Shiite Political Islam and the Future of the Iranian Revolution

It is impossible to consider the future of political Islam in the Middle East without examining the Shiite experience, particularly the 1979 Iranian Revolution. The revolution did more than transform Iran’s political system. It marked a historic turning point in the place of Shiites within the Muslim world. It also gave rise to a political and intellectual project that extended beyond Iran’s borders, reshaping the balance of power and changing how Islamic history itself is understood.

The Rise of the Shiites and the Reinterpretation of History

For centuries, much of the Muslim world lived under the authority of states and political and cultural institutions dominated by Sunnis. As this dominance became more firmly entrenched, the Sunni interpretation of Islamic history became the most widespread and the most prominent in the public sphere.

Shiite thought had a rich religious, legal, and philosophical heritage, along with a distinct interpretation of many events in Islamic history. Yet this interpretation remained largely confined to Shiite circles.

The Iranian Revolution changed that.

With the establishment of a powerful Shiite Islamic state, followed by the growing political prominence of Shiites in several countries across the region, their long-marginalized interpretation of history moved to the center of debate in the Muslim world.

When a community that has long been marginalized asserts itself politically, its interpretation of history also gains visibility and influence.

Questions that many had considered settled for centuries consequently resurfaced: What happened after the Prophet’s death? How was power transferred? Who was entitled to succeed him? How should the conflict between Ali and Muawiya, the First Fitna, and Karbala be understood? Was the caliphate an immutable religious institution or a political arrangement that emerged from particular historical circumstances?

These questions were nothing new to the Shiite tradition. What changed was that the political rise of the Shiites gave them the means to bring these issues forcefully into public debate across the Muslim world. It also compelled Sunni thinkers to revisit many of them, either to defend the traditional Sunni interpretation or to reconsider it.

Perhaps one of the most significant intellectual consequences of the rise of Shiite political Islam lies here: it has done more than offer an alternative reading of history; it has helped challenge the very idea that Islamic history can be understood through a single, definitive interpretation.

Where Does the Sacred End and History Begin?

This line of thought raises a question that goes far beyond the Sunni-Shiite divide: what, in the Islamic experience, truly belongs to the realm of the sacred, and what is historical but has come to be regarded as sacred?

For believers, the Quran is sacred, and the Prophet holds a sacred place in the Muslim consciousness. But does that mean that everything that happened after the Prophet’s death should also be considered sacred?

Are the political decisions made by the Prophet’s companions sacred? Is the caliphate a religious model to be followed? Are the Umayyad, Abbasid, and Ottoman states sacred Islamic models, or human political experiments that emerged in particular historical contexts, evolved over time, and sometimes came into conflict with one another?

The question can even be extended to the Prophet’s own political experience: was the state he established in Medina an immutable part of the religious message, or was it a response to the realities of seventh-century society?

These questions inevitably call for a distinction between religion and the history of Muslim societies, between the text and its interpretation, and between the sacred and the human effort to interpret it.

For believers, the Quran is sacred, but its interpretation is a human endeavor. Fiqh (Islamic jurisprudence) is a vast Islamic intellectual heritage, but it is the product of human efforts to understand religious texts and engage with the realities of their respective societies.

It is therefore legitimate to revisit many of the political, social, and legal concepts that have taken shape over the course of history, so that Islam can evolve alongside humanity and society, rather than seeking to bring contemporary societies back to the conditions of a world more than a thousand years ago.

Perhaps this is one of the most significant intellectual openings made possible by the rise of Shiite thought, even if it has not always pursued this line of inquiry to all its logical conclusions.

The Iranian Revolution: Breaking Out of the Margins

The Iranian Revolution did more than reshape perceptions of history. It also changed how Shiites viewed themselves and their ability to shape the course of events.

It demonstrated that a Shiite Islamist movement could overthrow a powerful regime, build a modern state, and sustain it through war, sanctions, and international isolation.

Iran also developed significant scientific, industrial, technological, and military capabilities. Shiite political thought thus evolved from a tradition shaped by a community long excluded from power into a political current confident in its ability to build a state, project power, and influence the future of the region.

That confidence extended beyond Iran’s borders. In Lebanon, Iraq, Yemen, and elsewhere, Shiites became an influential political, military, and social force in the regional balance of power.

But therein lies the paradox.

The very success that gave Shiite political Islam its historical significance brought it face to face with its greatest challenge: moving from revolution to the state.

From Revolutionary Legitimacy to State Legitimacy

Leading a successful revolution is one thing; governing a society is another.

A revolution can draw on ideology, mass mobilization, sacrifice, and the struggle against enemies. A state, by contrast, must deliver a viable economy, freedom, justice, opportunities, security, and a good quality of life for its citizens.

