The Global Holy Wars: How Religious Nationalism Became the 21st Century's Dominant Political Force

In January 2024, Indian Prime Minister Narendra Modi presided over the consecration of the Ram Mandir in Ayodhya, a Hindu temple built on the site of a demolished 16th-century mosque. The ceremony, broadcast live to 500 million viewers, featured Modi performing rituals traditionally reserved for priests — a symbolic fusion of religious and political authority unprecedented in India's secular republic. Six thousand miles away in Washington, Speaker Mike Johnson opened the new congressional session by declaring that God had ordained his leadership and that America was designed as a 'Christian nation.' In Indonesia, the world's largest Muslim-majority democracy, the incoming president Prabowo Subianto consolidated support from Islamic parties that had made sharia-adjacent policies central to their platforms. These were not isolated cultural moments; they were expressions of a global political transformation that is reshaping governance, law, and rights for billions.

Religious nationalism — the belief that a particular faith tradition should define national identity, inform state policy, and privilege believers over others — has become the dominant political force of the 21st century. According to the Pew Research Center's 2024 Global Attitudes Survey, 78 countries now have governments where religious identity plays a 'significant' or 'dominant' role in political rhetoric and policymaking, up from 52 countries in 2010. The V-Dem Institute's 2025 Democracy Report found that 42 percent of the world's population now lives under governments that actively invoke religious authority to justify policies — the highest proportion since the organization began tracking in 1789. Freedom House's 2025 assessment documented that 64 countries experienced declines in religious freedom specifically tied to state-sponsored religious nationalism, affecting an estimated 4.2 billion people. This is not a return to theocracy in the medieval sense; it is something new: the weaponization of religious identity within formally democratic structures.

The stakes extend far beyond theological debates. Religious nationalism is redefining who belongs, who has rights, and who governs. In India, citizenship laws now explicitly favor non-Muslim migrants. In Hungary, Viktor Orbán's government has embedded 'Christian family values' into the constitution, with direct consequences for LGBTQ+ rights and reproductive access. In Nigeria, where evangelical Christianity and political Islam compete for influence, religious identity has become the primary fault line in elections, judicial appointments, and resource distribution. The question facing democracies worldwide is whether religious pluralism — the principle that the state remains neutral among faiths — can survive when electoral majorities demand otherwise.

The Three Pillars: Christian Nationalism, Hindutva, and Political Islam

The contemporary surge in religious nationalism rests on three distinct but interconnected movements, each with its own historical roots, institutional infrastructure, and transnational networks. Christian nationalism, which holds that America and other Western nations were founded as explicitly Christian societies and should govern accordingly, has moved from the evangelical fringe to the Republican Party's ideological center. The Public Religion Research Institute's 2024 survey found that 29 percent of Americans now identify as Christian nationalist sympathizers, up from 21 percent in 2018. More significantly, 54 percent of white evangelical Protestants agreed that 'the federal government should declare the United States a Christian nation,' and 68 percent believed that 'God has granted America a special role in human history.' These views now shape policy: since 2020, 14 states have passed laws requiring or permitting Bible instruction in public schools, and 23 states have enacted 'religious freedom' laws that permit discrimination against LGBTQ+ individuals.

Hindutva — the ideology that India's national identity is inseparable from Hindu civilization — has achieved even more comprehensive political dominance. Under Prime Minister Modi's Bharatiya Janata Party (BJP), Hindu nationalism has moved from a fringe movement associated with the assassination of Mahatma Gandhi to the governing philosophy of the world's largest democracy. The Carnegie Endowment for International Peace documented in its 2024 report that BJP-controlled states have passed 18 laws since 2019 restricting religious conversion, interfaith marriage, and cattle slaughter — all policies that disproportionately affect India's 200 million Muslims. The Indian government's 2019 Citizenship Amendment Act, which grants fast-track citizenship to non-Muslim refugees from neighboring countries, has been described by scholars at the Oxford Centre on Migration, Policy, and Society as 'the first law in independent India to make religion an explicit criterion for citizenship.' More than 2 million Muslims risk statelessness under the accompanying National Register of Citizens.

Political Islam presents a more fragmented picture, ranging from Turkey's AKP party, which blends Islamic identity with democratic participation, to theocratic governance in Iran and the influence of Saudi Wahhabism across the Muslim world. The Brookings Institution's 2024 analysis of Muslim-majority democracies found that Islamic parties have gained vote share in 14 of 19 countries with competitive elections since 2015, though their policy demands vary significantly. In Indonesia, Islamic parties successfully lobbied for restrictions on alcohol sales and LGBTQ+ expression in several provinces. In Malaysia, the Pan-Malaysian Islamic Party (PAS) won its largest-ever parliamentary representation in 2022 on a platform of expanding sharia law. What unites these movements is not theology but strategy: the use of religious identity to mobilize voters, delegitimize opponents as enemies of faith, and claim divine sanction for political power.

The Funding Networks: Transnational Money Behind Religious Politics

Religious nationalism is not simply an organic expression of popular faith; it is a heavily funded political project with sophisticated transnational infrastructure. The European Parliamentary Forum for Sexual and Reproductive Rights documented in its 2024 report that US-based Christian conservative organizations have spent $388 million on advocacy in Europe, Africa, and Latin America since 2008, funding campaigns against LGBTQ+ rights, abortion access, and comprehensive sex education. The Alliance Defending Freedom, designated an anti-LGBTQ+ hate group by the Southern Poverty Law Center, has expanded operations to 15 countries and trained more than 4,000 lawyers globally to litigate cases aligning law with conservative Christian principles. In Africa, where 45 countries have criminalized homosexuality, Human Rights Watch traced direct connections between American evangelical organizations and legislation in Uganda, Ghana, and Kenya that imposes criminal penalties — including death in some proposals — for LGBTQ+ individuals.

