Democratization introduces the theoretical and practical dimensions of democratization. Focusing on the ‘global wave of democratization’ that has advanced since the early 1970s, this text examines the major perspectives, approaches, and insights that have informed research on democratization. The book is divided into four parts based on four aspects of democratization. Part One deals with theoretical and historical perspectives; Part Two focuses on causes and dimensions of democratization; Part Three looks at actors and institutions; and Part Four is concerned with regions of democratization such as Southern Europe, Latin America, the Middle East and North Africa, Sub-Saharan Africa, and East Asia. Topics include the distinction between democratic and undemocratic states, the role of democratization in foreign policy, and the contributions of social movements, protest, and transnational advocacy networks to democratic transition. Key themes covered in this thoroughly revised and updated second edition include: theories of democratization; critical prerequisites and driving social forces of the transition to democracy; pivotal actors and institutions involved in democratization; conditions for democratic survival and the analysis of failed democratization; demonstrations of how these factors have played a role in the different regions in which the global wave of democratization transplaced authoritarian and communist systems; and possible futures of democratization worldwide.
