Printed Pandemonium is a fresh take on one of the most violent political upheavals in early modern history: the popular riots, the political murders and the brutal purifications of local governments in the Dutch Republic during the so-called ‘Year of Disaster’ 1672. Printed Pandemonium gives an insight into the relationship between political event and political communication in the early modern world. The popular revolts of 1672 were the work of ‘normal’ citizens who rioted and killed, but also politically participated by reading, writing and debating hundreds of different pamphlets and petitions that were put on the market during that momentous year. In total somewhere between one and two million pamphlets flooded the Dutch Republic in 1672. This study is the first analysis of all these pamphlets.