Nearly half a century after the Iranian Revolution, the question is no longer whether Shiite political Islam can come to power. It has already done so and established a powerful state.

The question now is whether it can transform itself once in power.

Iranian society today is no longer the society it was in 1979. The role of women, attitudes toward individual freedoms, and relations between citizens and the state have all changed. The digital revolution, social media, and, more recently, artificial intelligence have also made it harder for the state to control the flow of information and dictate how people live.

The doctrine of Vilayat al-Faqih now faces the same question that Shiite thought raised about the caliphate: where does political power derive its legitimacy?

Vilayat al-Faqih offered an answer to the question of who should exercise power in the absence of the Imam. But it also raised new questions: What are the limits of the authority of the jurist-theologian when it comes into conflict with the will of the people? What happens when religious authority clashes with popular will? Can a political doctrine that emerged in the twentieth century be regarded as the definitive form of Islamic government?

The paradox runs deep. The very tradition of thought that helped reopen the debate over Islamic history and challenge the legitimacy of the regimes that emerged from it must now subject its own political experience to the same critical scrutiny.

From a Project of Liberation to a Struggle for Influence

The Shiite project has also faced another challenge beyond Iran’s borders.

Initially presented as a revolution of the oppressed against hegemony, the Iranian Revolution gradually came to be seen by Iran’s adversaries and segments of Arab society as an attempt to expand its regional influence.

The expansion of Iranian power and the growing influence of armed movements linked to Tehran have reignited the Sunni-Shiite divide, giving it a political and geopolitical dimension that extends beyond religious differences.

This contradiction is particularly evident among movements that derive their legitimacy from resistance.

Resistance can confer broad legitimacy on a movement confronting occupation or aggression. The picture becomes more complicated, however, when that movement becomes a permanent fixture of the political system.

Who decides on war and peace? How can state sovereignty be reconciled with the presence of an armed organization pursuing its own military strategy? How can a movement move from the legitimacy it derives from resistance to the legitimacy that comes with exercising power through state institutions?

Hezbollah in Lebanon, along with certain armed Shiite groups in Iraq and elsewhere, thus finds itself at the center of a broader crisis.

Shiite political Islam has demonstrated its ability to build up a position of power. The question now is whether it can translate that power into a stable state and a prosperous society.

Iran and the Future of the Shiite Political Project

The future of the Islamic Republic itself is the biggest question facing Shiite political Islam.

Sunni and Shiite political Islam differ in one fundamental respect. Sunni political Islam is spread across a range of states, movements, and schools of thought. It has no single political hub whose downfall would necessarily bring the entire project to an end.

Shiite political Islam, as it took shape after 1979, is built around one clearly defined center: Iran.

Tehran has done more than provide an ideological framework for Shiite political Islam. It has shown that the project can be embodied in a state and given allied movements the political, strategic, and material backing they need to expand their influence.

Any sweeping change to Iran’s political system would therefore reverberate far beyond its borders.

What if Vilayat al-Faqih were challenged or redefined? What if Iran gradually moved toward a more secular, pluralistic state while continuing to see Islam as a core part of its identity? Or what if the country continued to advance scientifically and economically as the religious establishment’s grip on the state loosened?

These scenarios raise a particularly difficult question for Shiite political Islam:

If Iran could remain powerful and continue to develop without the political model born of the 1979 Revolution, what would justify that model’s continued legitimacy?

The implications would extend directly to Iran’s allies across the region. If Tehran itself were to reconsider the principle of Vilayat al-Faqih, movements beyond its borders that subscribe to the doctrine would find it harder to defend it as a lasting political model. And if Iran began putting domestic development and normalized relations with other countries ahead of its regional ambitions, movements whose standing rests on Tehran’s drive for regional influence would have to rethink their position.

Shiism Will Survive. But What Will Become of Shiite Political Islam?

It is important to distinguish between Shiism and Shiite political Islam.

Shiism emerged more than a thousand years before the Islamic Republic. It rests on a rich religious, legal, and philosophical tradition, as well as social and religious institutions that are independent of the Iranian state. A change of regime in Iran would not, therefore, spell the end of Shiism.

It is the political project that took shape after 1979 that could face an existential crisis. Shiite political Islam brought religion, the state, Vilayat al-Faqih, and the pursuit of regional power together within a single political model.

Its future is therefore closely tied to that of the Islamic Republic.

If the regime manages to reform itself and rethink its relationship with the state, society, individual freedoms, women’s rights, human rights, democracy, and pluralism, Shiite political Islam could develop a new model and find a way to endure.

