Adrien Albert Marie, Comte de Mun (French pronunciation: [adʁjɛ̃ albɛʁ maʁi kɔ̃t də mœ̃], 28 February 1841 – 6 October 1914), was a French political figure and Social Reformer of the nineteenth century.
Albert was born at Lumigny-Nesles-Ormeaux, Seine-et-Marne. He entered the French Army, saw much service in Algeria (1862), and took part in the fighting around Metz in 1870 (during the Franco-Prussian War). On the surrender of Metz, he was sent as a prisoner of war to Aachen (Aix-la-Chapelle), where he met René de La Tour du Pin. They both were determined to respond to the dilemma of the working class upon their release from prison. The following year they organized a Catholic Workers’ club, under the name “L’Oeuvre des Cercles Catholiques d’Ouvriers” (Society of Catholic Worker Circles), at the request of Maurice Maignen (founder of the Brothers of St. Vincent de Paul). The clubs spread quickly throughout France. These “circles” or clubs brought together the wealthy and the workers from a given locale for prayer, socializing, and hearing lectures by members of the aristocracy. He also assisted in the capture of Paris from the Paris Commune.
A fervent Roman Catholic, Albert devoted himself to advocating Social Catholicism. His attacks on Third French Republic's social policy ultimately provoked a prohibition from the Minister of War. He thereupon resigned his commission (November 1875), and in the following February stood as Royalist and Catholic candidate for Pontivy. The influence of the Church was exerted to secure his election, and, during the proceedings, he was awarded the Order of Saint Gregory the Great by Pope Pius IX. He won the next elections for the same area, but the result was declared invalid. De Mun was re-elected, however, in the following August, and for many years was the most conspicuous leader of the anti-Republican party. "We form", he said on one occasion, "the irreconcilable Counter-Revolution".
