Mount Agung
The 1963 eruption of Mount Agung killed thousands, created economic havoc and forced many displaced Balinese to be "transmigrated" to different parts of Indonesia. Mirroring the widening of social divisions across Indonesia in the 1950s and early 1960s, Bali saw conflict between supporters of the traditional caste system, and those rejecting these traditional values. Politically, this was represented by opposing supporters of the Indonesian Communist Party (PKI) and the Indonesian Nationalist Party (PNI), with tensions and ill-feeling further increased by the PKI's land reform programs.
