AHC: Nationalist Brazil in the 1910s

Brazil was one of the most powerful and well off nations in the Americas when it was an empire, nearly as powerful as the United States of America itself at some points. Then the emperor was overthrown and the republic was proclaimed. During the republic, corruption was widespread, the government was rather inefficient and the military was way too powerful until it too was overthrown in a coup and replaced by a dictatorship. Would it be possible for a nationalist takeover of Brazil in the 1910s, when Europe was rather nationalistic and Brazil was in one of its low points? If so, how would this happen? Military coup? Legitimate elections? Revolution?

Integralism was a nationalist movement in the 1930s. It was essentially a non-racist form of fascism, which makes it very unique. However, this is about two decades after what I'm looking for. Were there ever any movements to restore the Empire or anything like that during the republic?

Depending on how you look at it- Getulio Vargas put together a rather nationalistic regime. There was a Constitutionalist coup in 1932 and a fascist coup attempt in 1938 that could have swung Brazil in a more radically socialist or fascist vein.

Brazil managed to get a major boost when Argentina committed economic suicide with Peronism completely buggering any useful industrialization plan or development of a robust commercial banking system that could fund industrial development.
Brazil has infinite potential between the human and physical resources to be a first world nation. It's actually #6 economy in the world now despite the rough start in the 20th century.

IMO a nationalist Brazil in 1910 wouldn't have helped. Brazil's economy needed to change from the coffee barons who wanted serfs to work the plantations to an industrial and commercial economy with an educated middle class that they have now.
It wasn't nice or easy but a relative beacon of progress compared to the nightmare Colombia's gone through.

As a norteamericano, I think a better relationship between the US and Brazil would've accelerated that process, but the US'd have to quit patronizing Brazil and Brazil'd have to liberalize quicker.
It would've benefited both countries economically with a free trade agreement, lots of co-development between American and Brazilian universities and corporations, and so forth.

YMMDV but you posed an interesting WI deserving a response.
