Gauthier de Clagny ran for election as a Deputy for the second district of Versailles in the national legislature on 22 September 1889 on the Parti National platform, and was elected on the first ballot. Gauthier de Clancy was respected for his legal expertise. He supported the Bonapartist and Nationalist causes. He was appointed to many committees and often spoke in the Chamber. He was against the tax on rent and in favor of protecting French labourers from foreign competition. He was reelected on the first ballot on 20 August 1893 and on 8 May 1898. In 1897 Gauthier de Clagny became vice-president of the
Ligue des Patriotes. He watched the evolution of the
Dreyfus affair closely, and was indignant at the passivity of the government, particularly
Jean-Baptiste Billot. The admissions by Colonel
Hubert-Joseph Henry and his suicide were devastating to him. On 2 September 1898 he told a writer for
Le Jour that "this completely changes things." After this he stayed silent and was no longer involved in the agitation. On 27 April 1902 Gauthier de Clagny was reelected in the first round on the platform of the Républicaine Démocratique - Fédération Révisionniste alliance.
Gabriel Syveton, treasurer of the
Ligue de la patrie française, was elected deputy for the Seine in this election. In the Chamber of Deputies Syveton was appointed secretary of the nationalist and republican group. Others in the group were
Godefroy Cavaignac and Gauthier de Clagny. Most of the League's activists abandoned the League in favor of Gauthier de Clagny's Républicains plébiscitaires or
Jules Méline's Fédération républicaine. Gauthier de Clagny was elected once more on 6 May 1906 in the first round. The draft law of 13 July 1906 that reinstated Dreyfus in the army was adopted without debate. Gauthier de Clagny was among the anti-Dreyfusards who abstained. After his term expired on 31 May 1910 he did not run for reelection. He died on 16 December 1927 in Paris. ==Publications==
