In light of the gross misuse of power by the centralized Nazi state, the new West German constitution provided a strict separation of powers, placing law enforcement firmly in the hands of the states. The only policing agencies allowed at the federal level were the paramilitary Federal Border Guard (German: Bundesgrenzschutz), also responsible for coast guard services and the Federal Criminal Police, both under the supervision of the Federal Ministry of the Interior. Because Germany's borders became largely open since 2005, due to the development of the European Union and the Schengen Agreement to all neighbourhood countries, the Bundesgrenzschutz was renamed to Federal Police (German: Bundespolizei).
