In its latest wave, globalization has broken down temporal and spatial boundaries, giving rise to new phenomena from communicational, economic, technological, cultural, social, and political perspectives that had not existed before. In this respect, globalization has created opportunities in some areas while posing threats in others; it has strengthened certain spheres while weakening others. This engendered three distinct responses to globalization. The first was support for globalization, expressed by most cultural universalists; the second was opposition to it, expressed by most cultural particularists; and the third was an attempt to seize its opportunities while countering its threats. Political Fiqh (jurisprudence) in Iran belongs to this third category and has sought to develop responses accordingly. The question, therefore, is what solutions Shiite political fiqh offers in addressing the challenges that globalization has posed to Iran’s national identity. The study employs descriptive, analytical, and historical research methods to address this question. Its objective is to identify these challenges and the corresponding solutions. The findings show that, in response to the challenges posed to the sources of national identity, Shiite political fiqh in Iran has derived solutions from principles such as nafy al-sabil (denial of domination), the expediency of the Islamic system, la zarar wa la dirar (no harm and no reciprocal harm), daf‘ al-afsad bi-l-fasid (averting the greater harm by accepting the lesser harm), al-amr bi-l-maʿrūf wa al-nahy ʿan al-munkar (enjoining good and forbidding evil), shura (consultation), difāʿ (defense), ʿadl (justice), and inṣāf (equity), iqāmat al-ḥudūd (the enforcement of divinely prescribed punishments), the principle of taslīṭ (control), and al-wafāʾ bi-l-ʿahd (the fulfillment of covenants).
