Lake County is created from sections of Orange and Sumter counties in central Florida. Orange County is further downsized, along with Brevard County, as Osceola County is created in the center of the state, taking its name from the Seminole leader of the same name.
In 1824, the area to the south of St. Johns County was designated Mosquito County, with its seat at Enterprise. The county's name was changed to Orange County in 1845 when Florida became a state, and over the next 70 years several other counties were created. Seminole County was one of the last to split.
