1981 Thai military rebellion

The 1981 Thai military rebellion was a military coup attempt to consolidate power by the government of Prem Tinsulanonda, staged by Thai military leaders of Class 7 on 1 April 1981, but a counter-coup by Prem, Arthit Kamlang-ek, and support by the royal family on 3 April led to the coup's failure, turning it into a rebellion. In Thailand, it is known as the "Young Turk Rebellion" (Thai: กบฏยังเติร์ก, romanized: Kabot Yang Toek), referring to the group of military officers that led the coup, or more mockingly as the "April Fools' Day Rebellion" (Thai: กบฏเมษาฮาวาย, romanized: Kabot Mesa Hawai), referring to the date of the coup along with its failure.
