The Battle of South Street riot took place on 9 October 1934.
Members of the British Union of Fascists and various anti-fascist protesters clashed following a meeting of Fascists at the Pier Pavilion. The riot involved a series of clashes along and close to the length of South Street from the Pier Pavilion and the Royal Arcade at its southern end to the junctions with Warwick Street and Market Street further north.
