As attention of scholars shift from perils of presidentialism to perils of semipresidentialism in the recent decades, French style of cohabitation power sharing mode in the executive merits our endeavor to understand the micro-dynamics that is embedded in it. It includes how it emerged, how it was practiced and what consequences it produced. Such effort, if wisely applied, can probably be helpful in slowing down the rate of political system breakdown in many of the newly emerged democratic systems that emulate the French model. After an introduction to the blackbox of French cohabitation, the remainder of the dissertation is divided into eight chapters. Chapter 2 briefly reviews the existing literature on French cohabitation. Chapter 3 introduces the interpretive paradigm of qualitative research that is employed to analyze data and to facilitate theory building. In the 4th theoretical discussion chapter, three elements of practice theory approach ¡V temporality, duality of structure and unanticipated consequences are elaborated respectively. The three elements correspond to answer three research questions comprising how cohabitation emerged, how it was practiced and what kinds of consequences it produced. Chapter 5 to 8 display findings to the questions. They unravel for us other faces of French cohabitation which can be an active outcome of rationalization, a dynamic generator and a collective inevitable self-deception. Chapter 9 concludes by delineating theoretical and practical contribution of the dissertation.
