da Fonseca was one of Brazil’s leading military leaders and led the revolt that toppled Emperor Pedro II. He first served as the country’s provisional president until 1891 when he was elected to the position. 

Although he was politically conservative and personally loyal to the emperor, he felt that it was his duty as an officer to protest the despotic acts of the government and insist that his fellow officers had a right to express their political views. Declared insubordinate by Pedro II, Fonseca headed the military revolt of Nov. 15, 1889, which established Brazil as a republic. He served as provisional president until February 1891, when he was elected president by the constituent assembly, a body largely controlled by the generals. As president, Fonseca was both arbitrary and ineffective. When he attempted to rule by decree, he was forced to resign in November 1891.
