Jiang Qing, also known as Madame Mao, was a Chinese communist revolutionary, actress, and major political figure during the Cultural Revolution (1966–1976). She was the fourth wife of Mao Zedong, the Chairman of the Communist Party and Paramount leader of China. She used the stage name Lan Ping (藍蘋) during her acting career, and was known by many other names. Jiang was best known for playing a major role in the Cultural Revolution and for forming the radical political alliance known as the Gang of Four.

The Cultural Revolution, formally known as the Great Proletarian Cultural Revolution, was a sociopolitical movement in the People's Republic of China (PRC). It was launched by Mao Zedong in 1966 and lasted until his death in 1976. Its stated goal was to preserve Chinese communism by purging remnants of capitalist and traditional elements from Chinese society. Though it failed to achieve its main objectives, the Cultural Revolution marked the effective return of Mao to the center of power in China after his political sidelining, in the aftermath of the Great Leap Forward and the Great Chinese Famine.
