Partido Liberal Mexicano
Diaz agents backed by US authorities chased liberals in Texas, so they continued to move further and further north. On 28 September 1905, in Saint Louis, Missouri, United States, the Magón Flores group drafted the manifesto with which the Organizing Board of the Mexican Liberal Party was constituted. The tasks of the Organizing Board were to summon and articulate all the opposing forces to prepare the fight against the dictator.
