The plan of San Diego in 1915 was a revolutionary document that appeared in Texas and called for an uprising of the Mexican American population to recapture stolen lands from Mexico in 1848 and to restore the Mexican government into this lands, and to overthrow the United States government in Southern states, it also called for African Americans and Asian Americans to finish the Anglo American population over the age of sixteen and to restore Indian lands.
This document was never materialized, but it installed fear because the violence of the Mexican Revolution was spreading through the Southern states and resulted in raids where many Mexicans and Mexican Americans were killed by the Texas Rangers and the U.S. army. It also resulted in the Punitive Expedition of 1916 where General John Pershing went to Mexico to capture Pancho Villa.
