It then discusses how the scholarship on the IRI’s revolutionary outcome, regime consolidation, and state formation has disproportionately focused on coercion. The introduction explains the book’s main objective of pioneering and contributing to the academic literature on the mobilizational, developmental, and soft power dimensions of the IRI’s revolutionary outcome, regime consolidation, and state formation through the case of RJ. Methodologically, the introduction highlights the semi-structured interviews and archival documents on which the study is based. Thereafter, the introduction delves into the book’s organization and shares with the reader general findings from the project.
