Osceola County was created in 1887. On July 21, 1821, Florida was divided into two counties, named Escambia County to the west and St. John's County to the east. In 1824, the southern part of St. John's County became Mosquito County, with Enterprise as the county seat. In 1844, Brevard County was carved out from Mosquito County. When Florida became a state in 1845, Mosquito County was renamed Orange County. On May 12, 1887, Osceola was named a county, having been created from both Orange and Brevard Counties. Osceola County reached all the way down to Lake Okeechobee until 1917 when Okeechobee County was formed.
Since the late 20th century, Osceola County has experienced a significant influx of migrants from the Commonwealth of Puerto Rico, the unincorporated territory of the United States,  and in the 2000 U.S. Census Puerto Rican was the largest self-reported ancestry group. 
Osceola County is a charter county, and a subdivision within the State of Florida. Voters approved the County Charter in March 1992, and it took effect on October 1, 1992. The structure of County government under the charter does not depart dramatically from the structure of a County government outlined in the Florida Statutes.
Osceola County Government is governed by three sets of elected officials, each of which independently directs separate branches of County Government. These include: the five-member County Commission, five separate Constitutional Officers, and a number of Judicial Officers. Under State law, the County Commission is responsible for funding the budgets of all Osceola County Government, including the independently elected Constitutional Officers and Judicial Officers, as well as the Commission's own departments. Each independent officer has discretion to administer his or her own programs. The County Commission exercises oversight only over its own departments.
Osceola County has five electoral districts each represented by a commissioner. All the commissioners compose the Board of Commissioners that appoint a County Manager. There also is a Commission Auditor and County Attorney.
