After the second restoration of the Bourbon dynasty (1816), Canosa was appointed Minister of Police. Canosa was determined to root out any revolutionary threat by purging the justice system, the army, the civil service and the educational system of all those who had compromised themselves with Murat's government. He endeavoured to unleash a massive repression against the
Carbonari and
Freemasons, and proposed to arm and support the
Calderari, a secret society formed early in the century in opposition to the Carbonari. However, his extreme political views made him highly suspect to Metternich who insisted on his removal from Naples. In June 1816, Canosa was forced to resign and banished from the kingdom by his rival
Luigi de' Medici, while some of his followers were arrested and tried. He regained the office in 1821, but was quickly dismissed at
Metternich's insistence, and the king urged him to leave the country. Canosa thenceforth devoted himself to the fight in defense of the kings and against
atheism and subversion. He wrote several pamphlets, books and articles against
liberalism and collaborated with politically explicit and combative newspapers, such as
La Voce della Verità (The Voice of Truth). For his reactionary ideas, he was expelled from Tuscany (1830), and he settled in the
Duchy of Modena, where the reigning Duke,
Francis IV, appointed him his advisor. He began a propaganda campaign in favor of legitimism and against liberalism and established royalist
militias, the Battalions of Volontari Estensi, tasked with “maintaining order in the countryside by seconding the active troops in case of need”. In 1835 he moved to the
Papal States, where he was employed by Cardinal
Tommaso Bernetti to form another counter-revolutionary militia known as the Centurioni. Canosa died in
Pesaro on 4 March 1838. == Works ==
