A woman participates in an anti-Nazi rally. On 30 April 1978, thousands gathered in Trafalgar Square for an anti-Nazi rally. People were responding to a rise in racism that had been encouraged by organisations such as the National Front. The crowd marched from the West End through to Victoria Park, Hackney for a concert staged in the name of 'Rock Against Racism'. Performing there to an estimated 100,000 people were The Clash, X-Ray Spex, Steel Pulse and Tom Robinson.
