Explanation:

Florida or Spanish Florida as it was known, was the first territory claimed by a European power in North America.

It was much larger than the present state of Florida and included parts of present day Georgia, Alabama, Mississippi, North Carolina and South Carolina.

Established by Juan Ponce de León for the Spanish crown, Spain found it particularly difficult as well as too unattractive to maintain a significant presence which led to the territory continually shrinking until it's authority in Florida barely extended out of the various ports that were established.
