In a powerful new book, the journalist and historian reveals how her former friends and colleagues became agents of populism

Anne Applebaum can look at the wreck of democratic politics and understand it with a completeness few contemporary writers can match. When she asks who sent Britain into the unending Brexit crisis, or inflicted the Trump administration on America, or turned Poland and Hungary into one-party states, she does not need to search press cuttings. Her friends did it, she replies. Or, rather, her former friends. For if they are now embarrassed to have once known her, the feeling is reciprocated.

Applebaum’s latest book, Twilight of Democracy: The Failure of Politics and the Parting of Friends, opens with a scene a novelist could steal. On 31 December 1999, Applebaum and her husband, Radosław Sikorski, a minister in Poland’s then centre-right government, threw a party. It was a Millennium Eve housewarming for a manor house in the western Poland they had helped rebuild from ruins. The company of Poles, Brits, Americans and Russians could say that they had rebuilt a ruined world. Unlike the bulk of the left of the age, they had stood up against the Soviet empire and played a part in the fall of a cruel and suffocating tyranny. They had supported free markets, free elections, the rule of law and democracies sticking together in the EU and Nato, because these causes – surely – were the best ways for nations to help their people lead better lives as they faced Russian and Chinese power, Islamism and climate change.
