TheOctober 1977 Thai coup d'état was a bloodless militarycoup which took place inThailand on 20 October 1977, staged by theRoyal Thai Armed Forces (RTAF).^[1] The coup was carried out under the nominal authority of AdmiralSangad Chaloryu of theRoyal Thai Navy, head of the National Administrative Reform Council (NARC),^[2] but it was effectively led by GeneralKriangsak Chamanan of theRoyal Thai Army, Supreme Commander of the RTAF.^[3] It led to the deposition of Prime MinisterThanin Kraivichien, who assumed the office following the1976 coup d'état (which was also led by Admiral Sangad and resulted in the establishment of the NARC^[4]), in theimmediate aftermath of theThammasat University massacre.^[5]: 91

The October coup was preceded by theMarch 1977 coup d'état attempt. Their attempted coup failed.^[6][7]

The military justified their intervention in October because Thanin's government had divided the country, had virtually no public support, the economic situation had worsened, and people in general disagreed with such a long-term suspension of democracy.^[8]

General Kriangsak assumed the office of Prime Minister, and served until his resignation in 1980.^[9]
