Of all the key dates in Thailand’s history, October 14th, 1973 stands out like none other. On that day, nearly 500,000 people marched along Rajadamnoen Avenue to protest the arrests of 13 students who had demanded a constitution from Field Marshall Thanom Kittikachorn.

October 14, 1973 was a revolution in Thai politics. The pro-democracy students had toppled the military regime to free the country from a string of military governments which had ruled Thailand since 1947.

For many years, the incident was not part of official Thai history. After 29 years of denial and evasion there is now a move to remember what many scholars now call modern Thailand’s “most important day”.
