History
Formed in 1824 from Duval County and St. Johns County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Alachua County was created from Duval and St. Johns counties on December 29, 1824. The county lost land through the creation of several new counties: Columbia in 1832, Hillsborough in 1834, Marion in 1844, Levy in 1845, Putnam in 1849, Clay in 1858, and Bradford in 1870. It also gained territory from Columbia in 1835 and adjusted its boundary with Duval in 1844.
