From Fort to Settlement
Orlando's founding story begins not with civic planning but with military necessity. As documented by the Florida Historical Society, the U.S. Army constructed Fort Gatlin southeast of present-day downtown Orlando around 1838, during the Second Seminole War. The fort established a permanent American military presence in Central Florida at a time when the territory had no European-American civilian population to speak of in the immediate vicinity.
The transition from military outpost to civilian settlement came within a few years. Aaron Jernigan, arriving from Camden County, Georgia, in 1843, became the area's first recorded European-American settler, and the early community took his name. Over the next three decades the settlement grew slowly, obtaining a post office by 1850 and eventually incorporating as a municipality on July 31, 1875, with a recorded population of just 29 residents, as the Florida Historical Society documents.
Key Events and People
Aaron Jernigan's 1843 arrival anchors the documented origin of civilian settlement in what is now Orlando. He came from Camden County in coastal Georgia, and the early community bearing his name clustered around the terrain southeast of the present city center, in the general vicinity of Fort Gatlin. The fort itself had been positioned to protect settlers moving into the Florida interior during the ongoing conflict with the Seminole people.
The broader administrative context shifted in 1845, when Mosquito County — the original county encompassing this part of Florida — was renamed Orange County, reflecting both the region's emerging agricultural identity and the political desire to shed an unflattering name. That renaming gave the region the identity it retains today.
National magazine articles circulating in the 1870s publicized the Central Florida interior to potential settlers along the Eastern Seaboard, and the Florida Historical Society notes that these publications attracted new arrivals who began developing citrus groves on former cotton fields. That shift from subsistence agriculture to commercial citrus production was the economic engine that transformed Jernigan from an isolated settlement into a viable incorporated town. By the time Orlando formally incorporated on July 31, 1875, the citrus economy was already beginning to reshape the landscape of Orange County.
The Name Orlando
In 1857, the settlement's name was officially changed from Jernigan to Orlando, and the origin of that name has been debated by historians since. As the Florida Historical Society reports, the most widely cited explanation attributes the name to Orlando Reeves, described as an Army sentry who was reportedly killed near Fort Gatlin during the Seminole Wars. According to this account, the location of his grave or the site of his death became a local landmark that gave the emerging community its new identity.
Britannica also records the attribution to Orlando Reeves, noting that the town was renamed in his honor. The Florida Historical Society acknowledges, however, that alternative explanations exist and that the precise origin of the name cannot be confirmed with documentary certainty. What is confirmed is the year of the change: 1857, fourteen years after Jernigan's initial settlement and eighteen years before formal incorporation.
The renaming predated the county seat designation by only months, situating 1856 and 1857 as a formative two-year period in which the settlement acquired both its permanent name and its role as the governmental center of Orange County.
County Seat and Early Growth
The designation of Orlando as the Orange County seat was itself a contested civic process. The Orange County Regional History Center documents that in late 1856, voters chose the area around Lake Eola as the seat of county government — a decision that gave the settlement a durable institutional anchor and positioned it to absorb the incoming settlers of the 1870s. Lake Eola, a sinkhole lake near the center of what would become downtown Orlando, was thus woven into the city's identity from the earliest years of its formal governance.
The population of 29 recorded at incorporation in 1875 reflects how genuinely small Orlando remained at the moment it became a legal municipality. Yet the infrastructure of a post office (established 1850), county seat status (1856), and an official name (1857) meant the settlement had acquired civic identity well before its population warranted it. The citrus boom of the late 1870s and 1880s would dramatically accelerate growth, transforming what the Florida Historical Society describes as a town of 29 into a recognized regional market center within a generation. That arc — from military fort to named settlement to county seat to incorporated city — defines the founding era whose legacy the Orange County Regional History Center, operating in a 1927 courthouse in downtown Orlando, continues to document and interpret.
