Plan De San Diego: Tejano Rebellion, Mexican Intrigue

The Plan of San Diego, a rebellion proposed in 1915 to overthrow the U.S. government in the Southwest and establish a Hispanic republic in its stead, remains one of the most tantalizing documents of the Mexican Revolution. The plan called for an insurrection of Mexicans, Mexican Americans, and African Americans in support of the Mexican Revolution and the waging of a genocidal war against Anglos. The resulting violence approached a race war and has usually been portrayed as a Hispanic struggle for liberation brutally crushed by the Texas Rangers, among others.

The Plan de San Diego: Tejano Rebellion, Mexican Intrigue, based on newly available archival documents, is a revisionist interpretation focusing on both south Texas and Mexico. Charles H. Harris III and Louis R. Sadler argue convincingly that the insurrection in Texas was made possible by support from Mexico when it suited the regime of President Venustiano Carranza, who co-opted and manipulated the plan and its supporters for his own political and diplomatic purposes in support of the Mexican Revolution.

The study examines the papers of Augustine Garza, a leading promoter of the plan, as well as recently released and hitherto unexamined archival material from the Federal Bureau of Investigation documenting the day-to-day events of the conflict.
