Brian Cowan, Faculty of Arts, McGill University

“The 2016 Brexit referendum has created a constitutional crisis that remains unresolved. What began as an internal problem for the UK's Conservative Party has now become a national problem that threatens the structures of Britain's democracy and the union of England/Wales, Scotland and Northern Ireland.” – Brian Cowan

Professor Cowan holds the Canada Research Chair in Early Modern British History. He studies the social and cultural history of ideas in early modern Britain and Europe.
