The Romani genocide or the Romani Holocaust—also known as the Porajmos (Romani pronunciation: IPA: [pʰoɽajˈmos]), the Pharrajimos ("Cutting up", "Fragmentation", "Destruction"), and the Samudaripen ("Mass killing")—was the effort by Nazi Germany and its World War II allies to commit genocide against Europe's Romani people.
Under Adolf Hitler, a supplementary decree to the Nuremberg Laws was issued on 26 November 1935, classifying Gypsies as "enemies of the race-based state", thereby placing them in the same category as the Jews. Thus, in some ways the fate of the Roma in Europe paralleled that of the Jews in the Jewish Holocaust.
Historians estimate that between 220,000 and 500,000 Romani were killed by the Nazis and their collaborators—25% to over 50% of the slightly fewer than 1 million Roma in Europe at the time.Ian Hancock puts the death toll as high as 1.5 million.
In 1982 West Germany formally recognized that Nazi Germany had committed genocide against the Romani. In 2011 Poland officially adopted 2 August as a day of commemoration of the Romani genocide.
The term porajmos (also porrajmos or pharrajimos—literally, "devouring" or "destruction" in some dialects of the Romani language) was introduced by Ian Hancock, in the early 1990s. Hancock chose the term, coined by a Kalderash Rom, from a number of suggestions in an "informal conversation in 1993".
The term is used mostly by activists and is unknown to most Roma, including relatives of victims and survivors. Some Russian and Balkan Romani activists protest against using the word porajmos. In various dialects, porajmos is synonymous with poravipe which means "violation" and "rape", a term which some Roma consider to be offensive. János Bársony and Ágnes Daróczi, pioneering organisers of the Romani civil rights movement in Hungary, prefer the Pharrajimos, a Romani word meaning "cutting up", "fragmentation", "destruction". They argue against using porrajmos, saying it is marhime (unclean, untouchable): "[p]orrajmos is unpronounceable in the Roma community, and thus is incapable of conveying the sufferings of the Roma".
