Spanish West Florida
The region of West Florida initially had the same borders as the erstwhile British colony. Much of its territory was gradually annexed by the United States in the West Florida controversy. At its greatest extent, the colony included what are now the Florida Parishes of Louisiana, the southernmost parts of Mississippi and Alabama, and the panhandle of Florida. Whereas southeastern Louisiana and present-day coastal Mississippi and Alabama were annexed either prior to or during the War of 1812, the land which makes up present-day Florida was not acquired until several years later. It became the Florida Territory of the United States in 1822.
Spain was the first European state to colonize the Florida peninsula, expanding northward from Cuba and establishing long-lasting settlements at St. Augustine, on the Atlantic coast, and at Pensacola and San Marcos (St. Marks), on the Gulf of Mexico coast.
Following Spain's losses to Great Britain during the Seven Years' War, Spain ceded its Florida territory to Britain in 1763. British administrators then divided the territory into two colonies: East Florida, including the Florida peninsula with the capital at St. Augustine, and West Florida, to which was appended part of the territory received from France under the 1763 peace treaty. West Florida extended from the Apalachicola River to the Mississippi River, with its capital at Pensacola.
In 1779, Spain entered the American Revolutionary War on the side of France but not the Thirteen Colonies. Bernardo de Gálvez, governor of Spanish Louisiana, led a military campaign along the Gulf coast, capturing Baton Rouge and Natchez from the British in 1779, Mobile in 1780, and Pensacola in 1781.
In the 1783 peace treaty, Great Britain returned both Florida colonies to Spanish control. Instead of administering Florida as a single province, as it had prior to 1763, New Spain preserved the British arrangement of dividing the territory between East and West Florida (Florida Oriental and Florida Occidental). When Spain acquired West Florida in 1783, the eastern British boundary was the Apalachicola River, but Spain in 1785 moved it eastward to the Suwannee River. The purpose was to transfer San Marcos and the district of Apalachee from East Florida to West Florida.

Spain never drew a clear line to separate the two Floridas, but West Florida extended easterly to include Apalachee Bay, which Spain shifted from the jurisdiction of St. Augustine to more accessible Pensacola.

On July 21, 1821 all of what had been West Florida was named Escambia County, after the Escambia River. It stretched from the Perdido River to the Suwanee River with its county seat at Pensacola.