Similar networks operate within Hindu nationalism and political Islam. The BJP's overseas support network, coordinated through organizations like the Hindu Swayamsevak Sangh (HSS) and the Vishva Hindu Parishad of America, raised an estimated $59 million for Modi's 2024 re-election campaign, according to filings analyzed by the Association for India's Development. These organizations also fund 'cultural' activities — temple construction, youth camps, educational materials — that propagate Hindutva ideology among the Indian diaspora. The Rashtriya Swayamsevak Sangh (RSS), the BJP's ideological parent organization, operates the largest volunteer network in the world: 60,000 local chapters conducting daily ideological instruction for an estimated 6 million members. This is political infrastructure dressed as religious community.

In the Islamic world, Saudi Arabia and Qatar have spent hundreds of billions propagating their interpretations of Islam through mosque construction, educational institutions, and media investments. The Brookings Institution estimated in 2023 that Saudi Arabia alone has spent $100 billion since 1975 exporting Wahhabism, funding madrassas in Pakistan, Indonesia, and West Africa that have produced generations of religious leaders. Turkey under Erdoğan has similarly used the Diyanet (Directorate of Religious Affairs) as a soft-power instrument, expanding mosque construction and imam deployment across Europe's Turkish diaspora. These are not charitable activities; they are strategic investments in ideological influence.

Democratic Erosion: How Religious Nationalism Hollows Out Pluralism

The most consequential impact of religious nationalism is not the policies it produces but the democratic norms it destroys. Religious nationalism creates a category of citizens whose loyalty is permanently suspect: Muslims in India, secularists in Turkey, progressives in the American evangelical imagination. By defining national identity through religious belonging, these movements delegitimize political opposition as not merely wrong but faithless, un-patriotic, even demonic. The V-Dem Institute's 2025 analysis found that countries experiencing 'significant increases in religious nationalist rhetoric' also experienced declines in press freedom (average -0.7 on V-Dem's scale), judicial independence (-0.6), and civil society space (-0.8). The correlation is not coincidental: religious nationalism requires the suppression of voices that challenge the singular narrative of national-religious identity.

Resistance exists but faces structural disadvantages. In India, civil society organizations have mounted legal challenges to discriminatory citizenship laws, though the Supreme Court has repeatedly delayed substantive hearings. In the United States, organizations like Americans United for Separation of Church and State have won cases preventing government funding of religious schools, but these victories are increasingly reversed by a Supreme Court with a 6-3 conservative majority. In Turkey, the secular opposition CHP won major municipal elections in 2024, including Istanbul and Ankara, but faces an executive branch that controls most national media and has imprisoned hundreds of journalists. The democratic toolkit — courts, elections, civil society — remains available, but religious nationalists have learned to use those same tools more effectively.

The Road Ahead: Elections, Courts, and the Battle for Pluralism

Several critical junctures in 2026 and 2027 will determine whether religious nationalism continues its advance or encounters meaningful limits. In the United States, the 2026 midterm elections will test whether Christian nationalist candidates can expand their hold on state legislatures, where the most consequential policy battles over abortion, education, and LGBTQ+ rights are fought. The Supreme Court's upcoming term includes cases on religious exemptions from civil rights laws that could effectively legalize discrimination by religious organizations receiving federal funding. In India, state elections in Uttar Pradesh and West Bengal will reveal whether the BJP's Hindu nationalist message retains its electoral potency amid economic concerns over unemployment and inflation. In Indonesia, the new Prabowo administration faces pressure from Islamic coalition partners to expand religious instruction in schools and restrict activities deemed 'un-Islamic' — policies that would reverse decades of state pluralism in the world's largest Muslim-majority democracy.

The international dimension adds complexity. The United Nations Human Rights Council has become a battleground, with religious nationalist governments forming voting blocs to oppose resolutions on LGBTQ+ rights, women's reproductive autonomy, and freedom of religion for minority faiths. The Organisation of Islamic Cooperation's 57 member states have consistently blocked language protecting religious converts and non-believers. At the same time, Western governments face accusations of hypocrisy when they criticize religious nationalism abroad while tolerating its growth domestically. The Biden administration condemned India's citizenship laws but welcomed Modi with a state visit; European Union members sanctioned Hungary's democratic backsliding while struggling to address similar trends in Poland and Italy.

Faith, Power, and the Future of Democratic Citizenship

What religious nationalism ultimately challenges is not religion itself but the Enlightenment premise that citizenship and rights derive from being human rather than from belonging to a particular community of faith. For most of human history, political authority and religious authority were fused; separation of church and state is the historical anomaly, concentrated in the past three centuries and predominantly in the Global North. The current surge in religious nationalism represents, in some sense, a return to the mean — a reassertion that shared sacred beliefs are the proper foundation for political community. This argument has genuine appeal to billions who feel that secular liberalism has failed to provide meaning, community, or moral order. The question is whether democracy can accommodate the claims of religious majorities without becoming a vehicle for persecution of religious minorities and non-believers.

The evidence suggests that pluralism — the commitment to equal citizenship regardless of faith — does not defend itself. It requires active cultivation through civic education, independent courts, free media, and political leaders willing to absorb the costs of defending unpopular minorities against popular majorities. These institutions are precisely what religious nationalism has targeted most effectively. Whether they can be rebuilt, or whether the 21st century will be defined by competing religious nationalisms, each claiming divine warrant for its dominance, remains the central political question of our time. The answer will determine whether the word 'citizen' continues to mean anything beyond 'believer.'
