The roots of the Cultural Revolution date back to the early 1960s. After the catastrophic Great Leap Forward, in which more than 20 million people died, Chairman Mao Zedong decided to take a less active role in governing the country. More practical, moderate leaders, such as Vice-Chairman Liu Shaoqi and Premier Zhou Enlai, introduced economic reforms based on individual incentives—such as allowing families to farm their own plots of land—in an effort to revive the battered economy. Mao detested such policies, as they went against the principles of pure communism in which he so firmly believed. Nevertheless, China's economy grew strongly from 1962 to 1965 with the more conservative economic policies in place.
