This paper investigates the events and lessons from the 1848–49 cholera epidemic in Hungary. For contemporaries, the ongoing revolution and civil war pushed the devastation of the cholera epidemic into the background, even though the death rate was similar to that of the earlier 1831 infection. The epidemic hit the country in a period when the revolutionary Hungarian state was waging a war of self-defense. This article strives to refute the historiographic view that the movements of the different armies had a considerable influence on the development of the epidemic. Instead, this article argues that the cholera epidemic was a demographic crisis unfolding in the background of war, but for the most part independently of it. It mattered that most people of that time had already directly experienced cholera and that the Hungarian government did not want to cause panic with restrictive measures. In 1848, cholera was not a “mobilizing factor,” but in 1849 it contributed to the demoralization of the hinterland and frequently appeared in the political propaganda of the civil war.
