A new searchable database has made millions of membership cards from the Nationalsozialistische Deutsche Arbeiterpartei (NSDAP) accessible to the public [2].

The project allows historians and families to trace the early administrative structure of the Nazi Party. By digitizing these records, researchers can better understand the growth and organization of the movement during its formative years.

A documentary segment released by Der Spiegel focuses on the period between 1925 and 1928 [1]. The material said that the NSDAP was founded twice, noting its origins as the Deutsche Arbeiterpartei (DAP) in 1920 [1]. This organizational history provides a framework for understanding how the party consolidated power before its eventual rise to total control in Germany.

Among the specific details highlighted in the records is the membership of Adolf Hitler. The documentation said Hitler held membership number 555 [1]. Such granular data helps scholars map the early hierarchy and the sequence of recruitment within the party's ranks.

The launch of the database coincides with the 81st anniversary of liberation from Nazi rule [2]. By converting millions of physical cards into a digital format, the project aims to remove barriers to historical inquiry [2]. The effort is a collaboration involving major German media outlets, including Der Spiegel and Zeit, to ensure the data remains a public resource.

Researchers can now use the tool to verify individual affiliations and study the demographics of party membership across different regions of Germany. The digitization process addresses the fragility of original paper records, ensuring that the evidence of the regime's early expansion is preserved for future generations.

“The NSDAP was founded twice, first in 1920 as the DAP.”

The digitization of these records transforms a massive physical archive into a queryable data set. This shift allows for quantitative analysis of the NSDAP's early growth patterns and individual accountability, providing a transparent digital ledger of those who formally joined the party during its ascent.
