He married Marguerite Cerruti in September 1926, but the couple divorced in 1928.
In 1930, he was the sous préfet of Châteaulin. During that time, he also drew political cartoons in the newspaper Le Rire, under the pseudonym Romanin. He also became an illustrator for the poet Tristan Corbière's books, among others he made an etching for La Pastorale de Conlie, a book about the camp of Conlie where many Breton soldiers died in 1870. He also made friends with the Breton poets Saint-Pol-Roux in Camaret and Max Jacob in Quimper.
He became France's youngest préfet in the Aveyron département, in the commune of Rodez, in January 1937.
During the Spanish Civil War, some believe he supplied arms from the Soviet Union to Spain. A more commonly accepted version of events is that he supplied French planes to the anti-fascist forces from his place within the Aviation Ministry.
In November 1940, the Vichy government ordered all préfets to dismiss left-wing elected mayors of towns and villages. When Moulin refused, he was himself removed from office. He then lived in Saint-Andiol (Bouches-du-Rhône), and joined the resistance. Moulin reached London in September 1941 under the name Joseph Jean Mercier, and met General Charles de Gaulle, who asked him to unify the various resistance groups. On January 1, 1942, he parachuted into the Alpilles. Under the codenames Rex and Max, he met with the leaders of the resistance groups:
In his work in the resistance, he was assisted by his private administrative assistant Laure Diebold.
In February 1943, Moulin went back to London, accompanied by Charles Delestraint, head of the new armée secrète group. He left on March 21, 1943 with orders to form the Conseil National de la Résistance (CNR), a difficult task since each resistance movement wanted to keep its independence. The first meeting of the CNR took place in Paris on May 27, 1943.
Jean Moulin was arrested June 21, 1943 in Caluire-et-Cuire (Rhône), a suburb of Lyon, in the home of Doctor Frédéric Dugoujon, where a meeting with most of the resistance leaders was taking place. Interrogated in Lyon by Klaus Barbie, head of the Gestapo there, and later in Paris, he never revealed anything to his captors. He eventually died near Metz, probably due to injuries suffered either during the torture itself or in a suicide attempt, as Barbie alleged. Moulin's biographer, Patrick Marnham, supports the latter explanation, though it is widely believed that Barbie personally beat Moulin to death .
Two trials were unable to determine that René Hardy was a traitor, and both concluded that he was innocent.
A recent TV film about the life and death of Jean Moulin depicted René Hardy collaborating with the Gestapo, thus reviving the controversy. The Hardy family attempted to bring a lawsuit against the producers of the movie.
There have been many allegations of Communism in the post war years, because some of Moulin's friends were Communists. While these allegations continue, no hard evidence has ever backed up this claim. As préfet, Moulin even ordered the repression of Communist 'agitators' and went so far as to have police keep some under surveillance (Marnham's The Death of Jean Moulin, Biography of a Ghost, p104).
Marnham looked into the allegations that Moulin was likely to have been a Communist but at each turn finds no evidence to support the accusation (though members of the party could easily have seen him as a 'fellow traveler' due to his Communist friends and support for the anti-fascist forces in Spain).
It has also been suggested, principally in Marnham's biography, that Moulin was betrayed by Communists. Marnham specifically points the finger at Raymond Aubrac and possibly at his wife, Lucie Aubrac. He makes the case that Communists did at times betray non-Communists to the Gestapo and that Aubrac has been linked to harsh actions during the purge of collaborators after the war. However, Marnham does not provide evidence to support his theory, a fact which does little to distinguish it from many other theories on this subject.
To counteract the number of baseless (if not downright fictional) accusations leveled at Moulin, his personal secretary during the war, Daniel Cordier, has written an ambitious biography of his former patron. In what has been termed 'The Cordier Revolution', he has insisted on basing his research on paperwork and other verifiable evidence rather than allow Resistance history to become, as Napoleon might have termed it, 'a set of lies agreed upon'. This decision has also been controversial in that it is sometimes seen as denying the living Resistants the right to be the main witnesses to their own history, instead allowing that history to speak for itself.
Moulin was initially buried in Le Père Lachaise Cemetery in Paris. His ashes were later transferred to The Panthéon on December 19 1964. The speech given by André Malraux, writer and minister of the Republic, upon the transfer of his ashes is one of the most famous speeches in French history.
Today, Jean Moulin is used in French education to illustrate civic virtues, moral rectitude and patriotism. He is a symbol of the Resistance. Many schools and a university (Lyon III), as well as innumerable streets and squares, have been named after him, and the Musée Jean Moulin commemorates his life and the Resistance.
