Fausto de Aguiar Cardoso (December 22, 1864 – August 28, 1906) was a Brazilian lawyer, poet, philosopher, and politician from the state of Sergipe.

Cardoso's sons, in turn, avenged their father's death and murdered Olímpio Campos shortly after in Rio de Janeiro.

He fell out of favor with local politicians in Sergipe due to his support of republican ideals, and moved to Rio de Janeiro.

The followers of Fausto Cardoso and the Military Police took over the Government Palace, invaded the Legislative Assembly, and impeached several deputies.

The Campos brothers notified the Brazilian federal government about the illegality of the movement, which became known as "Revolt of Fausto Cardoso" or the "Tragedy of Sergipe".

[2][3] Monsignor Olímpio Campos, as Senator for Sergipe, petitioned President Rodrigues Alves to send army troops from Bahia and Pernambuco to Aracaju.

Cardoso asked for water after the shooting at a house at on the corner of Rua de Pacatuba on Praça do Palácio, a broad public plaza, and died.
