How did the Gestapo help the Nazis control Germany?

The Gestapo served as the primary instrument of terror for the Nazi regime, operating without civil restraints to ruthlessly eliminate any perceived opposition. By functioning outside the bounds of judicial oversight, the Gestapo held the authority of "preventive arrest," allowing them to imprison thousands of intellectuals, political clergy, trade unionists, and others in concentration camps without the possibility of appeal.1

To maintain control, the Gestapo relied heavily on denunciations from the local populace to conduct investigations, as their own staff remained relatively small. Under the leadership of Heinrich Himmler and Reinhard Heydrich, the organization was integrated into the Reichssicherheitshauptamt, where it coordinated with other security departments to suppress dissent. Beyond domestic control, the Gestapo played a central role in the Holocaust, managing the persecution of "inferior races" and organizing the deportation of millions of Jews to extermination camps. The use of such brutal, extrajudicial power was a fundamental violation of human rights and a core pillar of the Nazi dictatorship.1
