The Republic of West Florida, officially the State of Florida, was a short-lived unrecognized republic in the western region of Spanish West Florida for just over 2+1⁄2 months during 1810. In December, 1810, the United States occupied and annexed the Republic of West Florida. The governor of Orleans Territory designated the land comprising it as the County of Feliciana. The land was added to Louisiana on August 4, 1812, following an act of Congress passed earlier that year. In 1990, the region that was previously the Republic of West Florida was officially recognized as a historical region of the U.S., the "Republic of West Florida Historic Region", commonly referred to as the Florida Parishes.
