At a time when debates over Islam, democracy, and political authority are intensifying across the globe, a new book from the London School of Economics and Political Science (LSE) turns the spotlight on an frequently enough-overlooked arena: Indonesia, home to the world’s largest Muslim population. “Mobilizing Mainstream Islam: The Politics of Orthodoxy in Indonesia in Comparative Perspective” examines how Islamic authority is constructed, contested, and mobilized in the world’s third-largest democracy-and what this reveals about the broader politics of religious orthodoxy today.
Launched at LSE, the book brings Indonesia into conversation with other Muslim-majority societies, challenging familiar narratives that frame Islamic politics primarily through the lens of the Middle East. Instead, it traces how “mainstream” Islamic organisations and scholars shape public life, influence state policy, and negotiate their role within a pluralistic political order. By unpacking the quiet, incremental work of defining and defending orthodoxy, the study sheds light on how religion can serve both as a stabilising force and a site of deep political struggle.
The book launch at LSE gathered scholars, students, and policymakers to discuss these questions and to explore why Indonesia’s experience matters for understanding the future of political Islam-and democratic governance-far beyond Southeast Asia.
Exploring the contested politics of Islamic orthodoxy in contemporary Indonesia
In post-authoritarian Indonesia, claims to speak for “mainstream Islam” have become a powerful political currency, drawing together state institutions, mass Islamic organizations and emerging moral entrepreneurs. Competing actors selectively invoke orthodoxy to police doctrinal boundaries, regulate public piety and shape legislation on issues ranging from blasphemy to gender and minority rights. This struggle unfolds not only in parliament or the courts, but across television studios, mosque pulpits and algorithm-driven social media feeds, where religious credentials and nationalist rhetoric are continually recalibrated. In this landscape, the label arus utama (mainstream) is less a neutral description than a strategic tool used to legitimize certain voices while marginalizing others branded as “liberal”, “radical” or “deviant”.
- State-ulama alliances that seek to stabilise religious authority while managing dissent
- Mass organizations competing to define acceptable belief, ritual and public conduct
- Digital preachers who repackage scripturalism for an online, youth-centric audience
- Counter-movements resisting top-down definitions of who counts as a “good Muslim” citizen
| Key Arena | Orthodoxy in Practice |
|---|---|
| Law & Policy | Blasphemy cases and local sharia-inspired bylaws |
| Education | Curriculum debates over pluralism vs. moral discipline |
| Media | Talk shows, dramas and sermons framing “moderate” Islam |
| Street Politics | Mass rallies claiming to defend religion and the nation |
Comparing Indonesian mainstream Islam with regional and global Muslim movements
While often portrayed as an outlier for its pluralist ethos and long-standing accommodation with democracy, Indonesia’s Islamic mainstream is deeply entangled with regional and global currents.Mass organisations such as NU and Muhammadiyah selectively absorb ideas from the Middle East, South Asia, and the West, yet filter them through Indonesia’s own history of anti-colonial struggle, state corporatism, and post-authoritarian reform. This has produced a distinctive configuration in which fiqh-based orthodoxy, Sufi-inflected piety, and modernist rationalism coexist uneasily but productively, allowing religious elites to position themselves as both guardians of national identity and actors in a wider umma. Simultaneously occurring, transnational Salafi and Islamist networks have pressured these mainstream bodies to clarify boundaries of orthodoxy, pushing them to rearticulate what counts as “moderate” or “authentic” Islam in the Indonesian polity.
These dynamics come into sharper focus when set against other Muslim-majority contexts, where state-ulama relations and the institutional architecture of Islam look markedly different:
- Middle East: Ministries of religious affairs frequently enough centralise authority, narrowing the space for civil-society based Islam that is so prominent in Indonesia.
- South Asia: Party-based Islam and sectarian competition create a more fragmented religious field than Indonesia’s broad-based mass organisations.
