The state of Florida comprises 67 counties. In 1821, Florida became a US territory and comprised just two counties – Escambia, which was located in the west, and St Johns in the east. These two counties were divided by Suwannee River. The other counties in the state were later created out of these two original counties. In 1845, Florida joined the United States of America as its 27th state. Gilchrist County, which was created in 1925, is the youngest county of the state. It was created from a segment of the Alachua County.
