On October 14, 1973 a massive popular uprising in Bangkok, led by university students, overthrew the military dictatorship of Field Marshal Thanom Kittikachorn, forcing him and his ruling clique into exile and briefly opening Thailand to democracy. Discontent with the Thanom regime, which had entrenched itself through Thanom's own 1971 self-coup, had been building over corruption, a notorious military poaching scandal, and the arrest of students and activists demanding a constitution. In early October the detention of student and faculty leaders triggered mass demonstrations; by October 13 a rally at the Democracy Monument had swelled to hundreds of thousands.
On October 14, after student leaders met a royal representative and began to disperse, clashes with police and soldiers erupted, and troops opened fire, with helicopters firing on Thammasat University; sources record 66 to 77 killed and over 800 wounded. The army commander refused further force, and King Bhumibol, who had signaled support for the protesters, announced Thanom's resignation. Calm returned only when it was announced that Thanom, his son Colonel Narong, and deputy Praphas Charusathien, the three tyrants, had fled the country.

The popular uprising of 14 October 1973 was a watershed event that ended the ruling military dictatorship of Thanom Kittikachorn and altered the Thai political system; violence continued on 15 October, and only when it was announced that Thanom, Praphas, and Thanom's son Colonel Narong Kittikachorn had fled the country did calm return to Bangkok.

In early October mass student demonstrations prompted by the arrest of 13 students and faculty forced Thanom to agree to a constitutional government, but tensions escalated on 14 October when police and military opened fire on a demonstration near the Grand Palace, killing 66 and wounding 876, after which King Bhumibol announced over radio and television that Thanom had resigned, and fighting ended on 15 October when it was announced that Thanom, Narong, and Praphas had fled Thailand.
Violence between police and students escalated, culminating on October 14, 1973 when government forces killed more than a hundred protestors, after which the army's commander General Kris Sivara refused to use additional force and Thanom and Praphas acceded to the urging of the king to go into exile, an event most Thai consider even more important than the 1932 coup that ended absolute monarchy.

Editorial Note
Arc closer: this October 14, 1973 uprising CLOSES the thread of Thanom's own November 17, 1971 self-coup (enriched in batch 23); it ended his and the three tyrants' rule. Killings protocol applied: the death toll is given as reported and attributed, with sources ranging from 66 (Wikipedia, Thanom) and 77 (Grokipedia, Bangkok Post) to more than one hundred (Britannica), recorded as a range rather than resolved to a single figure, with over 800 wounded. Fate coding: Thanom, Praphas, and Narong fled the country and were not physically harmed, matching the dataset fate. Coding note: the dataset labels this a popular revolt, accurately, as a student-led mass uprising forced the regime out, with King Bhumibol's intervention decisive. Arc forward: Thanom's 1976 return from exile sparked the October 6, 1976 Thammasat massacre and a return to military rule, separate later events.
Cross-Reference
Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
Identifiers for finding this same event in the other datasets:
Coup Atlas research identifies the target as: Field Marshal Thanom Kittikachorn (with Praphas Charusathien and Narong Kittikachorn), overthrown by the October 14, 1973 uprising and forced into exile; they were not physically harmed and fled the country..
Baseline coding: Incumbent executive removed from power. Recorded leader fate: deposed; fled the country. The baseline file does not name individual targets; researched names are kept in a separate layer.
