Here a explanation of the brazilian warlords cliques in Red Flood, but first I must remember that this cannot happen unless you provocke it or choose in country specific routes.
They are broken on the following categories:
Separatists
*Burasiru, they can core the rest of the state of São Paulo and the rest of Paraná, they are led by local oligarchs, most specifically the japanese oligarchs. While the japanese brazilian population is just about one million, the people are so exausted and never have been included in politics before, so they don't really care about who's rulling, and burasiru allies the local oligarchs inegrating them. Expect it to be always crushed by who unifies Brazil, or even before when they try to takes the rest of São Paulo from the Emergency government.
Hetmanate of Brazil: They can unify Brazil, they are led by the progressive ukrainian minority, they can ban racism due the massive amount of racism they suffered, one of the insults used by other brazilian slavs against them was "chorni", basically "blacks", claiming they were not white slavs like the others.
The Polish Enclave can only develop itself and hope for a good annexer to come close
Rio Grande do Sul, led by local oligarchs. They have two paths, the first being the Gaúcho Traditionalism-
What is Gaucho traditionalism?
This:
The other route is Social Liberal under the son of someone you know.
Amazonas technocracy: Basically a anarchy, some are scientific teams, others are tribes, troops stuck there, etc
2nd Manaus Commune. Yes,
the second.
João Amazonas escape there after losing the civil war and makes a Hoxhaist state mixed with 1984 levels of surveillance, the dark red spot in the americas.
Filinto's Clique, led by
Filinto Müller, a member of the left wing tenentistas like Prestes or Lopez who defected to the government and led Vargas special police before being fired. Since he didn't deserted on TTL he's a officer for the left at the start, but if the warlord era begins he caves his own state on Mato Grosso, extremely brutal.
New Silesia: German colonists, they can try to cave a realm for themselves, they receive support from Prussia if they reach the coast. Their leader is a brazilian luftwaffe pilot that never left to europe on this timeline,
Egon Albrecht.
Then we got the loyalists of 1889.
The first is our boy
Cândido Rondon, stuck at Rondônia when things blew up. He's too old for a war of unification, so he deals with his troops supply and the diplomacy with other warlords before retiring and his sucessor can unify Brazil restoring the 1891 constitution, and making people follow it this time.
Punaro Bley, from Blei's clique. Bley had two options: Either he would follow the boat to the bottom of the ocean, or try to repair it before it was too late, he took the second. He seized the areas north of Rio under the government orders to restore order and caved his own clique, while keeping the pre war governors still in de jure power. He began to make courts work, and not to be a tool by the oligarch to arrest, torture and kill their enemies; he made local elections work, and not be just a ritual while the politicians were appointed; he cracked down as he could in corruption to make the system works, however he's allied to the corrupt central government, and it's up for him now to decide if he will follow them, or try to be a new Marshall Deorodo and seize power by himself, this time to garantee democracy and not to bury it.
The Emergency government: If you could take everything wrong with the old republic, and remove any surveillance, you would get them.
Then we got the new republicans, who want to build a new system.
Landry Salles, from Salles Clique. Supported every single attempt to crush the old republic, the 1922 copacabana fort riot, the 1924 civil war, the manaus commune, the 1930 revolution, got dissilussioned when Vargas became a dictator OTL. Salles seizes the center-north of Brazil and allies with every reform minded left-center-right politician he can finds and form a new democratic constitution, he wants to demolish the old republic and make a new democratic one, if he wins he steps down (since the army is not made to rule) and call free elections.
Renato Pinto Aleixo, from Aleixo's clique, otl pro Vargas military officer, he announced Vargas suicide to the VP Café Filho in 1954. During the chaos in Bahia with oligarchs militia's, left wingers and local caudillos trying to seize power, he mobilized the local army and crushed them, he proceeds to democratise and return to the army as a new governor is elected, he rejoins whoever unifies Brazil.
*drum the drums*
GOÉS MONTEIRO, from Goés clique, described by scholars as "the father of all army intervention in civilian affairs", something that is not right since our first military dictator was Deodoro in 1889, still, Goés was corrupt, he ran for the presidency in 1934 and came in third and the main thing that comes from Goés is that he does not cares, neither respects, neither accepts any positive point, of democracy, nothing, whatsoever, he makes every single local politician and industrialist declare loyalty for him and proceeds to try to unify Brazil, if he wins you can expect a Reza Pahlevi kind government, but with no official reference to democracy in any government document or in the constitution.
Finally,
Lampião. Virgulino Ferreira da Silva.
Who is Lampião? Well...
"Lampião and his band attacked farms and cities in seven different states, stealing cattle, looting villages, kidnapping, murdering, torturing, mutilating and raping. His passage caused terror and indignation on the population."
He cannot unify Brazil, he can only raid and make the like of the warlords miserable until he's eventually put down, the question is how many people he can murder and how much he can steal until this happens.
I hope you liked it.
