<span><span>The Cultural Revolution, formally the Great Proletarian Cultural Revolution, was a social-political movement that took place in the People's Republic of China from 1966 until 1976. Set into motion by Mao Zedong, then Chairman of the Communist Party of China, its stated goal was to preserve 'true' Communist ideology in the country by purging remnants of capitalist and traditional elements from Chinese society, and to re-impose Maoist thought as the dominant ideology within the Party. The Revolution marked the return of Mao Zedong to a position of power after the Great Leap Forward. The movement paralyzed China politically and significantly affected the country economically and socially.</span>

The holy roman emperor (Henry IV) wanted to make the church independent from secular rulers so he banned the practice of Lay Investiture. The pope (Gregory VII) excommunicated him and went to find a new emperor when Henry IV confessed to him he was a sinner and Gregory forgave him. But Henry was so butt hurt about it that he sent to roman military to kill the pope.
