###Input: During Reconstruction and the Gilded Age, Jacksonville and nearby St. Augustine became popular winter resorts for the rich and famous. Visitors arrived by steamboat and later by railroad. President Grover Cleveland attended the Sub-Tropical Exposition in the city on February 22, 1888 during his trip to Florida. This highlighted the visibility of the state as a worthy place for tourism. The city's tourism, however, was dealt major blows in the late 19th century by yellow fever outbreaks. In addition, extension of the Florida East Coast Railway further south drew visitors to other areas. From 1893 to 1938 Jacksonville was the site of the Florida Old Confederate Soldiers and Sailors Home with a nearby cemetery.

On May 3, 1901, downtown Jacksonville was ravaged by a fire that started as a kitchen fire. Spanish moss at a nearby mattress factory was quickly engulfed in flames and enabling the fire to spread rapidly. In just eight hours, it swept through 146 city blocks, destroyed over 2,000 buildings, left about 10,000 homeless and killed 7 residents. The Confederate Monument in Hemming Park was one of the only landmarks to survive the fire. Governor Jennings declare martial law and sent the state militia to maintain order. On May 17 municipal authority resumed in Jacksonville. It is said the glow from the flames could be seen in Savannah, Georgia, and the smoke plumes seen in Raleigh, North Carolina. Known as the "Great Fire of 1901", it was one of the worst disasters in Florida history and the largest urban fire in the southeastern United States. Architect Henry John Klutho was a primary figure in the reconstruction of the city. The first multi-story structure built by Klutho was the Dyal-Upchurch Building in 1902. The St. James Building, built on the previous site of the St. James Hotel that burned down, was built in 1912 as Klutho's crowning achievement.

In the 1910s, New York–based filmmakers were attracted to Jacksonville's warm climate, exotic locations, excellent rail access, and cheap labor. Over the course of the decade, more than 30 silent film studios were established, earning Jacksonville the title of "Winter Film Capital of the World". However, the emergence of Hollywood as a major film production center ended the city's film industry. One converted movie studio site, Norman Studios, remains in Arlington; It has been converted to the Jacksonville Silent Film Museum at Norman Studios.

Jacksonville, like most large cities in the United States, suffered from negative effects of rapid urban sprawl after World War II. The construction of highways led residents to move to newer housing in the suburbs. After World War II, the government of the city of Jacksonville began to increase spending to fund new public building projects in the boom that occurred after the war. Mayor W. Haydon Burns' Jacksonville Story resulted in the construction of a new city hall, civic auditorium, public library and other projects that created a dynamic sense of civic pride. However, the development of suburbs and a subsequent wave of middle class "white flight" left Jacksonville with a much poorer population than before. The city's most populous ethnic group, non-Hispanic white, declined from 75.8% in 1970 to 55.1% by 2010.

Much of the city's tax base dissipated, leading to problems with funding education, sanitation, and traffic control within the city limits. In addition, residents in unincorporated suburbs had difficulty obtaining municipal services, such as sewage and building code enforcement. In 1958, a study recommended that the city of Jacksonville begin annexing outlying communities in order to create the needed tax base to improve services throughout the county. Voters outside the city limits rejected annexation plans in six referendums between 1960 and 1965.
