. Indirect precedents of 1918 insurrection were the arrival of works by
Bakunin,
Kropotkin and other European libertarian writers to Brazil by the end of the 19th century together with Italian and Spanish
immigrants from Europe, to serve as cheap labor force in factories and farms of wealthy Brazilian entrepreneurs. But directly, the insurrection is the consequence of the high level of organization among the Brazilian proletariat in the first decades of the 20th century, especially in
Rio de Janeiro, at the time the capital, and in
São Paulo. In
1917, resulting from the articulation of various unions and anarchist organizations, the São Paulo industry was put at a halt, with mass participation of workers in the 1917 general strike. In parallel, the
Spanish flu outbreak had spread around in many Brazilian cities, taking thousands of lives. As a consequence of the
First World War, the high cost of living had hit mostly the poorer strata of the population, and the hunger of thousands resulted in the looting of warehouses and commerce. In Rio de Janeiro, FORJ (; Worker Federation of Rio de Janeiro) begun a great campaign against this expensive cost of living and worked towards the restructuring of several trade unions. At the same time, despite not being allowed by the police, many large worker meetings popped up, in which speakers and thinkers made speeches to hundreds or thousands of people. The strike in the Corcovado textile factory was heavily repressed by the police in May, and the collapse of the Hotel New York in July, with the death of tens of workers, rose the hostility of workers and anarchists towards government officials and business owners. Work conditions in factories, as in neighborhoods such as
Barreto,
Santo Aleixo and the city of Rio de Janeiro, were terrible, in badly-lit workplaces, full of smoke, where there were no proper bathrooms for the employees but holes on the ground. Many times,
child workers received negative paychecks because of production mistakes, and physical punishment was constant. The factories were overseen by
foremen and thugs, who suppressed any protest, rather effectively, since they lived nearby the worker settlements. Even pregnant women worked tirelessly in these poor work conditions. At the beginning of 1918, news about the success of the
Russian Revolution spread throughout Brazilian capitals. Not knowing about the character of the
Bolshevik Revolution, anarchist groups came to organize themselves with the intention of overthrow the Brazilian central government. In January 1918, the Anarchist Alliance of Rio de Janeiro was created, whose main objective is to spread libertarian thinking among workers from different sectors. On March 1, the General Workers' Union (UGT) was founded, replacing the FORJ which in August 1917 had been closed by the state repressive apparatus. Since its inception, the UGT was also the target of police repression, which reacted to rumours of an alleged general strike. Nevertheless, strikes continued through 1918. On 1 May 1918, a
state of siege was declared in the city of Rio de Janeiro, workers and anarchists organized to commemorate
International Workers' Day in union offices, in halls and even in a theatre. In June, the Germinal Anarchist Group staged a festival with plays. In August, workers from Companhia Cantareira and Viação Fluminense went on strike for better wages and an
eight-hour working day, paralyzing both the Rio – Niterói ferryboats and the tramways. Faced with the strike, the businessmen activate the state repressive apparatus that try to end the strike by force. In the face of repression, the workers reacted by making the strike take on the character of an
insurrection. In the face of police violence, a considerable number of soldiers from the 58th Hunters' Battalion entered the conflict, taking up arms alongside the workers. == Planning ==
