This article introduces the notion of Europe's ‘long 1989’. It does so in order to connect the remarkable events in Central and Eastern Europe in 1989 to a wider set of transformations that have reshaped Europe as a whole. The article focuses on three sets of transformation. Firstly, the dismantling of political systems forged in the earlier era of ideological polarisation. Secondly, the ‘modernisation’ of national economies that entailed the disappearance of the institutional expressions of class compromise after 1945 (in the Stalinist and social democratic forms). Thirdly, the unravelling of those collective identities – class, religion, gender and sexuality – that had come to shape individual experiences so forcefully across the twentieth century. The article explores the liberating effects of these transformations whilst arguing that the principle dynamic has been that of implosion. The resulting sense of loss has shaped contemporary Europe in multiple ways.
