In my work, I have examined the works of two local historians of Érsekújvár (Slovak: Nové Zámky), Gyula Vágovits and Kázmér Saskó. In addition to presenting the local historians and their works, I examined three local events related to the change of sovereignty between 1918 and 1920.  These were the organisation of resistance in Érsekújvár, the occupation of the town and the toppling of the Kossuth statue. I examined not only the way the two authors present these events, but also the extent to which their interpretations correspond to reality, i.e. to what extent their interpretations could be considered plausible on the basis of archival sources. My work will also show how and why the narratives of the works differ, and will correct some local events that have been misinterpreted.
