The protests started in Helwan after Egypt's defeat to Israel in the 1967 Six-Day War and quickly swept the country. The zenith of the protest movement occurred on 9–10 June 1967, when Gamal Abdel Nasser’s supporters rallied in their hundreds of thousands against his resignation which made his rescind his resignation. The movement itself lasted until March 1968 when the government used military forces to quell the movement.
