Big problem with having a bloodier 1930 is the Army(the institution which mattered for this) didn't really want to fight - when the military heads saw the lower officers(from Major downwards) wouldn't obey orders to make a stand, the calculus became that deposing Washington Luís would give a...
Yes, she would be divisive. My opinion is she would be seen more like Marta Suplicy was after her term than Olívio Dutra, though. Agree she would push for similar things Dutra did, but while I can't comment on Dutra's competence in any way, her short term as acting-governor(replacing Garotinho...
Bernardo Pereira de Vasconcelos was a liberal in the first half of the 1830s, though('Fui liberal...", as he himself said). The problem would be choosing someone who would already be a conservative back in 1831, while not being someone who wanted to bring Pedro I back. Perhaps the Duke of...
In theory, the only mass transit he could do something about was the metro, because the Rio de Janeiro Metro was owned by the Rio de Janeiro State(as it had begun not as the Rio de Janeiro City Metro, but as the Guanabara State Metro - The Rio Metro is a State, not a Municipal concession, even...
Don't know enough to comment on Campinas, but I can say that, no matter whether Campinas Light Rail succeeds or fails, Rio de Janeiro would probably not adopt it in the early 90s; Rio de Janeiro City was short on money back then and the favoured transport mode would have probably been Bus Rapid...
The Integralists had even less chance of getting into power than the Federalists did in 1893. The fact that his father renounced the right for the throne(and honored that act while he lived) wouldn't quite count if the Integralists really wanted to put an Emperor on the throne.
Had forgotten...
Best bet for me is either D.Pedro II choosing to resist the coup(but his personality makes that improbable at best), or D.Isabel heeding Gaspar Silveira Martins' proposal to get her heir to Brazil during the Navy/Federalist Revolt(but that would need better military and political leadership on...
Not just that one(although it is a great example). In the late 1880s, the Brazilian Navy started to design a class of four monitors for use in the Paraguay River. Due to a debate about the the number of shafts and rudders needed to give the ships the needed maneuverability, keel-laying for the...
There were sectors of the military against joining the Korean War as well(also, it wasn't unanimity in the 'right wing'; it was something pushed by the sectors of it that felt closer to the USA). And regarding Costa e Silva, he wasn't the one who pushed for joining the Dominican Republic OAS...
Caveat: I'm not very knowledgeable on regional politics of the time, so I might be overvaluing some and undervaluing others here.
Osvaldo Aranha is the biggest name here. Bernardes... it would have been 24 years since he was president, people may give him a pass(but I wouldn't bet on him too...
