Khieu Chum

Most of all, Khieu Chum was critical of the instrumentalization of the Buddhism for political ends but he himself wrote some speeches for Lon Nol and regularly justified the end the monarchy on Buddhist grounds during his speeches broadcast on national radio. He was even criticized by Huot That as a revolutionary. Cronyism and association with the Republican government was severely judged by the Khmers Rouges once they entered Phnom Penh in April 1975, leading to his execution with other monks for alleged “CIA” sympathies and “enemy” activities.”

In 1970, Khieu Chom was ordained as the abbot of Wat Langka by Supreme Patriarch Huot That, a position which he kept until his assassination in 1975.

After the coup which capsized the Khmer Monarchy and installed a short-lived Khmer Republic led by Lon Nol and supported by the American government, Khieu Chum gained even more importance as a political monk at a time when he reach "the zenith of his career." Some even presume that he was "a member of a small group of people responsible for planning the Cambodian coup of 1970 which overthrew the monarchy." While he was supportive of the Republic and helped drafting the republican constitution, his conservative views were at odds with many policies imposed by Lon Nol. As such, he was considered a "Thanist", as he was a partisan of Son Ngoc Thanh. The committee he led in early March 1971 in presence of Lon Nol led to the dismissal of Sirik Matak and his replacement by Son Ngoc Thanh.

In 1969, Khieu Chum what is believed to be his spiritual legacy: Life is a Struggle (Khmer: ជីវិតតស៊ូ) where he showed that beyond his personal struggles and the toil of the Cambodian people, the character of the Khmer people would allow them to carry on.​ Two posthumous books of his were reprinted in 2001: Life is peace (ជីវិតសន្តិភាព) and The Problem of Life (បណ្ហាជីវិត). Buddhist novices in Cambodia still read these philosophical books for personal development as they have become classics in Cambodian literature.

Inspired from the work of Khmer linguists Ieu Koeus and Keng Vannsak, Khieu Chum also encouraged the renewal of Cambodian identity through a deeper knowledge of Khmer language. In 1962, he published a Khmer grammar which he complemented in 1966 with another manual, Our Grammar (Khmer: វេយ្យករណ៍យើង).

In 1942, Khieu Chom joined the Umbrella Revolution along with other nationalist monks such as Hiem Chieu in Phnom Penh who were opposed to the French protectorate. With his comrades Pang Khat and others, he was sent to jail and deported to Poulo Condor island. All these political prisoners were released at the end of the Second World War and Khieu Chom returned to his studies as a monk in Wat Langka.

Khieu Chum (Khmer: ខៀវ ជុំ Khmer pronunciation: [kʰiəw cum], 1907–1975) was a prominent Cambodian Buddhist monk and activist who was a member of a small group of people responsible for planning the Cambodian coup of 1970 which overthrew the monarchy and placed General Lon Nol as leader of a new Khmer Republic. After Cambodia achieved independence in 1953, Chum became an active figure in internal politics and is now considered one of the country's most significant political thinkers of the era.

Khieu Chum was born in S'ang District in the Province of Kandal. His year of birth is believed to be the year 1907 according to Cambodian Buddhist sources, rather than 1915, which is impossible as he was younger than Pang Khat who was born in 1910. His parents were both ordinary Khmer peasants.
