The Geneva agreement also stipulated that general elections should be held in Cambodia during 1955 and that the International Control Commission should monitor them to ensure fairness. Sihanouk was more determined than ever to defeat the Democrats (who, on the basis of their past record, were expected to win the election). The king attempted unsuccessfully to have the constitution amended. On March 2, 1955, he announced his abdication in favor of his father, Norodom Suramarit. Assuming the title of samdech (prince), Sihanouk explained that this action was necessary in order to give him a free hand to engage in politics.

To challenge the Democrats, Prince Sihanouk established his own political machine, the oddly named Sangkum Reastr Niyum (Popular Socialist Community), commonly referred to as the Sangkum. The name is odd because its most important components were right-wing parties that were virulently anticommunist. The Sangkum's emergence in early 1955 unified most right-wing groups under the prince's auspices. In the September election, Sihanouk's new party decisively defeated the Democrats, the Khmer Independence Party of Son Ngoc Thanh, and the leftist Pracheachon (Citizens') Party, winning 83 percent of the vote and all of the seats in the National Assembly.

Khmer nationalism, loyalty to the monarch, struggle against injustice and corruption, and protection of the Buddhist religion were major themes in Sangkum ideology. The party adopted a particularly conservative interpretation of Buddhism, common in the Theravada countries of Southeast Asia, that the social and economic inequalities among people were legitimate because of the workings of karma (see Buddhism , ch. 2). For the poorer classes, virtuous and obedient conduct opened up the possibility of being born into a higher station in a future life. The appeal to religion won the allegiance of the country's many Buddhist priests, who were a particularly influential group in rural villages.

As the 1960s began, organized political opposition to Sihanouk and the Sangkum virtually had disappeared. According to Vickery, the Democratic Party disbanded in 1957 after its leaders--who had been beaten by soldiers--requested the privilege of joining the Sangkum.

Despite its defense of the status quo, especially the interests of rural elites, the Sangkum was not an exclusively right-wing organization. Sihanouk included a number of leftists in his party and government. Among these were future leaders of the Khmer Rouge. Hu Nim and Hou Yuon served in several ministries between 1958 and 1963, and Khieu Samphan served briefly as secretary of state for commerce in 1963.

Sihanouk's attitude toward the left was paradoxical. He often declared that if he had not been a prince, he would have become a revolutionary. Sihanouk's chronic suspicion of United States intentions in the region, his perception of revolutionary China as Cambodia's most valuable ally, his respect for such prominent and capable leftists as Hou, Hu, and Khieu, and his vague notioc46 ions of "royal socialism" all impelled him to experiment with socialist policies. In 1963 the prince announced the nationalization of banking, foreign trade, and insurance as a means of reducing foreign control of the economy. In 1964 a state trading company, the National Export-Import Corporation, was established to handle foreign commerce. The declared purposes of nationalization were to give Khmer nationals, rather than Chinese or Vietnamese, a greater role in the nation's trade, to eliminate middlemen and to conserve foreign exchange through the limiting of unnecessary luxury imports. As a result of this policy, foreign investment quickly disappeared, and a kind of "crony socialism" emerged somewhat similar to the "crony capitalism" that evolved in the Philippines under President Ferdinand Marcos. Lucrative state monopolies were parceled out to Sihanouk's most loyal retainers, who "milked" them for cash.

Sihanouk was headed steadily for a collision with the right. To counter charges of one-man rule, the prince declared that he would relinquish control of candidate selection and would permit more than one Sangkum candidate to run for each seat in the September 1966 National Assembly election. The returns showed a surprising upsurge in the conservative vote at the expense of more moderate and left-wing elements, although Hou, Hu, and Khieu were reelected by their constituencies. General Lon Nol became prime minister.

Out of concern that the right wing might cause an irreparable split within the Sangkum and might challenge his domination of the political system, Sihanouk set up a "counter government" (like the British "shadow cabinet") packed with his most loyal personal followers and with leading leftists, hoping that it would exert a restraining influence on Lon Nol. Leftists accused the general of being groomed by Western intelligence agencies to lead a bloody anticommunist coup d'état similar to that of General Soeharto in Indonesia. Injured in an automobile accident, Lon Nol resigned in April 1967. Sihanouk replaced him with a trusted centrist, Son Sann. This was the twenty-third successive Sangkum cabinet and government to have been appointed by Sihanouk since the party was formed in 1955.
