The March 1977 Thai coup d'état attempt was a military coup attempt against the military government of Thanin Kraivichien and junta leader Sangad Chaloryu, by Chalard Hiranyasiri on 26 March 1977, but failed within 12 hours. Chalard was executed one month later without trial, in retaliation of the killing of Arun Thavathasin, close friend of King Bhumibol Adulyadej.
