We live in an increasingly nationalistic age, with globalisation stumbling and international institutions disregarded. But we have been here before.
Nations have existed for centuries, but it's only in the last 200 years that nationalism has become such a huge influence.
So, where does nationalism come from? How has it changed since its inception? And what can its history tell us about its future?
Join Nick Spencer as he speaks to Eric Storm, Senior Lecturer in European History at Leiden University and author of 'Nationalism: a world history', a global perspective on the nature and evolution of nationalism, from the early modern era to the present.
