The Chinese massacre of 1871 was a racially motivated riot on October 24, 1871, when a mob of over 500 Caucasians entered Los Angeles' Chinatown to attack and eventually murder Chinese American residents of the city. The riots took place on Calle de los Negros (known colloquially as Nigger Alley), which later became Los Angeles Street. Every Chinese-occupied building on the block was ransacked and almost every resident was attacked or robbed. Estimates of the number of dead vary, but between 20 and 23 Chinese residents were killed. At the time, there were only 200 Chinese living in Los Angeles.
