The Cultural Revolution (1966–1976) was one of the most violent political movements to have taken place in modern Chinese history. Sport was not immune from this political storm. In the first phase of the revolution (1966–1972), the country’s sport system was brought down by the Red Guards and revolutionary rebels. Athletes, coaches and officials who dared to challenge the Maoists were arrested and tortured, and suffered greatly as a result of their ‘counter-revolutionary’ status. In the second phase of the revolution (1972–1976), the Sports Ministry became a battlefront in the power struggle within the PRC leadership. This paper studies the relationships between sport, politics and power struggle during the Cultural Revolution. It points out that what happened in the Sports Ministry demonstrates how China’s sport system was linked to and affected by top-level power struggles and ideological conflicts. It also reflected how ordinary people’s lives were affected by the revolution.
