On 22 May 2014, the Royal Thai Armed Forces, led by General Prayut Chan-o-cha, the commander-in-chief of the Royal Thai Army, launched a coup d'état, the twelfth since the country's first coup in 1932, against the caretaker government following six months of political crisis. The military established a junta called the National Council for Peace and Order (NCPO) to govern the nation. The coup ended the political conflict between the military-led regime and democratic power, which had been present since the 2006 Thai coup d'état known as the "unfinished coup". Seven years later, it developed into the 2020–2021 Thai protests to reform the monarchy of Thailand.
After dissolving the government and the Senate of Thailand, the NCPO vested executive and legislative powers in its leader and ordered the judicial branch to operate under its directives. In addition, it partially repealed the 2007 constitution, save the second chapter that concerned the king, declared martial law and curfew nationwide, banned political gatherings, arrested and detained politicians and anti-coup activists, imposed Internet censorship in Thailand and took control of the media.
The NCPO issued an interim constitution that granted itself amnesty and sweeping power. The NCPO also established a military-dominated national legislature which later unanimously elected Prayut as the new prime minister of the country.
In February 2021, government ministers Puttipong Punnakanta, Nataphol Teepsuwan and Thaworn Senniam were found guilty of insurrection during protests that led to the 2014 coup d'état.
Background
Thailand's politics system changed from absolute monarchy to democracy in the Siamese revolution of 1932. More than 10 coups occurred before the 1997 constitution of Thailand, widely hailed as a landmark in Thai democratic constitutional reform, was enacted. Four years later, Thaksin Shinawatra had become the first prime minister of Thailand to complete a full term in office, and his rule is generally agreed to have been one of the most distinctive in the country's modern history. After 2005–2006 Thai political crisis led by the People's Alliance for Democracy, Thaksin was overthrown in a military coup on 19 September 2006, accused of lèse-majesté. His Thai Rak Thai Party was outlawed and he was barred from political activity. Thaksin has since lived in self-imposed exile. He was sentenced in absentia to two years in jail for abuse of power. From abroad he has continued to influence Thai politics, through the People's Power Party that ruled in 2008, and its successor organisation Pheu Thai Party, as well as the United Front for Democracy Against Dictatorship or Red Shirts movement that were cracked down by Anupong Paochinda and Prayut Chan-o-cha's army, together with the Abhisit Vejjajiva and Suthep Thaugsuban's Democrat Party government, in 2010.
In the 2011 general election, Yingluck Shinawatra and the Pheu Thai Party (PTP) won a landslide victory and formed the government with Yingluck as prime minister. Anti-government protests, led by former Democrat Party secretary general Suthep Thaugsuban, began in November 2013. Suthep later formed the People's Democratic Reform Committee (PDRC) for the purpose of demanding the establishment of an unelected "people's council" to supervise "political reform", seen as a dismissal of Thaksin power. Suthep told PDRC supporters that he had been in talks with General Prayut Chan-o-cha since 2010 about how to exclude Thaksin from power. Similarly, Reuters reported in December 2013 that close friends of Prayut, former army chief Anupong Paochinda and General Prawit Wongsuwon, were supporters of the PDRC.
Pro-government groups, including the Red Shirts, held mass rallies in response. Violence occasionally occurred, resulting in a number of deaths and injuries. In December 2013, Yingluck dissolved the House of Representatives and scheduled a general election for 2 February 2014. Disrupted by the anti-government protesters, the election was not completed on that day. The Constitutional Court then nullified the election on 21 March 2014. On 7 May 2014, the Constitutional Court unanimously removed Yingluck and nine other senior ministers from office over the controversial transfer of a top security officer in 2011. The remaining ministers selected Deputy Prime Minister and Minister of Commerce Niwatthamrong Boonsongpaisan to replace Yingluck as caretaker prime minister as protests continued.
Suthep claimed that before declaring martial law, Prayut told him that "Khun Suthep and your masses of PDRC supporters are too exhausted. It's now the duty of the army to take over the task".
Immediately prior to the coup
Martial law imposition
The RTA intervened on 20 May 2014, when its commander, General Prayut, exercised the power under the act promulgated by King Vajiravudh (Rama VI) entitled Martial Law, BE 2457 (1914), to impose martial law nationwide from 03:00. He said through a television pool that the imposition of martial law was due to continuous violence from both sides and was for the purpose of allowing the army to restore and maintain the peace.
