When Hitler gained power in 1933, he appointed Frick as Reich Minister of the Interior.

On April 7th 1933, Frick enacted the ‘Law for the Restoration of the Civil Service’, which placed Nazis in all senior positions.

In 1935 Frick was given the authority to appoint mayors to cities and towns with a population of 100,000 or more other than Berlin and Hamburg.

Frick played a key part in the passage of the Nuremberg Laws and other anti-Semite legislation.
