Parti libéral mexicain
In September 1910, Figueroa was put in charge of the publication of "Regeneración" in Los Angeles, California. The newspaper was in its fourth season as the official publication of the MLP, and its slogan was "Revolutionary Weekly". He collaborated with Ricardo Flores Magon, Lazaro Gutierrez de Lara, Antonio I. Villarreal and Enrique Flores Magon, who had been released from prison in Arizona in August. Together with Ricardo and Enrique Flores Magón, he signed the Manifesto of the Mexican Liberal Party on September 23, 1911. The document took an openly anarchocommunist stance toward the armed uprisings in Mexico at the time.
