Phibunsongkhram Province
Phibunsongkhram Province was a former province of Thailand that existed between 1941 and 1946. It was created as a result of the annexation of Cambodian territory by Thailand following the 1940-41 Franco-Thai war. This province was named after Plaek Phibunsongkhram, prime minister of Thailand at that time. The province was dissolved and returned to France in 1946.
History
The province was formed in 1941 after France ceded Siem Reap, Oddar Meanchey and Banteay Meanchey provinces to Thailand as a result of the Franco-Thai war. The province was dissolved in 1946 and returned to France after the post-war French government threatened to veto Thailand's entry into the UN.Administrative divisions
