French Protectorate of Cambodia - World War II in Cambodia

World War II in Cambodia

After the Fall of France in 1940, Cambodia and the rest of French Indochina were ruled by the Axis-puppet Vichy France government and despite an invasion of French Indochina, Japan allowed French colonial officials to remain in their colonies under Japanese supervision. In December 1940, the French-Thai War erupted and despite French resistance against the Japanese backed Thai forces, Japan compelled French authorities to cede Battambang province to Thailand.

Japanese calls of "Asia for the Asiatics" found a receptive audience among Cambodian nationalists, although Tokyo's policy in Indochina was to leave the colonial government nominally in charge. When a prominent, politically active Buddhist monk, Hem Chieu, was arrested and unceremoniously defrocked by the French authorities in July 1942, the editors of Nagaravatta led a demonstration demanding his release. They, as well as other nationalists, apparently overestimated the Japanese willingness to back them, for the Vichy authorities quickly arrested the demonstrators and gave Pach Choeun, one of the Nagaravatta editors, a life sentence . The other editor, Son Ngoc Thanh, escaped from Phnom Penh to Tokyo.

In an effort to enlist local support in the final months of the war, the Japanese dissolved the French colonial administration on 9 March 1945, and urged Cambodia to declare its independence within the Greater East Asia Co-Prosperity Sphere. Four days later, King Sihanouk decreed an independent Kampuchea (the original Khmer pronunciation of Cambodia). Son Ngoc Thanh returned from Tokyo in May, and was appointed foreign minister. On 15 August 1945, the day Japan surrendered, a new government was established with Son Ngoc Thanh acting as prime minister. When an Allied force occupied Phnom Penh in October, Thanh was arrested for collaboration with the Japanese and was sent into exile in France to remain under house arrest. Some of his supporters went to north-western Cambodia, then still under Thai control, where they banded together as one faction in the Khmer Issarak movement.
