Originating in the Republic of West Florida in the early 1800's, the Bonnie Blue Flag was the unofficial first flag of the Confederacy.

The first recorded use of the lone star flag dates to 1810. On September 11 1810 a troop of West Florida dragoons set out for the provincial capitol at Baton Rouge under this flag. They were joined by other republican forces and captured Baton Rouge, imprisoned the Governor and on September 23 1810 raised their Bonnie Blue flag over the Fort of Baton Rouge. Three days later the president of the West Florida Convention, signed a Declaration of Independence and the flag became the emblem of a new Republic. By 10 December, the flag of the United States replaced the Bonnie Blue after President Madison issued a proclamation declaring West Florida under the jurisdiction of the Governor of the Louisiana Territory. With this rebellion in mind, this flag was used by the Republic of Texas from 1836 to 1839.
