Quality unisex cotton Onesies. The Bonnie Blue is also known as the “Lone Star Flag”, and first flew over the Republic of West Florida 1810. This republic was formed by the English speaking people of southern Alabama, Mississippi, and portions of Louisiana who rebelled against the reign of Spanish government and overthrew Spain’s provincial Governor in Baton Rouge. It reappeared in 1839 with Texas’ independence from Mexico, when the Republic of Texas adopted a variation of the Lone Star for its official flag. At the outbreak of the War Between the States, the Bonnie Blue became the flag of Mississippi after it seceded from the Union. It was immortalized by a song of the same name, and next to Dixie, perhaps no other song was more popular with the Confederate soldier. The Bonnie Blue Flag became the first unofficial flag of the Secessionist movement of the Southern States.
