Large-scale killings and civil unrest primarily targeting members of the Communist Party (PKI) were carried out in Indonesia from 1965 to 1966. Other affected groups included alleged communist sympathisers, Gerwani women, ethnic Javanese Abangan,[1] ethnic Chinese, atheists, so-called "unbelievers", and alleged leftists in general.
It is estimated that between 500,000 and 1,000,000 people were killed during the main period of violence from October 1965 to March 1966.
