The League for the Recovery of Public Morality is a French federation of local associations working for the respect of what it considered "good morals". Created in 1883, by Tommy Fallot, the league supports the abolition of prostitution and is opposed to pornography, alcohol and gambling. Initially the league opposed alcohol and pornography, but after Fallot met with English anto-prostitution activist Josephine Butler, the end of prostitution was added to its aims. It initiated many actions against films before self-dissolving in 1946. The league published a monthly magazine, The Social Recovery, from 1893. In 1946, it succeeded La Rénovation, and reformed as the Cartel d'action sociale et morale.
In terms of prostitution, the league particularly opposed the Société de protestation contre la licence des rues, led by the "Father modesty", René Bérenger, who wanted to deregulate prostitution and brothels. The fight against "pornography" covers a broad spectrum; it tries to convince the railway companies to repaint the walls of the toilets more often in order to erase obscene graffiti. Émile Pourésy and the league often oppose La Vie Parisienne. Although formed mostly of bourgeois, the league is difficult to classify on a political level. E. Pourésy addresses the Action Française League, by invitation, who see him as a defender of neo-Malthusianism. At the third congress of the movement, in 1905, the philosophy professor Edmond Goblot accused the bourgeoisie as being the cause of prostitution.
The LRMP had a very active local branch in Lyon. The branch protested the presence of swimmers near the Quai Saint-Vincent and the showing of the 1923 filmLa Garçonne. This prompts a police investigation of mayor Édouard Herriot, which concludes there has been no wrongdoings.. The local did however obtain the prohibition in 1933 of La Marcheau Soleil, a film about the nudism in France. In 1936, it mounted a campaign, along with members of the La Cagoule, against Abel Gance's film, Lucrezia Borgia. The film was banned by Georges Cohendy, the president of the special delegation of Lyon under Vichy in November 1940.
In 1946, the League was re-formed as Le Cartel d'action sociale et morale. It was directed by Daniel Parker, who sued to Boris Vian over the novel I Spit on Your Graves. Among its members were Maurice Leenhardt, professor at the École pratique des hautes études; Canon Viollet ; physician Édouard Rist; André Mignot, deputy leader of the MRP and mayor of Versailles and Charles Richard-Molard, General Delegate of the Cartel. The Loi Marthe Richard, which led to the closing of brothels, was proposed by MRP deputy Pierre Dominjon, a member of the Cartel. Dominjon also pushed through the vote of the law of July 16, 1949 on publications intended for the youth. Daniel Parker was sidelined after Gaston Gallimard discovered, by use of a private detective, his taste for underage boys; he was succeeded by Andre Mignot.
