melvill’s Warehouse. In 1777, court was moved to Bridgetown (now Greensboro), but in the interest of convenience, court was moved back to Melvill’s.
Disagreements arose concerning the permanent location of the county seat. The General Assembly reached a compromise in 1785 and ordered that 2 acres (0.81 ha) of land at Melvill’s Landing should be purchased for a courthouse and jail. In 1790, the county court and its belongings moved to Pig Point. The Caroline County Courthouse was completed in 1797.
Caroline County is bordered by Queen Anne’s County to the north, Talbot County to the west, Dorchester County to the south, Kent County, Delaware, to the east, and Sussex County, Delaware, to the southeast.
As of the 2010 United States Census, there were 33,066 people, 12,158 households, and 8,702 families living in the county. The median income for a household in the county was $58,799 and the median income for a family was $65,801.
