No sooner was Carvalho in power than the violence of his character began to display itself in the sanguinary measures he employed to suppress the brigandage that was rife in the country and even in the capital itself. The nobility, especially, were marked out for punishment; and when public criticism began to be heard, he issued furious edicts against the calumniators of the administration. He suppressed with terrible severity a rising at Porto against a wine-company which he had established there, and began a series of attacks on the most eminent personages of the kingdom. He dismissed in disgrace the minister of the navy, Diego de Mendoza; and de la Cerda, the ambassador to France; as well as John de Braganza, the Marquis of Marialva and many others. He gave the highest positions, ecclesiastical and political, to his relatives; forced the king to sign edicts without reading them, some of which made criticism of the government high treason, and he extended their application even to the ordinances of his minister; he silenced the preachers who spoke of public disasters as punishment of God; and forbade them to publish anything without his approbation. Though he reorganized the navy, he left the army a wreck, lest the nobles might control it. There was no public press in Portugal during his administration, and the mails were distributed only once a week. He encouraged commerce and organized public works, but always to enrich himself and his family. He flung thousands into prison without even the pretence of a trial, and at his downfall in 1782 says the "Encyclopédie catholique," "out of the subterraneous dungeons there issued eight hundred of his victims, the remnants of the nine thousand who had survived their entombment; and a government order was issued declaring that none of the victims living or dead had been guilty of the crimes imputed to them." This was the man who was declared by the Philosophers of the eighteenth century to be "the illuminator of his nation."
