People power explores the history of the theory and practice of popular power. Western thinking about politics has two fundamental features: 1) popular power in practice is problematic and 2) nothing confers political legitimacy except popular sovereignty. This book explains how we got to our current default position, in which rule of, for and by the people is simultaneously a practical problem and a received truth of politics. The book asks readers to think about how appreciating that history shapes the way we think about the people's power in the present. Drawn from the disciplines of history and political theory, the contributors to this volume engage in a mutually informing conversation about popular power. They conclude that the problems that first gave rise to popular sovereignty remain simultaneously compelling, unresolved and worthy of further attention.
