The Battle of Cable Street was a riot that took place in Cable Street, Whitechapel in the East End of London, on Sunday 4 October 1936. It was a clash between the Metropolitan Police, sent to protect a march by members of the British Union of Fascists led by Oswald Mosley, and various anti-fascist demonstrators, including local anarchist, communist, Jewish and socialist groups. The majority of both marchers and counter-protesters travelled into the area for this purpose.
