1957 Thai coup d'état

On 16 September 1957, Thailand experienced a military coup led by Field Marshal Sarit Thanarat. This bloodless coup ended the government of Prime Minister Plaek Phibunsongkhram. His administration had faced growing criticism for corruption, poor economic management, and political misconduct. The military claimed the coup was necessary to restore order and protect national unity during a time of increasing unrest. Sarit's swift takeover of Bangkok signaled a new phase of military power in Thai politics.

The coup stemmed from a power struggle among Thailand's ruling elite. Phibun was in rivalry with Police General Phao Siyanon, who had significant influence due to his control over the police force. Although Sarit had once supported Phibun, he later strengthened his position in the military and sought to marginalize both Phibun and Phao.

Earlier in 1957, national elections occurred amid claims of widespread fraud and intimidation. Phibun tried to manipulate the election to keep his grip on power. However, these irregularities sparked public outrage and eroded trust in the government, worsening the political crisis and leading to military action.

After the coup, Sarit became the leading political figure, although he initially chose not to take on the role of prime minister. His government concentrated on tightening military control, silencing dissent, and establishing a more centralized and authoritarian governing system. Sarit put a strong focus on economic growth and building closer ties with Western powers during the Cold War. The coup not only ended civilian rule under Phibun but also set a standard for military influence in Thailand's politics, shaping the country's governance for many years.
