The name of Nazi Germany's official secret police was the Geheime Staatspolizei (Secret State Police), commonly known as the Gestapo. They were responsible for investigating and suppressing any opposition to the Nazi regime and enforcing their policies through fear, intimidation, torture, and murder. The Gestapo played a major role in the Holocaust, as they were responsible for the arrest and deportation of millions of Jews and other groups targeted by the Nazi regime.
