Pol Pot was a political leader whose communist Khmer Rouge government led Cambodia from 1975 to 1979. During that time, an estimated 1.5 to 2 million Cambodians died of starvation, execution, disease or overwork. One detention center, S-21, was so notorious that only seven of the roughly 20,000 people imprisoned there are known to have survived. https://en.wikipedia.org/wiki/Pol_Pot https://www.history.com/topics/cold-war/pol-pot
