Mao Zedong was a Chinese communist revolutionary who served as China's Chairman from 1949 until his death in 1976. He had four wives and 10 children total. Mao developed influential Marxist-Leninist theories known as Maoism and led the Communist Party of China to power. Supporters credit him with modernizing China, while critics argue he oversaw human rights abuses and policies that caused millions of deaths. Mao suffered health issues late in life and died of a heart attack in 1976 at age 82, after leaving a significant impact on both China and global communism.
