**Anne Applebaum, Garry Kasparov, Richard North Patterson, and a constellation of other thinkers make the urgent case for liberal democracy — reinvigorating its central values in an age of doubt and discord.** Liberal democracy is in crisis around the world, besieged by authoritarianism, nationalism, and other illiberal forces. Far-right parties are gaining traction in Europe, Vladimir Putin tightens his grip on Russia and undermines democracy abroad, and America struggles with poisonous threats from the right and left. But the defenders of democracy are strong too. Taking their cues from the 1788 Federalist Papers, the Renew Democracy Initiative is a collective of pro-democracy advocates from across the political spectrum, including Anne Applebaum, Garry Kasparov, Max Boot, Bret Stephens, Ted Koppel, and Natan Sharansky. This book is their foundational document, a collection of essays that analyze the multi-pronged threats to liberal democracy in the U.S. and abroad, and offer solutions based on fundamental democratic principles such as freedom of speech, a free press, and the rule of law. *Fight for Liberty* is a roadmap for the struggle against the rising tide of extremism and a *cri de coeur* in defense of the liberal world order, which sees itself threatened as never before today.
