The story is not the “death of religion,” as it may appear from social media snippets depicting once unheard of public concerts and women spurning the mandatory hijab, but a fundamental reordering of how Iranians relate to faith.
Recent surveys by the Netherlands-based Group for Analyzing and Measuring Attitudes in Iran (GAMAAN) found 68% oppose the continuation of the Islamic Republic. Support for its leader and revolutionary principles fell from 18% to 11% between 2022 and 2024.
A leaked culture ministry survey reported that 73% favor separating religion and state. A peer-reviewed article by Ali Sarihan of Maryland's St. Mary's College, published in the journal Religions puts support for a secular system at around 70%.
Yet other indicators show Iran is not secular in the familiar Western sense. The World Values Survey (WVS) still finds 96% identify as Muslim and only 1.3% as atheist.
Faith endures, it seems. It is political Islam that is losing ground.
Hidden secularism
Classic secularization theory imagined that modernization would push religion out of public life. Iran shows something more layered: personal belief can survive even as the political project built around it collapses.
Sociologist Asef Bayat has called this “post-Islamism”—a phase in which political Islam has exhausted its appeal, even as many Iranians retain some form of private faith.
Iran is not “non-religious,” Bayat argues. It is post-theocratic in its political aspirations.
Religious practice has thinned markedly.
Sarihan's study also suggests that the share of Iranians who “always or often” pray fell from 78% in 2015 to 55% in 2023—a steady decline shaped, and likely accelerated in recent years, by repression and economic crisis.
The WVS relies on face-to-face interviews, which in a country like Iran give respondents every incentive to conceal dissent or non-conformity.
Belief recast
Religious rituals remain part of everyday life.
The Shi'ite religious holy days of Muharram and Arbaeen still draw large crowds especially outside major cities, and shrines remain busy.
But for younger Iranians, who express the highest levels of political dissatisfaction, religion no longer aligns with state intrusion into private life.
The compulsory hijab, morality policing and the regulation of personal behavior have turned religion, for many, into a vehicle of control.
The widespread protests of 2022, known by their rallying cry of Woman, Life, Freedom, exposed this rupture. The slogans were never an assault on faith itself but on the state’s claim to define and enforce it.
On social media, hashtags rejecting the Islamic Republic sit comfortably alongside posts defending personal belief. The distinction between faith and religious governance has become unmistakable.
Coercion to choice
Iran’s path to secularization is unusual because it runs in two directions at once: from above and from below.
Heavy-handed enforcement—from hijab rules to cultural censorship—has alienated generations and inadvertently strengthened the case for separating religion and power.
GAMAAN’s highest recorded opposition to the theocratic system came at the height of the 2022 protests, when women’s bodily autonomy became the central battleground: four out of five respondents said they would vote “no” to an Islamic Republic in a hypothetical referendum.
Meanwhile, everyday acts of defiance are reshaping religious life from the ground up.
Women walk unveiled. Families who still value faith increasingly bypass official religious bodies. Younger Iranians look for ethics and spirituality beyond state-sanctioned channels.
God versus government
Two caricatures usually obscure the real picture. Iran is not a “godless society”: personal belief, ritual and religious meaning remain widespread. But nor is it the devout political community the state insists it governs.
The Islamic Republic’s project of political Islam has lost its authority, and most Iranians now prefer a secular political order.
The theocracy has produced one of the region’s strongest secularizing shifts—not through reform but through coercion. The more it has enforced religious rule, the more clearly Iranians have separated faith from the state.
Iran today stands between private, chosen belief and state-imposed religion.
The secularization of politics is now a structural threat to Islamic rule—one that often goes unnoticed amid a myriad of more immediate, louder crises.
