General Andrew Jackson, while fighting escaped black…
1819 CE
To stop the Seminole based in East Florida from raiding Georgia settlements and offering havens for runaway slaves, the U.S. Army has led increasingly frequent incursions into Spanish territory. This includes the 1817–1818 campaign by Andrew Jackson that will become known as the First Seminole War, after which the U.S. effectively seizes control of Northeastern Florida; albeit for purposes of lawful government and administration (in the state of Georgia); but not for the outright annexation of territory for Georgia; for additional U.S. Territory; or, for the creation of another U.S. state.
John Quincey Adams had Adams said the U.S. had to take control because Florida (along the border of Georgia and Alabama Territory) had become "a derelict open to the occupancy of every enemy, civilized or savage, of the United States, and serving no other earthly purpose than as a post of annoyance to them."
Spain asks for British intervention, but London declines to assist Spain in the negotiations.
Some of President Monroe's cabinet had demanded Jackson's immediate dismissal for invading Florida, but Adams realizes that his success has given the U.S. a favorable diplomatic position. Adams is able to negotiate very favorable terms.
