The Democrat Party (; ) is a Thai political party. The oldest party in Thailand, it was founded as a royalist party, and now upholds a conservative and pro-market position. The Democrat Party made its best showings in parliament in 1948, 1976, and 1996. It has never won an outright parliamentary majority. The party's electoral support bases are southern Thailand and Bangkok, although election results in Bangkok have fluctuated widely. Since 2004, Democrat candidates won three elections for the governorship of Bangkok. From 2005 to 2019, the Democrat Party was led by Abhisit Vejjajiva, former prime minister. Names The Thai name of the party, Prachathipat (ประชาธิปัตย์), is derived from the word prachathipatai (ประชาธิปไตย) which means 'democracy', 'democratic' or 'democrat'. The party said it wanted the term to mean the people in whom democracy is vested. History Party founding The Democrat Party was founded by Khuang Aphaiwong on 5 April 1946, but the party considers 6 April as the party's founding day, to coincide with Chakri Memorial Day, as a conservative and royalist party, following the January 1946 elections. Early members included royalists opposed to Pridi Phanomyong and former Seri Thai underground resistance members. The party competed against the parties affiliated with Pridi Phanomyong and the Progressive Party of brothers Seni and Kukrit Pramoj. In the January 1946 elections, the Pridi-led coalition had won a majority in parliament. However, Pridi declined the nomination as prime minister and the parliament appointed Khuang as premier. Khuang resigned in March 1946, after being defeated on a bill, and was replaced by Pridi. The smaller Progress Party later merged with the Democrat Party. Accusation against Pridi Phanomyong After the death of King Ananda Mahidol in 1946, the Democrat Party accused Pridi of having been the mastermind behind the king's death and spread this propaganda throughout the capital. Seni Pramoj's wife told the US chargé d'affaires that Pridi had the king assassinated, and Democrat Party members spread the same rumor to the British Embassy. A few days after the king's death, a Democrat MP yelled out, "Pridi killed the King!" in the middle of a crowded theater. November 1947 coup and the 1949 Constitution By the time of the elections of August 1946, the Democrat Party was backed by royalists like Prince Upalisarn Jubala, Srivisarn Vacha, Sridhamadibes, Borirak Vejjakarn, and Srisena Sombatsiri. Except for Prince Upalisarn Jubala, all of these figures would become Privy Councilors to
