Bad Mexicans tells the dramatic story of the magonistas, the migrant rebels who sparked the 1910 Mexican Revolution from the United States. Led by a brilliant but ill-tempered radical named Ricardo Flores Magón, 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, the rebels had to outrun and outsmart the swarm of US authorities vested in protecting the Diaz regime. The US Departments of War, State, Treasury, and Justice, as well as police, sheriffs, and spies, hunted the magonistas across the country.

But the magonistas persevered. 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 listeners 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 US history. Long ignored by textbooks, the magonistas threatened to undo the rise of Anglo-American power, on both sides of the border, and inspired a revolution that gave birth to the Mexican-American population, making the magonistas' story integral to modern American life.
