SD (Sicherheitsdienst)

The Sicherheitsdienst (SD) was the intelligence agency of the Nazi Party in Germany from 1931 to 1945. It was responsible for gathering information on political opponents, enemies, and other groups considered a threat to the Nazi regime. The SD played a key role in surveillance, espionage, and maintaining party control, often engaging in activities that facilitated repression, persecution, and violence. Its operations contributed to the oppressive atmosphere of Nazi Germany and the execution of numerous atrocities. Essentially, the SD functioned as a secret police and intelligence organization committed to safeguarding and advancing Nazi objectives.
