From Brexit Britain to Donald Trump's America, nationalists are launching an all-out assault on liberal values. In this groundbreaking new book, 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.
