Flagler County was created in 1917 from portions of southern St. Johns County and northern Volusia County. The county was named after Henry Morrison Flagler, a railroad and oil tycoon, who was a developer of the Florida East Coast Railway during the 1880s and 1900s. Bunnell, located 30 miles south of St. Augustine, was established as the county seat. Joseph Marion Hernandez, the first Hispanic to serve in the US Congress, had three successful sugar plantations in Flagler County until they were burned down by Native Americans in 1836, during the Second Seminole War. Marine Studios, later named Marineland, opened in 1938 as the world's first underwater motion picture studio. The economic driving force in the county until the early 1970s was its agriculture and forestry industry. In the late 1960s, International Telephone and Telegraph Corporation (ITT) purchased 22,000 acres of timberland and established the retirement community of Palm Coast. Today, the county thrives upon successful real estate and service industries.
