La République islamique d'Iran by Azadeh Kian-Thiébaut offers a comprehensive analysis of the political evolution and institutional structure of the Islamic Republic of Iran. The book traces the transformation from revolutionary theocracy under Ayatollah Khomeini to the consolidation of state authority in the post-revolutionary era. Drawing on historical context and political theory, Kian-Thiébaut examines key power dynamics, including the role of the Supreme Leader, the presidency, and the complex interplay between religious and secular institutions. With a focus on governance, legitimacy, and political reform, this work provides essential insights into contemporary Iranian politics and its implications for regional and global affairs.
