As part of its race-centric functions during World War II, the SS oversaw the isolation and displacement of Jews from the populations of the conquered territories, seizing their assets and deporting them to concentration camps and ghettos, where they were used as slave labor or immediately killed.[34] Chosen to implement the Final Solution ordered by Hitler, the SS were the main group responsible for the institutional killing and democide of more than 20 million people during the Holocaust, including approximately 5.2 million[49] to 6 million[2] Jews and 10.5 million Slavs.[49] A significant number of victims were members of other racial or ethnic groups such as the 258,000 Romani.[49] The SS was involved in killing people viewed as threats to race hygiene or Nazi ideology, including the mentally or physically handicapped, homosexuals, and political dissidents.
