Pol Pot, leader of the Cambodian Communist Party

By 1962, Pol Pot had become leader of the Cambodian Communist Party and was forced to flee into the jungle to escape the wrath of Prince Norodom Sihanouk, leader of Cambodia. In the jungle, Pol Pot formed an armed resistance movement that became known as the Khmer Rouge (Red Cambodians) and waged a guerrilla war against Sihanouk's government.

In 1970, Prince Sihanouk was ousted, not by Pol Pot, but due to a U.S.-backed right-wing military coup. An embittered Sihanouk retaliated by joining with Pol Pot, his former enemy, in opposing Cambodia's new military government. That same year, the U.S. invaded Cambodia to expel the North Vietnamese from their border encampments, but instead drove them deeper into Cambodia where they allied themselves with the Khmer Rouge.
