The authoritarian right is taking control. From Viktor Orban in Hungary, to Brexit in Britain, to Donald Trump in America, nationalists are launching an all-out assault on liberal values. In this groundbreaking new book, political journalist Ian Dunt tells the story of liberalism, from its birth in the fight against absolute monarchy to the modern-day resistance against the new populism. In a soaring narrative that stretches from the battlefields of the English Civil War to the 2008 financial crash and beyond, this vivid, page-turning book explains the political ideas which underpin the modern world. But it is also something much more than that it is a rallying cry for those who still believe in freedom and reason.
