Where does the data come from?

The NaziCrimesAtlas is based on various sources, including public registers and the academic work of Dr. Edith Raim. She has dealt intensively with the Nazi crimes prosecuted after 1945 and published extensive works. published since 2014 and has continued to research and investigate since then. Further sources are available online, such as the website “Justice and Nazi Crimes” or archives such as the Central Office Ludwigsburg, Yad Vashem and others. One focus is on the crimes that were prosecuted after 1945 and recorded in court files. There are around 25,000 files in East and West Germany. In addition, there are further sources of cases that were not legally prosecuted but are recorded or documented in sources. With the help of these sources, the events of the time can be further researched and the facts used for further projects on the history of the Nazi dictatorship. Further crime scenes are made accessible through other sources, through lists of concentration camps, torture cellars and also everyday sites of Nazi crimes.

Are the original sources available in the app?

No, the application always shows the crime scene with the geographical data of the crime. If possible, the time period. Depending on the crime, there is also a brief description and where sources can be found. However, no personal data is published.

What can I find out with the app?

The app displays the crime scenes geo-referenced:

  • A brief description of the crime
  • Period
  • Source

Optional are possible:

  • Detailed description of the crime
  • Project on the culture of remembrance at the site
  • Audio or video
  • Press links
  • Panorama tours
  • Information on stumbling blocks, memorials, monuments, memorial sites …
  • Further links

Is the app the only digital storage for this data?

We are aware that smartphone apps are not an ideal digital repository of knowledge. Our app serves as an entry point and research tool in the context of public history.

Why are function titles such as “local group leader”, “mayor”, but no names mentioned?

The Data protection requirements and Archives complicate it, the Names the Perpetrator to call, the often better protected are as the Victim.
It is about the 25.000 files are also about even more from victims and perpetrators. We are unable to clarify the rights and data protection of naming names in individual cases.
Therefore is it legally compliant, the Names first not to call.
We hope however, that local Initiatives these short Summaries more research and Article in addition compose, the we in the App integrate can. So leaves itself the Name of the earlier Mayor, Gestapo– or local group leader and also name them.

Why are the images blurred?

We do not yet have images for the more than 3000 entries in this digital map Pogroms. We have therefore used placeholder images that only show a blurred background.
We hope that we will learn more about these events and Nazi crimes through the cooperation of many local actors and, in the best case, also obtain visual material.

Who can help me with further research?

We offer training and further education in 2025. We teach how to handle historical sources correctly, how to find further facts about a subject in archives, who to contact locally or in the region you are researching.

Are all deeds recorded in the app?

We are currently working on thousands of Nazi crimes in the territory of today’s Federal Republic of Germany, which we are dividing into various categories and subject areas. The first topics we will make available are the crimes of the pogroms of 1938, the murder of the sick and the crimes in the concentration camps and subcamps. We will then work on the other categories, such as torture cellars or Nazi crimes in places of everyday life, as is often the case with denunciations.
