Brunswick County, North Carolina: History
The county was formed in 1764 from parts of Bladen County and New Hanover County. It was named for the colonial port of Brunswick Town, which itself was named for George I, the King of England and Duke of Brunswick.
Following the destruction of Brunswick Town during the American Revolutionary War, the southern portion of the county increased in population, with the town of Smithville being incorporated in 1805. Three years later it was designated the county seat. During the antebellum era, Brunswick experienced some growth. The slave labor force increased to serve plantations in their production of naval stores, corn, cotton, and rice; by 1860 over 44 percent of the county's population were slaves. During the American Civil War, forces of the Confederate State of America erected Fort Anderson near the ruins of Brunswick Town to defend against federal attacks on the Cape Fear River and the Port of Wilmington. Brunswick County did not experience much growth in the latter half of the 19th century. Smithville was renamed Southport in 1887. Beginning in the 1930s, development along the county's beaches occurred, and between 1955 and 1975, six communities on the county's barrier islands were incorporated.
