The Roma (Gypsies) are thought to be one of the most affected groups in the holocaust. This is because about 250,000 Roma were killed during the holocaust by German military units, SS-police, and concentration camps such as Auschwitz where almost 19,000 out of the 23,000 Roma deported there died. This took place about 1940 when the Roma were deemed "Racially inferior" and thought to, as a character of the race, be asocial. Many were deported being sent to labor camps and ghettos. One example of these deportations was in 1940 where about 2,500 Roma were deported from the Greater German Reich to Poland where they were forced to work in conditions that killed many of them.
