In December 1902 Georges Yvetot was one of the founders of the Ligue antimilitariste, along with fellow anarchists Henri Beylie, Paraf-Javal, Albert Libertad and Émile Janvion.

[2] The founder of the AIA was the Dutch pastor Ferdinand Domela Nieuwenhuis of Amsterdam, a socialist who considered that militarism was created by the capitalist press, politicians and education.

[3] The anarchists Charles Malato, Urbain Gohier and Victor Méric were founding members of the AIA, also called the Association internationale antimilitariste des travailleurs (AIAT), in 1904.

[4] Yvetot and Miguel Almereyda (Eugène Vigo) led the French section and sat on the AIA committee.

It was agreed that the AIA was committed to a workers' revolution in the event of war, but that it was neutral on the subject of desertion.

[9] The AIA tried to revive itself in March 1908 under the leadership of Georges Durupt and Gaston Delpech, but was unable to obtain an adequate base of support.

[11][12] L'Action antimilitariste : organe mensuel de combat, the journal of the AIA, appeared in 1904 and 1905.
