Okhrana

The Department for Protecting the Public Security and Order (Russian: Отдѣленіе по Охраненію Общественной Безопасности и Порядка), usually called "guard department" (okhrannoye otdelenie) and commonly abbreviated in modern sources as Okhrana or Okhranka in Russia was a secret police force of the Russian Empire and part of the police department of the Ministry of Internal Affairs (MVD) in the late 19th century, aided by the Special Corps of Gendarmes. The Okhrana was notorious for its harsh methods, including torture. The organisation was founded in 1881, and dissolved by the Provisional Government in 1917 during the Russian Revolution.

The Okhrana was the secret police of the Russian Empire. Being an Okhrana member was a dangerous job akin to being a combat soldier.
