St. Johns County was established in 1821, one of the first counties created when Florida was ceded to the United States. Today the county is part of the Jacksonville metropolitan area. The county is primarily made up of residential bedroom communities. Tourism, primarily associated with St. Augustine and the many golf courses in the area, is the chief economic industry.
St. Johns County was founded in 1821 when Florida was ceded to the United States under the Adams–Onís Treaty, which was negotiated with Spain by Secretary of State John Quincy Adams.
