<human>:  When did the Cultural Revolution start and when did it end?
<bot>: The Cultural Revolution began in 1966 and ended in 1976. It was a period of social and political upheaval in China, and the Chinese Communist Party tried to purge the country of "counter-revolutionaries" and "capitalist roaders". The Cultural Revolution was a time of extreme political and social chaos, but also a time of great creativity. Many Chinese artists and writers had their works censored during this time, but others were inspired to create works that have since become famous.