- Western Europe: Muslim councils and NGO networks must negotiate secular legal regimes, contrasting with Indonesia’s formal recognition of Islamic courts and law.
| Context | Key Islamic Actors | State-Religion Pattern |
|---|---|---|
| Indonesia | NU, Muhammadiyah | Negotiated pluralism |
| Egypt | Al-Azhar, official muftis | Centralised control |
| Pakistan | Parties, madrasa boards | Competitive Islamisation |
| France/UK | Muslim councils, NGOs | Minority governance |
Assessing the implications for democracy governance and civil society in Southeast Asia
Across Southeast Asia, efforts to mobilize mainstream Islamic authority are reshaping the balance between elected institutions, religious councils and civic actors. In Indonesia, the negotiation between state-backed orthodoxy and pluralist religious discourse offers a revealing lens on how democracies manage competing claims to moral legitimacy. Similar dynamics surface in Malaysia, Singapore and beyond, where governments selectively partner with Islamic organizations to project stability while also policing “deviant” or politically disruptive currents. This recalibration can bolster democratic resilience by marginalizing openly violent actors, yet it also risks hardening conservative social norms, narrowing acceptable dissent and sidelining minority voices within and beyond Muslim communities.Civil society groups, in response, are experimenting with new strategies of engagement, from legal advocacy and grassroots interfaith coalitions to digital campaigns that challenge official narratives of religious correctness.
These tensions are especially clear when comparing how different states institutionalize Islamic authority and regulate public debate. Where mainstream clerical bodies are embedded in bureaucratic structures, they can become quasi-state agencies, shaping law, media and education in ways that outlast electoral cycles. This raises pointed questions about who speaks for Islam, on what terms and with what democratic accountability.Key trends include:
- Formalization of religious councils as gatekeepers of public morality
- Strategic co-optation of moderate leaders to contain opposition
- Digital contestation over what counts as “authentic” Islamic politics
- Shrinking civic space for progressive and minority religious actors
| Country | State-Islam Relationship | Impact on Civil Society |
|---|---|---|
| Indonesia | Plural, competitive mainstream organizations | Opportunities for coalition-building but rising norm policing |
| Malaysia | Centralized Islamic bureaucracy | Strong state oversight, constrained rights advocacy |
| Singapore | Managed religious sphere via legal regulation | Stable environment, limited space for contentious politics |
Policy recommendations for scholars practitioners and policymakers engaging Muslim publics
Working with Muslim constituencies demands moving beyond assumptions that religious authority is either monolithic or easily co-opted. Scholars, practitioners and policymakers should invest in long-term relationships with diverse Islamic institutions, including women’s study circles, pesantren networks and urban youth communities, to understand how orthodoxy is negotiated on the ground. This means supporting locally-rooted research collaborations, funding autonomous survey work in multiple languages, and creating open-access platforms that return findings to the communities that generated the data. Crucially, engagement must be framed as a dialogue rather than an intervention: shared research agendas, co-authored outputs, and public forums where imams, activists and bureaucrats can contest findings in real time are more enduring than short-lived consultancy projects.
Policy innovation also requires recognizing that “mainstream” Islam is a field of competing projects, not a single stabilising force. Practitioners should map how state actors, religious councils and civil society groups each define acceptable belief and practice, and then design programmes that do not instrumentalise piety for security or electoral ends. Instead, support should flow to initiatives that defend pluralism, social justice and institutional integrity within Islamic frameworks.

In Summary
As debates over religious authority,civic identity and democratic resilience intensify across the globe,the questions raised by Mobilizing Mainstream Islam: The Politics of Orthodoxy in Indonesia in Comparative Perspective will only grow more urgent.By situating Indonesia’s Islamic institutions within a wider international landscape, the discussion at LSE underscored that “mainstream” Islam is neither static nor monolithic, but constantly negotiated between state actors, religious leaders and ordinary believers.
The book launch made clear that understanding how orthodoxy is defined, defended and deployed is crucial not only for scholars of Southeast Asia, but for anyone concerned with the relationship between religion and politics today. In mapping the shifting terrain of Islamic authority, this volume offers a lens on how democracies manage religious diversity-and how religious actors, in turn, shape democratic possibilities.
If Indonesia is frequently enough hailed as a test case for pluralist democracy in the Muslim world, then the contest over what counts as “mainstream” Islam is a test case within a test case. This new work, and the debate it has sparked at LSE, suggests that the future of that mainstream will be decided not in theory, but in the everyday struggles over institutions, narratives and power that define contemporary public life.
