The State Protection Authority (Hungarian: Államvédelmi Hatóság, ÁVH) was the secret police of the People's Republic of Hungary from 1945 to 1956. The ÁVH was conceived as an external appendage of the Soviet Union's KGB in Hungary responsible for supporting the ruling Hungarian Working People's Party and persecuting political criminals.
