Strong anti-foreigner sentiment emerged during the Mexican Revolution (1910-1920) with its notion of national pride, 'Mexicanidad'. Chinese immigrants were accused of taking jobs and women away from Mexicans. The prosperous and industrious Chinese community of Torréon was decimated in May 1911. Rebels entered the city on May 13, trampled and stationed themselves on Chinese vegetable garden land, killing amost 100 Chinese workers. But the worst came in the next few days when new contingents of rebels arrived. Augmented by thousands of poor and freed prisoners from Torréon, the mob attacked foreign properties, but made their physical attacks almost exclusively on Chinese men. Over 200 defenseless Chinese were massacred. A few Japanese were also killed "owing to similarity of features."
