In December 1931 the syndicates were dealt a blow by the failure of the Caisse centrale de Crédit agricole (Central Bank of Agricultural Credit). In the confusion that followed Le Roy Ladurie was made secretary-treasurer of the
Union centrale des syndicats agricoles (UCSA, Central Union of Agricultural Syndicates). He managed to arrange support from the
Banque Worms through his brother
Gabriel. In 1934 he became secretary-general of the UCSA, which was renamed the
Union nationale des syndicats agricoles (UNSA, National Union of Agricultural Syndicates). Le Roy Ladurie was the General Secretary of the
Front paysan that supported
Henry Dorgères and his quasi-
fascist Greenshirts in 1933–35. He published an article that violently attacked the government for lowering production targets at a time when there were 300,000 foreigners in France, many working "stolen" French soil and refusing to be assimilated. Le Roy Ladurie addressed 8,000–10,000 participants at the first annual conference of the Greenshirts on 11 December 1935 in
Bannalec, Finistère. Later he drew away from the Greenshirts. Where Dorgères was against the government's policy of employer-paid social welfare for peasant families, and wanted a welfare regime fully subsidized by the state, Le Roy Ladurie saw the weakness of the government plan as an opportunity for the UNSA to take over peasant welfare using a tax on the purchase of agricultural products. Dorgères was not invited to the
Peasant Congress at Caen on 5–7 May 1937 where Le Roy Ladurie, influenced by Rémy Goussault and
Louis Salleron, invited the leading conservative agrarians to declare their support for
corporatism. The weekly
Syndicats paysans, co-edited by Salleron and Le Roy Ladurie, first appeared on 1 July 1937. Le Roy Ladurie had great energy and was a brilliant orator. He was anti-republican and a convinced corporatist. He believed that peasants should be aware of their strength, united and organized to avoid the malign interference of the republican state. By 1938 the UNSA was the largest national peasant organization, with many of its members young and technically skilled. In June 1938 Le Roy Ladurie and his ally Alain de Chantérac were arrested for leading a peasant rally in
Castres. However, he mostly devoted his energy to strengthening local corporatist agricultural groups, which would progressively supplant the state in managing the agricultural economy, but avoid direct confrontation. He was politically very conservative, and a strong supporter of the
Munich Agreement of September 1938. ==World War II (1939–1945)==
