Once a powerful political force across Europe, the Left is now facing one of its greatest challenges: survival. In an age marked by huge economic shifts, rising populism and the erosion of traditional working-class strongholds, the Left in Europe is in decline and even in a serious, possibly terminal crisis. This collection of essays critically examines the causes behind the downfall of socialist and social-democratic parties across the continent. Through an exploration of key moments in history, from the 1980s with the fall of the Berlin Wall to the rise of "neoliberalism" and globalization, the authors reveal how the Left's ideals, organizations and political approaches have been reshaped by a shifting political and social landscape. The inability to attract new voters, internal divisions, and the dominance of centrist politics and policies have left many questioning whether the Left can still offer a viable alternative to current systems of power. To do so, the Left must reinvent itself to revive Europe, possibly on new bases, and engage in dialogue with the rest of the world. With contributions from leading historians, political scientists, and thought leaders, this volume suggests new strategies for revitalization and renewal. Left invites readers to engage with the most pressing questions of our time: can the Left reclaim its influence? And what must it become to remain relevant in today's Europe?
