All three steps are being taken around the world - not least with the election of Donald Trump - and we must all understand how we can stop them.In How Democracies Die, Harvard professors Steven Levitsky and Daniel Ziblatt draw insightful lessons from across history - from the rule of General Augusto Pinochet in Chile to the quiet undermining of Turkey's constitutional system by President Recip Erdogan - to shine a light on regime breakdown across the twentieth and twenty-first centuries. Notably they point to the dangers of an authoritarian leader faced with a major crisis. Based on years of research, they present a deep understanding of how and why democracies die; an alarming analysis of how democracy is being subverted today in the US and beyond; and a guide for maintaining and repairing a threatened democracy, for governments, political parties and individuals. History doesn't repeat itself. But we can protect our democracy by learning its lessons, before it's too late.
