Zhang Chunqiao
Backed by her husband, she was appointed deputy director of the Central Cultural Revolution Group (CCRG) in 1966 and emerged as a serious political figure in the summer of that year. At the 9th Party Congress in April 1969, she was elevated to the Politburo. By then, she had established a close political working relationship with the other members of what later became known as the Gang of Four—Zhang Chunqiao, Yao Wenyuan and Wang Hongwen. She was one of the most powerful and controversial figures in China during Mao's last years.
