 The uneasy truce with the Church ended with Obregón's 1924 handpicked succession of the atheist Plutarco Elías Calles.Mexican Jacobins, supported by Calles's central government, went beyond mere anticlericalism and engaged in secular antireligious campaigns to eradicate what they called "superstition" and "fanaticism," which included the desecration of religious objects as well as the persecution and the murder of members of the clergy.Calles applied the anticlerical laws stringently throughout the country and added his own anticlerical legislation.
