Khmer Issarak in the context of "United Issarak Front"

The United Issarak Front (UIF) (in Khmer: សមាគមខ្មែរឥស្សរៈ, Samakhum Khmer Issarak, lit. 'Khmer Issarak Front') was a Cambodian anti-colonial movement 1950–1954, organized by the left-wing members of the Khmer Issarak movement. The UIF coordinated the efforts of the movement as of 1950, and waged war against the French Union forces. At the time of the Geneva Peace Conference in 1954, it is estimated that UIF controlled about half of the Cambodian territory.
