Mary I's "Carta de Lei" (law) of 1787 replaced the "Real Mesa Censória" with the "Mesa da Comissão Geral sobre o Exame e Censura dos Livros" (Board of the General Commission on the Exam and Censorship of the Books), the Queen having asked Pope Pius VI to provide this organ with the adequate jurisdiction for the censorship works throughout the entire Portuguese Empire. On December 17, 1793 Portugal returned to a system similar to the one in use before the Real Mesa Censória, with the separation of duties between 3 authorities: Pontifical, Royal and Episcopal. This meant that the Inquisition once again set foot on Portuguese lands. These were, however, times of change. Some periodicals, like the "Correio Brasiliense" (1808), the "Investigador Português" (1811), and the "Campeão Português", managed to evade investigation during this period. During the Peninsular war, a rigorous regime of censorship was instituted by the French authorities, similar to the one in place in France at the time. Despite that, clandestine newspapers were still published. It would be from London, however, that the political refugees, with the support of local Portuguese merchants, would start an abundant literary production and an effort to translate the most important liberal works by John Locke, Adam Smith and Benjamin Franklin, among others, and establish dozens of periodicals, some of them being printed until after the Civil War.
