Thammasat University Massacre
Thammasat University, Phra ChaBy late 1976 moderate middle class opinion had turned away from the activism of the students, who had moved increasingly to the left. The army and the right-wing parties began a propaganda war against student liberalism by accusing student activists of being 'communists' and through formal paramilitary organizations such the Nawaphon, the Village Scouts, and the Red Gaurs, many of those students were killed. Matters came to a head in October when Thanom Kittikachorn returned to Thailand to enter a royal monastery, Wat Bovorn.
Tension between workers and factory owners became fierce, as the civil rights movement became more active after 1973. Socialism and leftist ideology gained popularity among intellectuals and the working class. The political atmosphere became even more tense. Workers were found hung in Nakhon Pathom after protesting against a factory owner. A Thai version of anti-communist McCarthyism spread widely. Whoever staged a protest could be accused of being part of a communist conspiracy.
In 1976, students protesters occupied the Thammasat University campus and held protests over the violent deaths of the workers and staged a mock hanging of the victims, one of whom allegedly bore a resemblance to Crown Prince Vajiralongkorn. Some newspapers the following day, including the Bangkok Post, published an altered version of a photo of the event, which suggested the protestors had committed lèse majesté. Rightist and ultra-conservative icons such as Samak Sundaravej blasted the protestors, instigating violent means to suppress them, culminating in the 6 October 1976 Massacre. The army unleashed the paramilitaries and mob violence followed, in which many were killed.
