(Planning on making a graphic timeline for this. The POD is a long way back in the 1700s. Also, this was a quick thing, definitely got to clean the flag up a little more)
The official name used by Spanish, French, English overlords: "The Republic of Greater West Florida" (French: La République du Grand Ouest de la Floride|Spanish: La República del Gran Oeste de Florida). Unofficial name used by everyone in the colony: "The Republic of New Jerusalem" (German: Republik Neu-Jerusalem|French: République de nouvelle Jérusalem|Spanish: República de Nueva Jerusalén).
The Spanish and the French would exile many Protestants to North America. After actually doing successful, German Protestants (who were also being prosecuted by the French puppet government of Germany) would start to flood in.
Even the English settlers who refused to leave North America went to this colony. The Spanish would be outraged, not only at the colonists because they were actually successful, but also at France for putting their exiles there. France would agree to send"loyalists" (goons) to see that the colonists would either convert or be replaced by good Catholics. Of course, they would refuse and a massacre would begin. This would outrage the Pope who wanted to have peace. He was quickly replaced.
The English Protestants there would convince the Monarchy in Britain that if they helped they could finally get some land in North America. The Royal Navy would shortly be sent. British ships would cut off any reinforcements coming from France and Spain, while their troops and the Protestant rebels would surround the Spanish Imperial Army and destroy them. France would bail (which made them spite the French so much this would later lead to the First World War). The Spanish with almost no morale and their troops dead would surrender. The British would agree to split the autonomy of the Protestants between the Spanish, French, and themselves. Spain would lose all of Louisiana to Britain.
"Into Battle with Faith" was a song sung by the rebels in West Florida
