The current rise of nationalism across the globe is a reminder that we are not, after all, living in a borderless world of virtual connectivity. In Nationalism, historian Eric Storm sheds light on contemporary nationalist movements by exploring the global evolution of nationalism, beginning with the rise of the nation-state in the eighteenth century through the revival of nationalist ideas in the present day. Storm traces the emergence of the unitary nation-state which brought citizenship rights to some while excluding a multitude of 'others' and the pervasive spread of nationalist ideas through politics and culture.

Storm shows how nationalism influences the arts and humanities, mapping its dissemination through newspapers, television, and social media. Sports and tourism, too, have helped fashion a world of discrete nations, each with its own character, heroes, and highlights. Nationalism saturates the physical environment, not only in the form of national museums and patriotic statues but also in efforts to preserve cultural heritage, create national parks, invent ethnic dishes and beverages, promote traditional building practices, and cultivate native plants. Nationalism has even been used for selling cars, furniture, and fashion.

By tracing these tendencies across countries, Storm shows that nationalism's watershed moments were global. He argues that the rise of new nation-states was largely determined by shifts in the international context, that the relationships between nation-states and their citizens largely developed according to global patterns, and that worldwide intellectual trends influenced the nationalisation of both culture and environment. Over the centuries, nationalism has transformed both geopolitics and the everyday life of ordinary people.
