The Chinese Communist Party allows no public commemoration of the protest movement that it violently crushed in the vicinity of Tiananmen Square in 1989, but its private reckoning with that tragedy has never mattered more. President Xi Jinping has quietly taken Tiananmen as a guiding light, reading it as a cautionary tale of regime decay and a playbook for revival. This view has inspired his campaigns to tackle corruption, restore ideological discipline, and reclaim control over history. And the most lasting contribution of all to Xi's tenure may be the selective rehabilitation of traditional Chinese culture as a source of political legitimacy.
