Florida's Gilded Age Economic Boom transformed the state from a sparsely populated frontier to a bustling hub of tourism and industry. From 1880 to 1920, the population surged as railroads expanded, connecting Florida to the rest of the nation and spurring rapid development. Key figures like Henry Flagler and Henry Plant drove growth through railroad and hotel investments. Agriculture, particularly citrus, and industries like phosphate mining and timber harvesting flourished. This period laid the foundation for Florida's modern economy, but also brought environmental challenges and social inequalities.
