who was the red guard and what did they do

The Red Guard was a mass student-led radical political movement in China during the late 1960s, which emphasized Mao Zedong's ideology of communist revolution. They were primarily composed of young students and intellectuals. They were mobilized by Mao Zedong to help him regain political control in the country during the Cultural Revolution.

The Red Guard were responsible for attacking and purging those who were perceived as counter-revolutionaries, including intellectuals, academics, government officials, and anyone else who was thought to be opposed to Mao's ideas. They also destroyed cultural artifacts, such as ancient temples, and attacked traditional Chinese culture as part of their campaign to eliminate the "four olds" (old ideas, old culture, old customs, and old habits).

The Red Guard's actions caused massive social upheavals in China, which caused significant damage to the country's social and intellectual fabric. Eventually, Mao lost control of the Red Guards, and the movement became increasingly factionalized and violent. The Red Guard eventually dissolved by the 1970s, as the Chinese government re-established control over the country and began to rebuild the society.
