Azadeh Kian‑Thiébaut examines the evolution of the Islamic Republic of Iran from the early dominance of the Supreme Leader—often referred to as the *Guide*—to a modern state increasingly guided by pragmatic considerations of power and survival. Drawing on political analysis, historical context, and contemporary events, the book traces how ideological rhetoric has been tempered by the necessities of governance, economic pressures, and international relations. Kian‑Thiébaut highlights the tension between revolutionary ideals and the realities of statecraft, showing how the regime balances religious legitimacy with the demands of a complex, modern society. The work offers a concise yet insightful overview of Iran’s political trajectory, making it valuable for readers interested in Middle Eastern politics, state formation, and the interplay between ideology and practical governance.
