Parti des travailleurs hongrois
During the night of 23 October, Hungarian Working People's Party Secretary Ernő Gerő requested Soviet military intervention "to suppress a demonstration that was reaching an ever greater and unprecedented scale". The Soviet leadership had formulated contingency plans for intervention in Hungary several months earlier. By 02:00 on 24 October, acting in accordance with orders of Georgy Zhukov, the Soviet defence minister, Soviet tanks entered Budapest.
