This book analyses political leadership, addressing key questions central to the ongoing debate on the transformation of contemporary democracies. What exactly is political leadership? How does the relationship between leadership and power shape democratic transformations? What role do individuals play in broader historical processes? How does the personalisation of politics manifest, and how does it differ between leader democracy and populism? Is there still room for charismatic leadership in modern democracies and societies? These are some of the critical questions explored in this volume. The book traces the sociological relationship between leadership and power from foundational theories in the social sciences, through the personalisation of politics, to the rise of leader democracy and populist leadership. This book will be of interest to scholars, students, and practitioners in the fields of political sociology, political science, and leadership studies, as well as anyone engaged in understanding the evolving dynamics of leadership in contemporary democracies.
