led another coup while dissolving parliament, abrogating the constitution, and ruling by revolutionary council. For the next nine years, there were no elections in Thailand, and the Democrat Party was dormant. Thanom Kittikachorn's rule through military power Thanom Kittikachorn, who had succeeded Sarit after his death, was pressured to promulgate a democratic constitution on 20 June 1968, and hold elections in February 1969. Parties affiliated with Thanom won the election, and the Democrats joined the opposition due to their anti-dictatorship stance. Thanom, his son Narong, and his brother-in-law Praphas Charusathien became known as the "three tyrants". They later executed a coup against their own government on 17 November 1971, abrogating the constitution and running the kingdom through a National Executive Council.
