Field Marshal Sarit Thanarat (also spelt Dhanarajata; Thai: สฤษดิ์ ธนะรัชต์, pronounced [sā.rìt tʰā.ná.rát]; 16 June 1908 – 8 December 1963) was a Thai military officer who staged a coup in 1957, replacing Plaek Phibunsongkhram as Thailand's prime minister until Sarit died in 1963. He was born in Bangkok, but grew up in his mother's home town in Isan-speaking northeastern Thailand and considered himself from Isan. His father, Major Luang Ruangdetanan (real name Thongdi Thanarat), was a career army officer best known for his translations into Thai of Cambodian literature.