After imposing martial law, General Prayut ordered the dissolution of the Centre for Administration of Peace and Order, a police body formed by the caretaker government to resolve the crisis. He then established a Peace and Order Maintaining Command (POMC) with himself as its commander. Charged with the duty to "restore peace to the people from all sides without delay", the POMC was initially given the power to "prevent, suppress, abate and resolve" any situation affecting national security, to enforce every provision of the martial law, and to summon any person. General Prayut also ordered the personnel of the police, navy, air force and Ministry of Defence to be subject to the POMC.
In Bangkok, soldiers were stationed in many places and the main roads were blockaded. The military retook the Government House from the PDRC protesters and seized all television stations in Bangkok and some other parts of the country before shutting down some stations, including those of the PDRC and the Red Shirts. General Prayut later ordered all media to replace their regular programs with the POMC programs whenever he required. and imposed a ban on publishing information which might affect the military's mission. He also directed all government agency chiefs to report to him.
On 21 May 2014, the POMC established an Internet censorship task force and ordered Internet service providers to report to it in order to control online content.
The caretaker government complained that it had not been consulted about the martial law-related decisions of the army. The army claimed that the move was not a coup d'état and that the government remained in office.
Unsuccessful talks
After its establishment, the POMC held talks with rival groups for two days in an attempt to find resolution. It was reported that the participants were of conflicting opinions and no agreement could be adopted. During talks, the caretaker government was requested by the Election Commission to resign. The government denied the request, saying it was required by the constitution to stay in office. The 2007 constitution prescribed that the cabinet vacates office en bloc upon dissolution of the House of Representatives but it shall remain in office and continue to function until a new cabinet takes office.
On the afternoon of 22 May 2014, the POMC held another talk at the Thai Army Club on Vibhavadi Rangsit Road The talk had proceeded for five hours without reaching agreement, whilst the government maintained that it bore a legal duty to remain in office. At the meeting, General Prayut eventually said to Minister of Justice Chaikasem Nitisiri who led the government representatives: "The talk knows no end because you all only speak about the law. [...] The government insists that it won't resign, right?" Chaikasem replied: "Not at this moment". General Prayut then told the meeting that "Sorry, I must seize power" and ordered the detention of the cabinet members as well as the leaders of the PDRC, Red Shirts, and political parties who attended the talk, much to the dismay of the media representatives who were present. They were held at the headquarters of the 1st Infantry Regiment of the King's Guard, in Phaya Thai District.
Coup
Launch On the evening of 22 May 2014, General Prayut announced through a televised address that the armed forces were assuming control of national administration, formally launching a coup d'état against the caretaker government and establishing the NCPO to rule the state.
Later that night, the NCPO repealed the 2007 constitution, save the second chapter which deals with the king. In addition, it formally ordered the dissolution of the caretaker government, but the Senate as well as all other state agencies, including the courts and the independent organs, were kept intact. The NCPO declared its composition as follows:
General Prayut (RTA Commander) as its leader, General Thanasak Patimaprakorn (Chief of Defence Forces), Admiral Narong Pipathanasai (Royal Thai Navy Commander), Air Chief Marshal Prajin Juntong (Royal Thai Air Force Commander), and Police General Adul Saengsingkaew (Royal Thai Police Commissioner General), as its deputy leaders, General Udomdet Sitabut (RTA Deputy Commander) as its secretary general.
The NCPO then announced that its leader would exercise all powers and duties which the laws invest in the prime minister and the cabinet, until there was a new prime minister. It placed its members in charge of government ministries and equivalent agencies.
On 24 May 2014, the NCPO dissolved the existing Senate and granted legislative powers to its leader. It ordered the judicial branch to operate under its directives. It transferred Police General Adul to an inactive post in the Office of the Prime Minister and replaced him with Police General Watcharapol Prasarnrajkit. Adul was seen as a loyalist of the deposed government.
Arrest and detention of public figures Immediately after the coup was launched, caretaker Prime Minister Niwatthamrong, who did not attend the talks, left his office at the Ministry of Commerce so as to avoid being apprehended by the military. The NCPO ordered him and the cabinet members who were not detained to report to the military that day. It was reported that Niwatthamrong attempted to establish a government-in-exile at the United States embassy in Bangkok, but the embassy denied the report.
On the night of 22 May 2014, military officers detained additional politicians, including Chalerm Yubamrung and his sons. The following day, the NCPO summoned PTP members and Shinawatra family members, including Yingluck. Niwatthamrong and Yingluck surrendered themselves to the NCPO on that day. Yingluck was detained at an undisclosed "safe house". The NCPO said it released her on 25 May.
