The National Council for Peace and Order (NCPO; Thai: คณะรักษาความสงบแห่งชาติ; rtgs: Khana Raksa Khwam Sa-ngop Haeng Chat; abbreviated คสช) is the junta that has ruled Thailand since their 2014 Thai coup d'état on 22 May 2014. On 20 May 2014, the military had declared martial law nationwide in an attempt to stop the country's escalating political crisis, and to force the democratically elected government out. On 22 May, the military ousted the Yingluck Shinawatra government and formed the NCPO to take control of the country. The junta censored the broadcasting system in Thailand, suspended the constitution, and detained members of the Thai cabinet.
The original English name assumed by the junta was "National Peace and Order Maintaining Council" or "NPOMC". The name was later changed to "National Council for Peace and Order" or "NCPO" on 24 May 2014.
On 22 May 2014, the NCPO announced its composition and stated that its leader would exercise all powers and duties which the laws invest in the prime minister and the cabinet, until a new prime minister was elected or appointed.
On 23 May, the NCPO announced that short- and long-term national administrative policies would be determined by its leader. It assigned its members to government ministries and agencies.
On 24 May 2014, the NCPO dissolved the Senate and vested legislative power in its leader. It also ordered the judicial branch to operate under its directives. Later that day, it transferred Police General Adul Saengsingkaew, who was the Commissioner-General of the Royal Thai Police and also its deputy leader, to an inactive post in the office of the prime minister. Adul was replaced by Police General Watcharapol Prasarnrajkit.
On 26 May, King Bhumibol Adulyadej endorsed the coup, formally appointing General Prayut Chan-o-cha to "take charge of public administration" as of 24 May. The royal endorsement was seen as key to legitimising the coup.
