Bad Mexicans tells the dramatic story of the magonistas, the migrant rebels who sparked the 1910 Mexican Revolution from the United States. The magonistas were a motley band of journalists, miners, migrant workers, and more, who organized thousands of Mexican workers--and American dissidents--to their cause. Determined to oust Mexico's dictator, Porfirio Díaz, who encouraged the plunder of his country by U.S. imperialists such as Guggenheim and Rockefeller, the rebels had to outrun and outsmart the swarm of U. S. authorities vested in protecting the Diaz regime. The U.S. Departments of War, State, Treasury, and Justice as well as police, sheriffs, and spies, hunted the magonistas across the country. They lived in hiding, wrote in secret code, and launched armed raids into Mexico until they ignited the world's first social revolution of the twentieth century. Taking readers to the frontlines of the magonista uprising and the counterinsurgency campaign that failed to stop them, Kelly Lytle Hernández puts the magonista revolt at the heart of U.S. history.
