A Florida county map is a lesson in Florida history.
One can see how Florida evolved by studying the dates of formation of its counties.
When Florida became a United States territory in 1821, there were only two counties: Escambia County to the west on the Gulf of Mexico and St. Johns County to the east on the Atlantic Ocean.
Pensacola is the principal city in Escambia County and St. Augustine is the major city in St. Johns. These old Spanish settlements are the oldest cities in America, and St. Augustine is the oldest continuously occupied city in America.
From these two parent counties, the 67 counties of today evolved. The Florida County map below is courtesy of the Florida Department of Motor Vehicles and shows the county boundaries and major highways.
County websites are at the Florida Association of Counties.
