Field Marshal Plaek Phibunsongkhram was a prominent Thai military leader and politician who served as the Prime Minister of Thailand during two significant periods: from 1938 to 1944 and again from 1948 to 1957. He played a crucial role in modernizing the country and promoting nationalism, emphasizing Thai culture and identity. Phibunsongkhram was known for his authoritarian rule and alignment with Japan during World War II. His government implemented various reforms, including infrastructure development and education improvements. However, his tenure also faced criticism for suppressing political dissent and limiting civil liberties.
