政治迫害
Isan politicians tended to be mistrustful of Bangkok, believed in decentralisation of government and promoted strong development of regional economies and tended to be more leftist than the parties in power. Political repression of Isan included the assassination of political leaders in the 1930s and 1950s, the disrobement of monks in the 1970s critical of the government's role in the sangha and the return of military leaders. Crackdowns of political dissidents occurred throughout the 1960s, 1970s and 1980s until the threat of communism was diminished. The continued outlawing of parties supported by or purportedly funded by Thaksin Shinawatra, who was widely popular in Isan, was seen as continued affront to both democracy in Thailand and representation of Isan people in Thai politics, thus many Isan people were avid supporters of the Red Shirts.
