Aftermath of the Hungarian Uprising in Hungary

From the Wikipedia page [1]

In the immediate aftermath, many thousands of Hungarians were arrested. Eventually, 26,000 of these were brought before the Hungarian courts, 22,000 were sentenced and imprisoned, 13,000 interned, and 229 executed. Hundreds were also deported to the Soviet Union, many without evidence. Former Hungarian Foreign Minister Géza Jeszenszky estimated 350 were executed. Sporadic resistance and strikes by [ workers' council]s continued until mid-1957, causing economic disruption. Despite the devastation of the Soviet attack, most of Hungarian society seemed to respond to Bibó's plea and continued to defy the new regime, keeping Soviet and Hungarian security forces tied up for months dealing with strikes, demonstrations, sabotage, work slowdowns, and other acts of resistance. By 1963, most political prisoners from the 1956 Hungarian revolution had been released.

With most of Budapest under Soviet control by 8 November, János Kádár became Prime Minister of the "Revolutionary Worker-Peasant Government" and General Secretary of the Hungarian Communist Party. Few Hungarians rejoined the reorganised Party, its leadership having been purged under the supervision of the Soviet Praesidium, led by Georgy Malenkov and Mikhail Suslov. Although Party membership declined from 800,000 before the uprising to 100,000 by December 1956, Kádár steadily increased his control over Hungary and neutralised dissenters. The new government attempted to enlist support by espousing popular principles of Hungarian self-determination voiced during the uprising, but Soviet troops remained. After 1956 the Soviet Union severely purged the Hungarian Army and reinstituted political indoctrination in the units that remained. In May 1957, the Soviet Union increased its troop levels in Hungary and by treaty Hungary accepted the Soviet presence on a permanent basis.

The Red Cross and the Austrian Army established refugee camps in the Traiskirchen/ Baden (district of Austria and Graz. Imre Nagy along with Georg Lukács, Géza Losonczy, and László Rajk's widow, Júlia, took refuge in the Embassy of Yugoslavia as Soviet forces overran Budapest. Despite assurances of safe passage out of Hungary by the Soviets and the Kádár government, Nagy and his group were arrested when attempting to leave the embassy on 22 November and taken to Romania. Losonczy died while on a hunger strike in prison awaiting trial when his jailers "carelessly pushed a feeding tube down his windpipe.

The remainder of the group was returned to Budapest in 1958. Nagy was executed, along with Pál Maléter and Miklós Gimes, after secret trials in June 1958. Their bodies were placed in unmarked graves in the Municipal Cemetery outside Budapest.

During the November 1956 Soviet assault on Budapest, Cardinal Mindszenty was granted political asylum at the United States embassy, where he lived for the next 15 years, refusing to leave Hungary unless the government reversed his 1949 conviction for treason. Because of poor health and a request from the Vatican, he finally left the embassy for Austria in September 1971.
