The NSDAP Commemorative Long Service Medal is a noteworthy artifact that recognizes the dedication and loyalty of individuals within the NSDAP organization over a span of time. This prestigious award was bestowed upon members for distinguished service of 10, 15, and 25 years. Each medal features a distinctive design, characterized by a four-armed cross with gently curved arms, centrally adorned with the state eagle encircled by an oak wreath. The reverse side of the medal bears the inscription in German: Treue für Führer und Volk ("Loyalty to Führer and People"), symbolizing the commitment of the awardees to their party and its ideals.

• Issued in three levels for 10, 15, and 25 years of service
• Features a unique design with the state eagle and an oak wreath
• Represents a significant portion of Nazi Germany's history (1920-1945)
• Commenced on April 2, 1939, under Adolf Hitler's directive

This award holds historical relevance, as the duration served prior to the official recognition was often calculated differently, accounting for the Kampfzeit ("struggle period") between 1925 and 1933. This period allowed for increased recognition of contributions made during the formative years of the party. The awarding of this medal was calculated on a doubling basis during those years, ensuring that the commitment of party members was appropriately acknowledged.
