Autogenocide
Autogenocide is the arbitrary or ideologically inspired mass murder of a country's citizens by its own ethnic group against its own ethnic group. Auto comes from the Greek reflexive pronoun while genocide comes from Greek genos meaning "race, tribe" and the Latin word -cidere meaning "kill".
The term was coined in the latter half of the 1970s to describe the actions of the Khmer Rouge government of Cambodia, to distinguish such acts from the genocide of groups considered "other" by a government, such as the killing of Jews and people of Slavic origin by Nazi Germany. According to Samuel Totten 25% of the Urban Khmer population perished under the Khmer Rouge or 500,000 people, while rural Khmers lost 16% of their population or 825,000 putting the killing at a scale comparable to genocide of Roma and the genocide of Serbians during the Holocaust drawing the comparison to genocide aforementioned.
