In 1956, the construction was hindered by an earthquake and a flood, and in October by the start of the 1956 Hungarian Revolution. During the revolution the city used its historical name "Dunapentele" again. The "Rákóczi" radio station, which was created by the revolutionaries, broadcast from Dunapentele (in fact from a bus that was constantly moving around in the city so that it couldn't be located.) Even though the citizens of Dunapentele tried to defend their city, the Soviet army occupied the city on November 7, 1956. The city came under martial law and soviet tanks were stationed throughout the city.
