Dynamics of Democratization [PDF ebook] 
Elites, Civil Society and the Transition Process

The author assesses the main theories developed to account for and explain why and how authoritarian regimes give way to democratic ones. The book takes issue with the predominantly lite-centred focus of much of the literature, and illustrates how an understanding of democratization can be gained only if the role of civil society is taken into account.
