British Florida after the French and Indian War.
Florida is a region located in the Province of Georgia in the Southern Confederation. It originated as a Spanish colony, and became British territory after the French and Indian War. During that time period, it was divided into two colonies known as West Florida and East Florida. At some point during or shorty after the North American Rebellion, it returned to Spanish hands. Sobel does not state how this happened. It is possible that the British government might have sold Florida back to Spain to cover the costs of the Rebellion, but this is just speculation.
However Spain regained Florida, its possession proved short-lived. Throughout the early 1790s, Georgians had invaded Spanish Florida regularly in search of marauding Seminoles, whom the Spaniards were either unable or unwilling to control. The government of King Charles IV issued regular protests, and in 1794 even went so far as to send Spanish troops into Georgia in retaliation. When word of the outbreak of the Trans-Oceanic War reached the Southern Confederation, the government of Georgia promptly sent an army into Florida under the command of Colonel Richard Tomkinson. Colonel Tomkinson's men crushed the Spaniards and massacred the Seminoles, and within a year Florida was under Georgian control. The Georgians annexed Florida without consulting either S.C. Governor John Connolly, Viceroy Sir John Dickinson or the British Parliament. The Georgian annexation of Florida was retroactively confirmed by Parliament, which made Georgia the largest and most powerful province in the Southern Confederation.
The Georgia coast where Ezra Gallivan spent his annual "fishing fortnight" with Christopher Hemingway almost certainly referred to the Florida region. After the Mexican conquest of New Granada in 1890, thousands of New Granadan refugees settled in the Florida city of Tampa. However, Gallivan refused to allow the refugees to establish a government-in-exile, fearing that the Mexican government would find such a move provocative.