But if the regime fails to adapt and Iran undergoes a radical transformation, the consequences could reach far beyond a change of government. An entire chapter in the history of Shiite political Islam, which began with the 1979 Revolution, could come to an end.

The Struggle for the Future

Ultimately, the greatest challenge facing Shiite political Islam is neither Sunni, American, nor Israeli. It is history itself.

The Iranian Revolution enabled Shiites to break out of political marginalization, give fresh impetus to their own reading of Islamic history, reopen debates over the caliphate, the imamate, legitimacy, and power, and prove that Shiite political Islam could build a state and establish itself as a regional power.

But yesterday’s achievements do not guarantee tomorrow’s survival.

In the twenty-first century, no political project can rely solely on the legitimacy of events that took place fourteen centuries ago. Nor can the Islamic Republic indefinitely draw legitimacy from a revolution that took place in 1979.

The question is no longer whether Shiite political Islam can come to power.

It is whether it can question its own foundations once it is in power.

Can it distinguish the sacred from the historical? Can it reassess the principle of Vilayat al-Faqih, just as it has reassessed the caliphate? Can it move from revolutionary legitimacy to legitimacy earned through results, from legitimacy rooted in doctrine to legitimacy grounded in the will of citizens, and from protecting the regime to protecting people?

If it can, its next contribution to Islamic thought could prove even more significant than its rise to power.

But if it shuts down criticism after using it to reinterpret history, the resulting crisis will not be confined to Iran. It could engulf the entire Shiite political project that has grown around the Islamic Republic.

Here lies the great paradox:

The Iranian Revolution brought Shiite political Islam in from the periphery of history. Today, its future may depend on whether it can free itself from the grip of the very revolution that made its rise possible.

It succeeded in reopening the debate over the past.

Its real test now is whether it can help shape the future.

If Iran Changes, What Will Become of the Project?

A change of course in Iran would not necessarily spell the immediate end of Shiite political Islam. It could instead usher in a period of realignment, potentially more far-reaching than the transformation set in motion by the Iranian Revolution itself.

Since 1979, Iran has established itself as the political and strategic hub of the Shiite project in the region. Over time, numerous Shiite forces have aligned themselves with Tehran to varying degrees, while Iranian influence has become a major factor in the balance of power in Lebanon, Iraq, Yemen, and beyond.

But what if that hub itself were to change?

If Iran moved toward a political system built on civil institutions, if the principle of Vilayat al-Faqih lost some of its weight, or if the line between religious authority and the running of the state became more clearly drawn, Shiite movements aligned with the Iranian model would face a crisis of identity and legitimacy, not merely the loss of a political ally.

Three paths could then lie ahead for these movements.

The first would be to cling to the old model, even as it began to lose ground in Iran itself. That would be a difficult position to defend: how could these movements promote abroad a model that its own birthplace was beginning to abandon?

The second would be to reinvent themselves as national political forces, rooted more firmly in their own countries than in a wider regional project. Hezbollah, for instance, would have to redefine its identity and role primarily within the framework of the Lebanese state. In Iraq, Shiite forces would likewise need to draw more of their legitimacy from Iraqi society and state institutions, rather than from their place within a regional axis.

The third possibility, and the most significant in intellectual terms, would be the emergence of a new form of Shiite political Islam, no longer centered on Iran or bound by the principle of Vilayat al-Faqih.

Such a shift could bring the diversity that already exists within the Shiite tradition to the fore and open the door to a different understanding of the relationship between religious authority and the state. It could also make room for a model that reconciles religious identity with a civil state, democracy, human rights, and pluralism.

Shiite political Islam, long centered on Iran, could then branch out into distinct national political currents.

That would be a major turning point.

Rather than a single center with allied forces orbiting around it, different forms of Shiite political expression could emerge in Lebanon, Iraq, the Gulf states, and Iran itself, each shaped by its own society, political system, and national interests.

The paradox runs deeper still. In the short term, a change in Iran could weaken Shiite political Islam. Over time, however, it could also free Shiite political thought from its dependence on a single regime.

The question, then, is not simply whether Shiite political Islam would survive a change in Iran, but what form it would take.

The model that emerged in 1979, built around the Iranian Revolution, Vilayat al-Faqih, and a regional axis, could disappear without ending Shiite political participation.

The Middle East would then enter a new phase in its history: a shift from a Shiite political project driven by a state to Shiite communities shaping their own national political projects.

Perhaps this is the most significant transformation of all: Shiites could move away from a project aimed at reshaping the region and focus instead on building the states in which they live. Citizenship, rather than sectarian affiliation or alignment with a regional axis, would become the main source of political legitimacy.
