How did the Gestapo become a tool of Nazi rule?

The Gestapo became a primary instrument of Nazi rule by operating as a political police force that functioned without civil restraints or judicial oversight. Its transformation into a tool of state terror occurred through several key developments:1

• Institutional Control: In 1933, Hermann Göring established the Gestapo by detaching political and espionage units from the regular Prussian police and filling their ranks with Nazis. By 1936, Heinrich Himmler unified all German police forces under his command, integrating the Gestapo into a broader security apparatus that included the SS and the Sicherheitsdienst.12
• Elimination of Opposition: The Gestapo ruthlessly targeted perceived enemies of the state, including intellectuals, trade unionists, political clergy, and marginalized groups. It held the authority of "preventive arrest," allowing it to imprison individuals in concentration camps without legal appeal.1
• Reliance on Denunciation: Due to its relatively small size, the Gestapo maintained control by encouraging the local populace to report on one another, effectively turning citizens into informants for the regime.1

Through these methods, the Gestapo enforced the Nazi Party's absolute authority, suppressing dissent and facilitating the atrocities of the Holocaust.1
