Republic of West Florida
This flag flew over the Free and Independent State of West Florida from September 23 to December 6, 1810. This state covered the area below the thirty-first parallel between the Mississippi and Pearl Rivers--now a part of Louisiana. The flag later became the unofficial ensign of the South in 1860-61 and inspired Harry McCarthy to compose the well-known song, "The Bonnie Blue Flag."
This area was not part of the original Louisiana Purchase nor part of Louisiana when it became a state. However, as its first legislative act, West Florida was annexed and became part of the state of Louisiana in 1812.
The "Florida Parishes" as they are called today include: East Baton Rouge, East and West Feliciana, Livingston, St. Helena, St. Tammany, Washington, and Tangipahoa.
