Around 1910, large numbers of Mexican immigrants settled in the "Segundo Barrio" (Second Ward), near industrial jobs for railroads and manufacturers of supplies for railroads. The Rusk Settlement House and El Campo Laurel lodge were two Second Ward organizations serving the emerging Mexican community in Houston. The Archdiocese of Galveston dispatched a missionary to the area, and later this initiative evolved into the Lady of Guadalupe Church. Several protestant churches in the area followed. Revolution in Mexico the same year changed the immigration dynamic. In some cases, war induced Mexican-Houstonians to return to their native country to join the fight or assist family, but as the war dragged on, immigration from Mexico to Houston increased, mostly from the northern states of Coahuila, Nuevo León, and San Luis Potosí. Civil unrest in Mexico persisted into the 1920s, promoting continued immigration and the development of a robust Mexican-American community in Houston.
