“Should the United Kingdom remain a member of the European Union?”
This is the question on which citizens of the United Kingdom will vote on June 23. Historians have actively participated in the debate during the lead up to the national plebiscite. A group of 42 calling themselves Historians for Britain have advocated leaving the European Union, while a much larger group of historians have signed a letter saying that leaving the EU will “condemn Britain to irrelevance.” Given the long interwoven fates of the countries that now make up the European Union, contributions by historians are vital to understanding the geopolitics of remaining or leaving.
