Democracy in the twenty-first century faces a number of major challenges, populism, neoliberalism and globalisation being three of the most prominent. This book examines such challenges by investigating how the conditions of democratic statehood have been altered at several key historical intervals since 1945. It demonstrates that the formal mechanisms of democratic statehood, such as elections, have always been complemented by civic, cultural, educational, socio-economic and constitutional institutions that mediate between citizens and state authority. Rearticulating critical theory with a contemporary focus, the book shows why a sociological approach is urgently needed to address conceptual deficits and explain how the formal mechanisms of democratic statehood need to be complemented and updated in new ways today.
