Introduction by Alexander Odinius

The Secret Prussian State Archives in Berlin (Geheimes Staatsarchiv Preußischer Kulturbesitz) house the files on individuals who applied for naturalization. These included immigrants as well as individuals who had already lived in Germany for an extended period and had lost their citizenship. They were stateless.

Before the founding of the German Empire in 1871, German states such as the Kingdoms of Saxony and Bavaria processed their naturalization applications based on their own laws and regulations. Bavaria and Prussia created the first legal regulations and defined citizenship for their respective jurisdictions. On June 1, 1870, the Reichstag of the North German Confederation passed the "Federal Law on the Acquisition and Loss of Federal and State Citizenship," which was extended to all of Germany upon the founding of the German Empire in 1871. The law was subsequently replaced by the "Reichs Citizenship and Nationality Act" (RuStAG), which came into force on January 1, 1914. Subsequently, the individual federal states (Saxony, Prussia, Bavaria, etc.) processed applications for naturalization from applicants residing in their jurisdiction, but in doing so, they were guided by the RustAG.

Due in particular to pogroms in Russia, the number of Jewish refugees seeking refuge in Western Europe increased significantly. This initially affected the Austrian province of Galicia, located on the border with Russia, but also Germany. After World War I, the number of naturalization applications increased significantly due to the territorial cessions agreed upon in the Treaty of Versailles. After the Nazis seized power in 1933, the naturalization laws were abolished.

The data published here concern applicants of Jewish faith or converts who applied for naturalization in Prussia. Due to the war, the remaining files are no longer complete. The database contains only individuals who can be identified based on the documents still available. In total, this includes over 4,700 individuals. Since the applications generally included all family members, the actual number of individuals registered is far higher, more than 10,000 individuals.
