After threats to the security of the Warsaw pact, and the Soviet Union's buffer zone, tanks rolled into the Hungarian capital: Budapest on 4 November 1956.
Supporters of Nagy put up a fight and begged the West for support (no support came). It is estimated 20,000 Hungarians were killed as Soviet forces re-established control. Again, a new communist party was set up, this time under Janos Kadar and Nagy was executed.
