These men were perhaps the most educated leaders in the history of Asian communism. Two of them, Khieu Samphan and Hou Yuon, earned doctorates from the University of Paris; Hu Nim obtained his degree from the University of Phnom Penh in 1965. In retrospect, it seems enigmatic that these talented members of the elite, sent to France on government scholarships, could launch the bloodiest and most radical revolution in modern Asian history. Most came from landowner or civil servant families. Pol Pot and Hou Yuon may have been related to the royal family. An older sister of Pol Pot had been a concubine at the court of King Monivong. Three of the Paris group forged a bond that survived years of revolutionary struggle and intraparty strife, Pol Pot and Ieng Sary married Khieu Ponnary and Khieu Thirith (also known as Ieng Thirith), purportedly relatives of Khieu Samphan. These two well-educated women also played a central role in the regime of Democratic Kampuchea.
