Interpol

The International Criminal Police Organization – INTERPOL, commonly known as Interpol, is an international organization that facilitates worldwide police cooperation and crime control. It is the world's largest international police organization. It is headquartered in Lyon, France, with seven regional bureaus worldwide, and a National Central Bureau in all 196 member states.

The organization today known as Interpol was founded on 7 September 1923 at the close of a five-day International Police Congress in Vienna as the International Criminal Police Commission; it adopted many of its current duties throughout the 1930s. After coming under Nazi control in 1938, the agency had its headquarters in the same building as the Gestapo. It was effectively stagnant until the end of World War II. In 1956, the ICPC adopted a new constitution and the name Interpol, derived from its telegraphic address used since 1946.
