American Civil War and Emancipation
In the two decades leading up to the American Civil War, cotton was the primary source of income in the county, with about seventeen percent of all Florida cotton being grown in Jefferson County. It was also the county with the second most large plantations (fifty-five plantations with thirty or more slaves) in Florida, behind only Leon County. In 1860, the county had a population of 9,876 with sixty-four percent being black. Following emancipation, the black population of Jefferson County continued to grow. By 1870 the population had risen to 13,968 with seventy-two percent black. To serve the relatively large black population in the county, the Freedmen's Bureau established an office in Monticello sometime around early 1866.[8]

Government and politics
Jefferson County, like most counties in the Florida Panhandle, historically voted for Democratic candidates. However, while most counties in the Panhandle started reliably voting for Republican candidates, Jefferson County has divided its support among Democratic and Republican candidates. From 2000 to 2012, while Democratic candidates for President won the county, the margin dwindled over time; in 2016, the county voted for Donald Trump, the first time that it had voted for a Republican presidential candidate since 1988. In 2020, Trump expanded his margin of victory. Jefferson County consistently backed Democratic candidates in statewide races, but in 2018, Ron DeSantis became the first Republican gubernatorial nominee to win Jefferson County since 1884.

United States presidential election results for Jefferson County, Florida[30]
Jefferson County's library is the R.J. Bailar Public Library, a member of the Wilderness Coast Public Libraries Cooperative. It is located in the building that once housed the old Jefferson High School library.[32]
I-10 (Interstate 10) is the main west-to-east interstate highway in the county, and serves as the unofficial dividing line between northern and southern Jefferson County. It contains three interchanges within the county; the first being SR 59 in Lloyd (Exit 217), the second at US 19 in Drifton (Exit 225), and the third south of Aucilla at CR 257 (Exit 233). Beyond this point I-10 runs through Madison County.
US 19 is the westernmost north-south US highway in the county. It enters from southwestern Madison County as the Georgia-Florida Parkway in a concurrency with US 27, then breaks away from US 27 in Capps to run straight north through Monticello where it encounters a traffic circle with US 90 around the historic Monticello Courthouse. North of the city it runs through the State of Georgia.
US 27 is another north-south US highway in the county. It enters from Madison County in a concurrency with US 19, but unlike US 19 breaks away at Capps and runs west toward Tallahassee.
SR 59 is the westernmost north–south highway in Jefferson County and is the only roadway connection between U.S. 90 (at its intersection in Leon County) to the southernmost east–west route through Jefferson County, U.S. Route 98.
US 90 was the main west-to-east highway in the county, until it was surpassed by I-10. It enters the county from Leon County twice, the second time from a causeway over the southern end of Lake Miccosukee, and eventually enters Monticello in a traffic circle with US 19. East of the city, it curves southeast through rural Jefferson County, then passes north of Aucilla before crossing the Madison County Line at a bridge over the Aucilla River.
US 98 is the southernmost east–west route running through the Conservation Areas of the Gulf of Mexico from Wakulla to Taylor Counties. The sole major intersection is with SR 59.
US 221 is the easternmost US highway in the county, running south and north through the northeastern portion of Jefferson County, including Ashville before crossing the Georgia State Line.
CR 259 is a west-east two-lane road known as the Waukeenah Highway in the county that runs from the Leon County line through Wacissa and terminates at US 19 south of the Monticello city limits.
