The term ‘Prime Minister’ is used loosely to refer to the parliamentary Head of State- as other terms are used in Cambodian political history.
There may be major gaps in some of the profiles- which are taken from Khmer, French and English language sources. Some of the dates and days in office may not be totally correct. The names and dates in office are taken from WORLDSTATESMAN and may not always tally with other sources. Also note that some of the terms and positions have been translated from Khmer into French and then into English, so may be different to the standard.
Yem Sambaur
12 Feb 1949 – 20 Sep 1949: 220 days
29 Sep 1949 – 28 Apr 1950: 211 days (total 431 days)
Born February 2, 1913 in Kompong-Svay, Battambang. His father was a lawyer from Kampong-Cham. Yem Sambour studied at Sisowath high school in Phnom-Penh then at Albert Sarraut high school in Hanoi. He obtained the baccalaureate in 1935.
He married on May 1, 1939, and had 8 children: Syvana, Dararoat, Kirirum, Borumraot, Sereyroat, Moniroat, Bopharoat, Phalaroat.
In 1939 he entered the Cambodian magistracy, working as Deputy Commissioner of the King at the Sala Outor (Court of Appeal), the President of the Cambodian Courts of Kompong Chhnang, then of Kompong-Thom until the Japanese coup de force of 9 March 1945.
He was appointed as head of the Cambodian National Police at the beginning of 1947.
He joined the Democratic Party in April 1946 and was elected MP for Kampong Chhnang in the elections of December 1947, and was Secretary of State for the Interior, in charge of the national police under the cabinet of Chhean Vam (February 21 – August 14, 1948).
On November 19, 1948, he resigned from the Democratic Party and was active in overthrowing the Penn Nouth government.
With the support of the king, he obtained the investiture of the National Assembly to form a new cabinet (February 12 to September 19, 1949) of which he was President of the Council, Minister of the Interior and of Information. He was increasingly opposed by the Democrats, who pressured King Sihanouk to dissolve the national assembly and hold elections, and faced popular criticism for his plans to open a casino.
Sihanouk dissolved the assembly in September 1949, but his cabinet was chaired by Ieu Koeus from September 20 to 28. Just over a week later Yem Sambour regained his position (in a dissolved National Assembly) from September 29 1949 to May 2, 1950, with the additional functions of Minister of Interior and National Defense.
He accompanied the king to France in October 1949 for the signing of the Franco-Khmer treaty which took place on November 8, 1949.
He founded ‘le parti du Redressement National’, the National Redressment Party in April 1950 with former liberals like Khouth Koeun, and former Democrats including Ray Lomuth and Phelk Phoeun, however they failed to win votes in the elections of 1951 and 1955.
In June 1952, following the distribution of leaflets criticizing the National Assembly and the Democratic Party government of Huy Kanthoul, police conducted a search of his home. Weapons were found and he was arrested on June 8.
The King intervened to get him released, but Huy Kanthoul refused. Sihanouk then dissolved the government, dismissing Huy Kanthoul on June 15, 1952 and Yem Sambaur was released on June 24, 1952.
After the 1970 ousting of Sihanouk, Sambaur wrote an essay defending the National Assembly’s termination of support for the monarch.
His other roles included:
-Inspector of Finances in November 1952.
-Minister of National Economy in the cabinet of Chan Nak (November 23, 1953 – April 6, 1954).

He later became the consul in Haiti and died in Paris in 1989.
Ieu Koeus
20 Sep 1949 – 29 Sep 1949: 9 days
Ieu Koeus was born in 1905 in Sangkè district, Battambang province and was educated at Kandal Pagoda and at primary school
in Battambang province. He continued his secondary education at Sisowath College in Phnom Penh. He studied at the Hanoi Business School, graduating in 1927.
He worked for Denis Frère in Phnom Penh and the Memot rubber plantation and married in 1929. He had two children.
From 1932 to 1942, he worked in Battambang. From 1942 to 1945, he set up a pharmacy depot and a soap factory.
