Count Bernard de Vésins was a French soldier, essayist, practicing Catholic and right-wing Action Française militant. He was hostile to Freemasons, Jews and socialists, whom he considered to be working together in conspiracy to undermine the traditional Catholic values of France. In the 1920s he was President of the Ligue d'Action Française during a period when the Catholic Church was disassociating itself from the movement.

Action Française is a French far-right monarchist political movement. The name was also given to a journal associated with the movement.
