Communist insurgency in Thailand
The communist insurgency in Thailand was a guerrilla war lasting from 1965 until 1983, fought mainly between the Communist Party of Thailand (CPT) and the government of Thailand. The war began to wind down in 1980 following the declaration of an amnesty, and in 1983, the CPT abandoned the insurgency entirely, ending the conflict.
