I want to know the answer to the following question:
Who caused the fall of the monarchy happened in Brazil?
All the background I'm provided with is that "Aided by well-known jurist Ruy Barbosa, Fonseca established federalism in Brazil by decree, but this system of government would be confirmed by every Brazilian constitution since 1891, although some of them would distort some of the federalist principles.". Is that enough to answer the question?
Answer: no
