During the French intervention, the lands had belonged primarily to Doña Luisa Ibarra de Zuloaga, who was closely associated with Empress Carlota. After the restoration of the republic, the lands, notably the ranches “La Chona” and “El Hormiguero” were seized by the government and placed under the control of Don Jerónimo Treviño, hero of the 1866 Battle of Santa Isabel. Mustered out Republican soldiers settled on the land having been given grants by the governor of Coahuila. Sister Cities
