This book explains why ethnic nationalists like Donald Trump in the US, Marine Le Pen in France, and the Brexit campaigners in the UK have gained so much support in the last few years. Through careful analysis of the social media campaigns of these new nationalists, Schertzer and Woods show how these leaders are tapping into the history and culture of white majorities. Their cutting-edge and multidisciplinary approach--combining elements of political science, sociology, history, and communication and media studies--highlights how leaders today are updating the historical foundations of ethnic identity for the digital age to win elections.
