Mexican Liberal Party
In 1904, Magón fled Mexico when the courts banned the printing of his writings and he remained in the United States for the remainder of his life. Half this period was spent in prison. He resumed publication of "Regeneración" and led the "Partido Liberal Mexicano" (PLM) (Mexican Liberal Party) from abroad. In 1906, he went to California. Around this time PLM uprisings occurred in Mexico which were crushed by the Mexican government. The US sympathized with the Mexican government and started taking PLM leaders in the US into custody. Magón was fearful that he would be caught and be returned to Mexico, where he faced the possibility of execution.
