In recent years, there has been a rise in social movements and organizations that challenge the very foundations of liberal democracy on a global scale. Discrepancies of interests, ideological or worldview contradictions, and identity differences are more likely now to transform into destructive conflicts, and violence is used as a legitimate method for attaining political and economic goals. Drawing on the knowledge accumulated in social and political psychology, this book scrutinizes these phenomena and provides an even deeper understanding of the nature of these conflicts. The book also addresses the imperfections of liberal institutions, which can exacerbate these divides, providing crucial context for understanding contemporary political tensions and their effects on the world's democracies.
