The Free Thai Movement was a resistance group formed during World War II, primarily composed of Thai citizens and expatriates. It aimed to oppose the collaboration of the Kingdom of Thailand with the Japanese Empire. The movement sought to promote democracy and national sovereignty, advocating for Thailand's independence from foreign influence. Members of the Free Thai Movement engaged in various activities, including espionage and propaganda efforts. They received support from the Allied Powers, particularly the United States and Britain, who provided resources and training. The movement played a significant role in shaping Thailand's post-war political landscape.
