El Plan de San Diego
San Diego, TX
On January 6, 1915, nine men of Mexican descent gathered in San Diego, Texas, and signed a manifesto calling for armed insurrection to wrest the Southwest from the United States and forge a new nation — enlisting Mexican Americans, African Americans, Native Americans, and Japanese Americans. The plot was betrayed almost at once when a signer tried to recruit the wrong man, and no rising came on the appointed day. But near-daily raids that summer in the Lower Rio Grande Valley triggered a wave of extrajudicial killings, as law officers and vigilantes murdered hundreds, perhaps thousands, of ethnic Mexicans, prompting President Wilson to flood the border with troops.
