More than 300 Chinese immigrants are killed in the Torreón massacre when the forces of the Mexican Revolution led by Emilio Madero take the city of Torreón from the Federales.

The Torreón massacre was a massacre that took place from May 13 to May 15, 1911 in the Mexican city of Torreón, Coahuila. A total of 308 Chinese were killed, amounting to half the Chinese community in Torreón. The victims, accused of collusion with dictator Porfirio Díaz, were killed by a local mob and the revolutionary forces of Francisco I. Madero. A large number of Chinese homes and shops were looted and destroyed.
