What is "sangkum"

The Sangkum Reastr Niyum , literally the "community of the common people"; , usually translated as "People's Socialist Community"; commonly known simply as the Sangkum was a political organisation set up in 1955 by Prince Norodom Sihanouk of Cambodia. Though it described itself as a 'movement' rather than a political party (members had to abjure membership of any political group), the Sangkum retained control of the government of Cambodia throughout the first administration of Sihanouk, from 1955 to 1970.
