The Chaos TL by
Max Sinister - Brazil aka Braseal changes owners several times early in its colonial history (England/Sweden), but then becomes a part of the
New Roman Empire, which uses the place as a penal colony from people from Europe, Africa, India and Atlantis (the Americas). Later given independence, has to fight a civil war about the question of slavery. Even later their whole royal family gets killed in a terrorist Socialist attack, after which the German technocracy installs a new “integralist” junta. Speaks a creole of too many languages to mention, but with a strong French tendency.
