The man--as his mature prose testifies--was of nervous temperament, and was led into one political scrape after another. At the very beginning of his career, carried away by the propaganda of Benjamin Constant, he committed an act of indiscipline against the Minister of War which has become famous in the annals of Brazilian politics, having required the benevolent intervention of the Emperor. His journalistic labours began in 1888; the following year found him at the Escola Polytechnica of Rio de Janeiro, finishing his course as an engineer, but the proclamation of the Republic interrupted his studies and he returned to the army. The material for his famous book was gathered while in the service of the important newspaper _Estado de São Paulo_, for which he went into the wilds to report the government campaign against the fractious inhabitants of the sertão. The campaign, as taught in the Brazilian schools, marked another stage in the establishment, the consolidation, of the Brazilian republic. It took place during the presidency of Prudente de Moraes (1894-1898) and brought within the folds of the new régime the rebellious sertanejos, who had rallied round the leadership of Antonio Vicente Mendes Maciel. Maciel was born circa 1835 in Ceará and had, since 1864, attracted attention because of his strange religious notions, his queer garb, his legendary personality. Accused of crime, he was vindicated and went off toward the interior of Bahia, wandering in every direction over the sertões and reaching, at last, a tiny hamlet of Itapicuru, which he christened with the name Bom Jesus (Good Jesus) on November 10, 1886. The Archbishop of Bahia objecting, Maciel was ousted in 1887 as a preacher of subversive doctrines. His followers accompanied him, however, to Canudos, an old cattle ranch which, in 1890 was an abandoned site with some fifty ramshackle ruins of cottages. Thither came flocking an army of devotees and riff-raff, so that, when Maciel resisted the government that was intent upon collecting its taxes, he had a respectable number to heed his cry of insurrection.
