The Romani Holocaust was the genocide of European Roma and Sinti people during World War II. Beginning in 1933, Nazi Germany systematically persecuted the European Roma, Sinti and other peoples pejoratively labeled "Gypsy" through forcible internment and compulsory sterilization. German authorities summarily and arbitrarily subjected Romani people to incarceration, forced labor, deportation and mass murder in concentration and extermination camps.
