Policing the Nazi State
When people think of policing and intelligence within the Nazi state, people often narrow it down to the SS and the Gestapo. But there were other institutions and often we misunderstand the roles of the organisations that we know. This is for a number of reasons, often there was overlap between the groups, but also up until it was consolidated under Himmler, there were a lot of power struggles between the groups and those in charge of them.
The policing and security groups focussed mostly on fear, violence, and intimidation, which was maintained through a complex network of groups that operated at different levels of society. These groups were tasked with maintaining law and order, suppressing dissent, and enforcing Nazi ideology.
This is a brief overview of some of them. Please bear in mind this is very brief and that each group had aspects that will not be covered. If you have an interest in this please research this more from trusted resources.
