"La Prensa" was founded on February 13, 1913, in San Antonio as a weekly newspaper by Ignacio Eugenio Lozano, Sr. (1886–1953), a prominent exile of Mexico, native of Nuevo Leon, and supporter of Porfirio Diaz leading up to, and throughout the Mexican Revolution. That same month, nine days later, Mexico's President Francisco I. Madero was assassinated. The era was coincident with a large influx of Mexican exiles in America who had fled after a series of revolutionary-related civil unrest. "La Prensa", according to historian Richard Griswold del Castillo, PhD, had two missions: (i) to serve as the voice of the Mexican exile community and (ii) to defend and represent the views of the wealthy Mexican exiles who favored Diaz. "La Prensa's" editorials strongly challenged Mexican public policy. The upshot was that its editorial positions mirrored the political ideologies of Lozano.
