Prayut Chan-o-cha is a Thai retired politician and army officer who became the 29th Prime Minister of Thailand from 2014 when he seized power in a military coup, to 2023. He also served as the minister of defence, a position he held in his own government from 2019 to 2023. Prayut served as Commander-in-Chief of the Royal Thai Army from 2010 to 2014 and led the 2014 Thai coup d'état which installed the National Council for Peace and Order (NCPO), the military junta which governed Thailand between 22 May 2014 and 10 July 2019.

On 22 May 2014, the Royal Thai Armed Forces, led by General Prayut Chan-o-cha, Commander of the Royal Thai Army (RTA), launched a coup d'état, the 12th since the country's first coup in 1932, against the caretaker government of Thailand, 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'. 7 years later, it had developed into the 2020 Thai protests to reform the monarchy of Thailand.
