Rákosi—who in 1952 came to preside over the government as well as the party—was, under Moscow’s direction, all-powerful until the death of Stalin in 1953, when a period of fluctuation began. In July 1953 Rákosi was deposed from the prime ministership in favour of Imre Nagy—a “Muscovite” but a Hungarian in his attitudes and not unpopular in the country. Nagy promised a new course—an end to the forced development of heavy industry, more consumer goods, no more forcing of peasants into the collectives, the release of political prisoners, and the closing of internment camps. He introduced some of these reforms, but Moscow hesitated to support him. In the spring of 1955, Nagy was dismissed from office and expelled from the party.

Rákosi was reinstated, and he put the country back on its previous course. He was dismissed again in July 1956, this time from all his offices and in disgrace. The new Soviet leader, Nikita S. Khrushchev, had sacrificed Rákosi as a gesture to the Yugoslavian leader Josip Broz Tito, whom Rákosi had offended personally and whom the Soviet leadership wished to placate. The new leader, Ernő Gerő, Rákosi’s deputy, was almost as detested as Rákosi himself. Gerő promptly announced that there would be no concessions on matters of principle to Nagy and his group.

The relaxation of pressure under Nagy (though transitory), Khrushchev’s “secret speech” denouncing Stalin’s cult of personality—delivered at the 20th Congress of the Communist Party of the Soviet Union in February 1956—and the Polish challenge to the Soviet Union in the spring and summer of 1956 emboldened Hungarians. On October 23, students in Budapest staged a great procession, which was to end with the presentation of a petition asking for redress of the nation’s grievances. People flocked into the streets to join them. Gerő answered with an unwise and truculent speech, and police fired into the crowds. The shots turned a peaceful demonstration into a revolutionary one. The army joined the revolutionaries, and army depots and munitions factories handed out arms. Outside Budapest, local councils sprang up in every centre. The peasants reoccupied their confiscated fields. The communist bureaucracy melted away. Prison doors were opened. The members of the State Security Authority fled if they could. A cheering crowd escorted Cardinal Mindszenty back to the primate’s palace.

In kaleidoscopic political changes, Nagy resumed power on October 25 but then was driven from one concession to the next. On November 3 he found himself at the head of a new and genuine coalition government representing the reconstituted Hungarian Socialist Workers’ Party and the revived Smallholders’ Party, Social Democratic Party, and Petőfi [former National Peasant] Party.

The Soviet troops had withdrawn, and Nagy was negotiating for their complete evacuation from Hungary. On November 1 he announced Hungary’s withdrawal from the Warsaw Pact (to which it had adhered since 1955) and asked the United Nations to recognize his country as a neutral state, under the joint protection of the great powers. Soviet officials were uncertain whether to act or to let matters take their course, for fear of Western intervention. But the growing pressures for intervention from China and neighbouring Romania, Czechoslovakia, and eventually even Yugoslavia; the danger posed by Nagy’s gravitation out of the Soviet bloc; Israeli, British, and French involvement in the Suez Crisis; and an increasing realization that the United States would not risk a global confrontation over Hungary emboldened the Soviet leadership to act. Their tanks, which had halted just across the frontier, began to return, reinforced by other units. On November 4 the Soviet forces entered Budapest and began liquidating the revolution. Nagy took refuge in the Yugoslav embassy and Cardinal Mindszenty in the U.S. legation. Gen. Pál Maléter, the Nagy government’s minister of defense, who had been invited by the Soviet commanders to negotiate, was taken captive and eventually executed.

In the early morning of the same day, János Kádár—who had defected from the Nagy government and left Budapest on November 1—broadcast a radio speech wherein he declared the illegitimacy of the Nagy government and proclaimed the formation of the new Soviet-supported “Hungarian revolutionary workers’ and peasants’ government.” It consisted entirely of communists, who now congregated under the flag of the Hungarian Socialist Workers’ Party that had replaced the discredited Hungarian Workers’ Party. The new government was headed by Kádár as prime minister and Ferenc Münnich as his second in command. Kádár promised that once the “counterrevolution” was suppressed and order was restored, he would negotiate for the withdrawal of the Soviet garrison (although the denunciation of the Warsaw Pact was retracted). Having been imprisoned himself by Rákosi’s Stalinist regime, he now dissociated himself from the “Rákosi-Gerő clique” and promised substantial internal reforms.

Most Hungarians, however, were skeptical of these promises, and fighting continued. But the odds were too heavy in favour of the Soviets, and the major hostilities were over within a fortnight, although sporadic encounters continued into January 1957. The workers continued their struggle by proclaiming a general strike and other forms of peaceful resistance. It took many weeks before they were brought to heel and many more months before some semblance of normality returned to the country. The price in human lives was great. According to the calculations of historians, the Hungarians suffered about 20,000 casualties, among them some 2,500 deaths, while the Soviet losses consisted of about 1,250 wounded and more than 650 dead.

Meanwhile, Nagy, who had left his place of refuge under safe conduct, had been abducted and taken to Romania. After a secret trial, he and Maléter and a few close associates were executed in 1958. Many lesser figures were seized and transported to the Soviet Union, some never to return, and 200,000 refugees escaped to the West (about 38,000 of whom emigrated to North America in 1956–57). Thus, a substantial proportion of Hungary’s young and educated classes was lost to the country, including several top noncommunist political leaders and intellectuals, as well as Gen. Béla K. Király, the commander of the Hungarian National Guard organized during the revolution. Material damage was also very heavy, especially in Budapest.
