The party's General Secretary at the time was Pol Pot. The party led the deposed Democratic Kampuchea government. Its followers were generally called Khmer Rouge.
At the time of the formation of the PDK, the Khmer Rouge forces had been pushed back by the Vietnamese-backed KPRP government to an area near the Thai border. The PDK began cooperating with other anti-Vietnamese factions and formed the Coalition Government of Democratic Kampuchea in 1982.
Although Pol Pot relinquished party leadership to Khieu Samphan in 1985, he continued to wield considerable influence over the movement.
Ahead of the 1992/1993 elections, the PDK was largely succeeded by the Cambodian National Unity Party (CNUP),[4] which publicly stated its wish to participate in the elections but eventually did not register and vowed to sabotage the election. Subsequently, UNTAC decided not to conduct elections in areas under PDK control.[5] At the time it was estimated that approximately six percent of the population in Cambodia lived in areas under PDK control.[6]
