Investigations Police of Chile

History.
19th century.
The first reference to police work in Chile is in the Police Regulation of 1803, where the terms "high police" and "public security" are used. Then, in 1830, the "Vigilantes" and "Serenos Corps" of Santiago were created, whose work was followed throughout the country. In 1852 the "Brigada de Policía" was created in Santiago, where the "Vigilantes" and "Serenos Corps" were merged.
In the 1870s , the mayor of the city of Santiago, Benjamín Vicuña Mackenna proposed modelling the "Brigada de Policía" on the "Agent de la Sûrete" in Paris, France, which was based on the administrative structure of the police force. Ranks of "Inspector", "Comisario", and "Prefecto" (based on the French ranks of "Inspecteur", "Commissaire", and "Préfet") were implemented, and that are still used today. 
20th century.
The modern Investigations Police was established in 1933 as a separate organization of civil police, independent from the control of the militarized Carabineros de Chile.
