The Institutionalization of Political Islam under the Leadership of Ayatollah Sayyid Ali Khamenei

This study investigates the structural, jurisprudential, and geopolitical evolution of Political Islam under the leadership of Ayatollah Sayyid Ali Khamenei (1989–2026). The central historical dilemma confronting twentieth-century Islamic movements has been the transition from charismatic, insurgent mobilization to durable, institutionalized governance without sacrificing ideological authenticity or capitulating to secular bureaucratic imperatives. While Western political science has frequently analyzed this transition through deterministic models—notably Olivier Roy’s thesis on the failure of Political Islam and Asef Bayat’s paradigm of post-Islamism—the trajectory of the Islamic Republic of Iran under Ayatollah Khamenei demonstrates a distinct and successful model of Islamic statecraft. Utilizing qualitative content analysis, conceptual history, and comparative institutional analysis, this article conceptualizes this transformation as Institutionalizing Guardianship. Under Khamenei’s guidance, Political Islam evolved from a revolutionary protest movement into a comprehensive, self-reproducing state system and civilizational project. This consolidation was achieved across four foundational dimensions: (1) the epistemological expansion of Shi‘i jurisprudence from individualistic casuistry into a macro-administrative jurisprudence of statecraft; (2) the translation of ideological goals into public policy via Article 110 of the Constitution and specialized supra-ministerial Supreme Councils; (3) the development of a resilient socio-institutional infrastructure integrating professionalized popular mobilization (the Basij), strategic industrial-security institutions (the IRGC), and socioeconomic foundations; and (4) the projection of a transnational, counter-hegemonic regional architecture known as the Axis of Resistance. The study demonstrates how this model systematically overcame external pressures, hybrid warfare, and economic sanctions, establishing an enduring framework for contemporary Islamic governance and civilizational progress.