In 1945 he became Deputy Prime Minister of the Economy. A year later he became one of the founders of the Democratic Party and was provisionally appointed as president of the National Assembly to establish the draft constitution (placing Cambodia as a constitutional monarchy). From 1947-1949, he was president of the National Assembly.
From September 20 to 28, 1949, he was appointed Prime Minister and Minister of the Interior for just 9 days, and was succeeded by his predecessor and rival Yem Sambaur. Towards the end of 1949, he accompanied King Sihanouk to France.
On returning to Phnom Penh, during the closing session of the Democratic Party on January 14, 1950, he was the victim of a grenade attack and died. The perpetrators were never caught- the French, Khmer Issarak rebels, Sihanouk’s own security forces and even the Democrats have been implicated, but no charges were ever made.
Khmer history sources talk of a fundraising campaign to construct a stupa to honor Ieu Koeus next to that of his friend and political mentor Sisowath Youtevong.
Despite opposition, an overwhelming majority of Democrat lawmakers voted to pass a special law, forcing both townspeople and farmers to pay a contribution of five French Francs per household to contribute to the construction of the stupa. However, on completion, the stupa was somewhat modest- and although previous promises had stated that any remaining money would be transferred over to the state budget- a sizeable amount of money raised vanished.
The period between the death of Prince Youtevong in 1947 and the death of Ieu Koeus in 1948 is described by Sakou Samoth in his French language work HOMMES ET HISTOIRE DU CAMBODGE
“After the death of Prince Youtevong, the Democratic Party elected the grandson of King Sisowath, Prince Sisowath Vachhayavong (alternatively spelled Watchayavong), to be Prime Minister from 25 July 1947 to 20 February 1948.
Afterwards, the party elected Chhean Vam to succeed Prince Sisowath Vachhayavong. However, due to some infighting, the Prime Minister found his power insufficient and could not get things done. He asked for more power but the request was turned down.
Chhean Vam was overthrown on that issue in 14 August 1948 and Penn Nouth was elected as the next Prime Minister. He did not remain long at the head of his cabinet because Yem Sambaur, a former member of the Democratic Party, accused Penn Nouth of corruption. Yem Sambaur had left the Democratic Party to form his own minority grouping. Inexplicably, Yem Sambaur was chosen as the next Prime Minister on 12 February 1949 to replace Penn Nouth. How could this happen since the Democratic Party had the majority of the vote? The only reason this curious event could be explained was that the members of the Democratic Party became jealous of each other and preferred to see somebody from the outside instead of one of their own becoming Prime Minister.
After Yem Sambaur became Prime Minister, the Democrats started to have second thoughts and they finally passed a motion of censure against the Prime Minister- the nature of the censure was not clear. Because of this action, on 18 September 1949 King Norodom Sihanouk dissolved the National Assembly and signed a treaty with France granting some independence for Cambodia.
The treaty granted Khmer people most of administrative functions within Cambodia. In addition, the provinces of Battambang and Siem Reap that the French recovered from the Thai were given to the Cambodian government for self-governing rule with its own armed forces without any French interference. This was called the autonomous zone, similar to the autonomous zone of Pailin that Hun Sen granted to the remnants of Khmer Rouge. (These areas were also the areas where rebel group the Khmer Issarak- forerunner of the Khmer Rouge would be most active)
However, on matters of foreign policy, the Cambodian government had to coordinate its actions and decision making with the French Union. The French retained most of the judicial systems, finances, and customs. Outside Battambang and Siem Reap, France retained military operations. The reason the French wanted to retain military operations on other parts of Cambodia was because they felt more of a threat coming from Vietnam than Thailand, a threat that could break the French Union.
According to the Constitution at the time, in the event of the dissolution of the National Assembly, the President of the Assembly would become the chief executive pending the holding of new elections. At the time, Ieu Koeus was President of the Assembly. Unfortunately, he was assassinated in January 1950. Theories abounded on who assassinated Ieu Koeus. Some claimed it was Yem Sambaur himself who had a hand behind the whole affair while some pointed the fingers at Prince Norindeth. However, this case had never been resolved and still remains a mystery to this day.“
