The 1923 Kraków riot was a violent riot that took place during a strike on 6 November 1923 in Kraków, Poland. The incident is also called the 1923 Kraków uprising, particularly by Marxist sources. Demonstrators took control of the Main Market Square area and disarmed some troops. Eventually troops and police were ordered to fire on the workers, though some soldiers refused. Three armored cars were used, one of which, named Dziadek ("Grandpa"), was captured by the workers in the Market Square area. Some 18–30 workers were killed, as well as 14 soldiers. No policemen died, but 31 were injured.
