The Geheime Staatspolizei (German for "secret state police"), commonly abbreviated as Gestapo, formed the official state secret police force of Nazi Germany.
The Gestapo had the authority to investigate all suspected acts of treason, sabotage, espionage, and criminal attacks against the Nazi Party.

The Gestapo was an organization of over 40,000 agents who each controlled a network of spies and informant. The Gestapo was responsible for rounding up communists, Jews, and other people thought to be a threat to the German government.
