Symposium: Het Rampjaar 350: Origins and Aftermaths of 1672 in European and Global Perspectives

Date: Friday, 1st July 2022, and Saturday, 2nd July 2022

Overview: The invasion of the United Provinces by Louis XIV in 1672 (‘Het Rampjaar,’ ‘the year of disaster’ in Dutch memory) is a pivotal event in Dutch political and cultural history. However, its impact reverberated far beyond the Netherlands, shedding light on long-term global processes. This online symposium explores the broader dimensions of 1672, delving into its significance in arenas extending well beyond Dutch borders.

Call for Papers: We welcome proposals for 20-minute papers addressing themes such as geopolitics, confessional politics, state building, power dynamics, information dissemination, public participation in politics, imperial expansion, economics, trade patterns, commemoration, artistic representation, and identity. Contributions can analyze how the events of 1672 in the Netherlands influenced internal discussions or policies in other countries, compare the Dutch experience with events elsewhere, or examine how the Rampjaar illustrated broader European and global processes.
