The memorial plaque for the Revolutionary Committee of the Budapest Municipal District Újpest was installed on the exterior wall of the Újpest Town Hall on October 23, 1989. The plaque was financed by donations from former participants of the rebellion and city inhabitants. One day following the first large-scale demonstration in the Budapest city centre – October 24, 1956 – thousands of people gathered before the Újpest Town Hall. During the morning of the same day, the first Workers' Council of the capital city had been formed at the neighbouring United Electricity Works (Egyesült Izzó), where a catalogue of demands had also been formulated in reaction to the most recent developments. Pál Kósa, a carpenter, read this catalogue aloud to the assembled demonstrators. During this rally, a Revolutionary Committee was spontaneously elected and Kósa was appointed as its chairman. This body assumed the administration of the municipal district, after having deposed the former municipal administration. Within this Committee – besides the demonstrators elected to various offices – were also representatives from the largest production operations and trade associations; simple workers constituted the majority. At the initiative of the Revolutionary Committee, an armed Civil Guard was established to enforce public security and maintain order. Several members of the Hungarian Secret Service, but also party functionaries and industrialists, were soon arrested and placed in detention. Due to these efforts, in contrast to what could often be observed in other municipal districts, Ùjpest did not become the scene of vigilante justice or other excesses. On October 26, 1956, the Revolutionary Committee ratified its own programme, which – along with plans to establish a new government with the participation of insurgents, the withdrawal of Soviet troops and the neutrality of the Hungarian state – also contained provisions for the organisation of a national strike until these demands had been met. After the renewed invasion of Soviet armed forces on November 4, 1956, the Revolutionary Committee succeeded in establishing contact with the military command of the invading forces. After negotiations, it was at first possible to halt the advance of Soviet troops into Újpest. The Revolutionary Committee and Civil Guard retained control of the municipal district, and were not forced to oppose the Soviet forces with military means. This truce lasted until November 8th, after which Újpest was also occupied in the wake of violent battles. Nonetheless, the Revolutionary Committee officially existed until November 12, 1956 and went on to hold negotiations with the formerly deposed but re-established state administration concerning the reinforcement of public order. In the morning of the following day, however, the members were arrested by Soviet troops. The Workers' Councils which had been established in the production centres continued to exist until December 1956, until they, too, were forced to dissolve under the pressures of the new government. In mid-1958, the leaders of the Revolutionary Committee of Újpest were finally condemned and sentenced. Pál Kósa and six other individuals were sentenced to death and executed, while more than twenty others received long prison sentences.
