In September 1909, as usual, the young members of Rio de Janeiro's institutions of higher education celebrated the start of spring. Students in many Latin American capitals used to take to the streets to celebrate the new season. But on September 22 of that year, the street party gave way to a figurative funeral procession for Commander Souza Aguiar.
The protest represented the political burial of the general, following the expression common at the time, "morrer por ridículo" ("to die of ridicule"). Through the streets of Centro, the students carried a coffin with the phrase "Morreu o general Souza Aguiar" ("General Souza Aguiar has died"). The provocation was a response to the violence with which the commander general of the Federal District's Força Policial had reacted to the preceding demonstrations, especially the one from the previous day, in which the students tried to stop a Força Policial vehicle.

The procession continued to the Largo de São Francisco de Paula, where it was ambushed and attacked by plainclothes individuals linked to the police. Two students were killed, and several others wounded on the steps of the Escola Politécnica, which caused an uproar among part of the Rio de Janeiro population. In the aftermath of the case, a divide formed. On one side were the civilians, the students, and their supporters; on the other, the military and sympathizers of the legalist force.

The Brazilian political context in 1909 was marked by the power struggle between militarists and civilists, represented, respectively, by Marshal Hermes da Fonseca and Rui Barbosa, candidates in the 1910 presidential elections. The tension between the two groups reverberated throughout the electoral campaign, even after the sentencing of the military officers accused of the students' deaths.

The trial was marked by intimidation of jurors and witnesses by the Army, and ended with the conviction of the defendants, among them Souza Aguiar's nephew, João Aurélio Lins Wanderley.
