What was the Holocaust?
The Holocaust was the systematic, state-sponsored persecution and murder of six million European Jews by Nazi Germany, its allies, and its collaborators between 1933 and 1945.
Millions of others were persecuted and killed under Nazi rule. The genocide developed in stages, through exclusion, propaganda, theft, forced displacement, ghettos, mass shootings, deportation, forced labor, and purpose-built killing centers.
Holocaust memory is central to SWC's mission
SWC preserves this history through archives, museums, educational programs, and storytelling. A documented record is the strongest protection memory has.
The audience keeps changing. Each generation meets this history for the first time, so reference material must also serve people who arrive with little prior knowledge.
A chronology in five stages
Treating the period as one event hides how it developed. Each stage made the next easier, and ordinary institutions carried out much of the administrative work.
- Exclusion by law
- Organized violence
- Ghettos and mass shooting
- Deportation and killing centers
- Death marches and liberation

Exclusion came before killing
The first years were legal and bureaucratic. The regime stripped citizenship, closed professions, seized property, and criminalized social contact through published statutes administered by civil servants.
By the time deportations began, the targeted population had already been isolated, impoverished, and registered. That administrative groundwork made the later stages possible on such a large scale.
Evidence that documents the genocide
The record is unusually large because the perpetrators were bureaucrats who wrote things down, and because survivors, liberators, and courts assembled material for decades afterward.
- German state records
- Ghetto and camp documentation
- Survivor testimony
- Perpetrator statements
- Physical sites and forensics
Who was targeted and on what terms
Jews were targeted for total annihilation across every territory the regime reached, which is what defines the Holocaust specifically. Roma and Sinti were also subjected to genocidal policy.
Disabled people, Soviet prisoners of war, Polish civilians, political opponents, Jehovah's Witnesses, and gay men were persecuted and murdered under distinct programs with distinct logics.
Where the figures come from
The six million estimate draws on prewar and postwar census data, deportation and transport records, and the reconstruction of destroyed Jewish communities across Europe after the war.
Some regions have ranges because records were destroyed or never created. That is normal historical practice and does not put the overall scale in question.
Where to begin studying it
Institutional collections are the best starting point because they provide provenance, dates, and curation that an isolated document or image cannot supply on its own.
- National memorial museums
- Testimony archives
- Digitized document collections
- Trial transcripts
- Curated survivor accounts
Why reference material still changes
Archives continue to open, and researchers are still surveying camps and shooting sites while refining regional death tolls with newly available records and local documentation.
That kind of revision is normal historical work. It refines detail within the established record rather than arguing against the event itself or its scale.
Common Questions
- How many Jews were murdered?
- Approximately six million. That estimate draws on census data, deportation and transport records, and the reconstruction of destroyed communities across many countries.
- Were Jews the only victims?
- No. Roma and Sinti also faced genocidal policy, and many other groups were persecuted and murdered under separate programs. Jews were targeted for total annihilation.
- Where should a student begin?
- With institutional collections at memorial museums and testimony archives, where documents carry provenance and dating that isolated images and excerpts lack.
- Why do regional figures sometimes differ?
- Because records were destroyed or never created in some areas. Ranges reflect the available evidence and do not affect the established overall scale.
- Is new evidence still emerging?
- Yes. Archives continue to open and sites are still being surveyed, refining regional detail within the established record rather than overturning it.
