Iran at a Political Turning Point Popular Aspirations for Secular Governance in the Post Pahlavi and Islamic Republic Era

Iran, one of the world’s oldest civilizations, has oscillated between secular-nationalist prosperity and religiously dominated decline. This study traces Iran’s political history from antiquity to early 2026, focusing on the Pahlavi era (1925–1979) and the Islamic Republic (1979–present), and analyzes the roots of widespread public discontent in 2026 demanding secular governance. Using a mixed-methods approach, we integrate archival documents, socioeconomic indicators, human rights reports, and real-time data from the December 2025–January 2026 protests, including geolocated videos and thematic analysis of slogans. Results indicate severe economic collapse (rial depreciation > 50% in 2025), systemic human rights abuses, and nationwide protests across 60 + cities with strong pro-Pahlavi sentiment—the most significant since 1979. Findings suggest the Islamic Republic’s ideological rigidity has fostered isolation, repression, and stagnation, whereas secular-nationalist frameworks historically promoted prosperity and global engagement. The 2025–2026 uprising represents a critical threshold, reflecting popular desire for a secular renaissance beyond theocratic rule.
