The collapse of the Ottoman Empire, a centuries-old imperial power that once stretched from the Balkans to the Arabian Peninsula, resulted from a confluence of economic decline, military defeats, and nationalistic uprisings. Among the internal dynamics that accelerated its dissolution, ideological resistance—often labeled conservatism—proved especially consequential. Ottoman conservatism was not a monolithic doctrine but a deeply ingrained attachment to Islamic law, the Sultan’s absolute authority, and the social hierarchies that defined the empire’s identity. This resistance to transformative change repeatedly impeded state-led modernization efforts, fragmented political authority, and ultimately fueled the secular nationalist reaction that gave birth to the Republic of Turkey.

The Roots of Ottoman Conservatism: Religion, Authority, and Identity

Ottoman conservatism drew its strength from a fusion of religious orthodoxy and political tradition. The Sultan was both temporal ruler and Caliph, the guardian of Islam’s holy places and the enforcer of sharia (Islamic law). The ulema—the learned class of religious scholars, judges, and jurists—commanded immense social prestige and played a central role in legitimizing state authority. Any reform that appeared to tamper with divinely ordained law or the Sultan’s absolute prerogative could be denounced as bid’a (reprehensible innovation).

This mindset was reinforced by the institutional weight of the Janissary infantry corps. Originally an elite slave-soldier force drawn from the devshirme system, the Janissaries by the 17th century had evolved into a hereditary caste with powerful economic interests and a deep-seated hostility toward military modernization. They controlled key guilds, engaged in commerce, and could depose sultans who threatened their privileges. Time and again, sultans who attempted to introduce European-style drilling, firearms, or administrative changes faced mutinies and depositions. The Janissaries’ attachment to their privileged status, cloaked in the rhetoric of defending the “old order,” epitomized the type of internal conservatism that would paralyze reform for generations. The Janissaries were only abolished in 1826 by Mahmud II in the bloody Auspicious Incident, a watershed moment that cleared the path for a new army but also deepened the rift between modernists and traditionalists.

The Tanzimat Reforms: A Clash Between Modernization and Tradition

By the early 19th century, territorial losses in Greece, Egypt, and the Balkans made the need for change undeniable. Mahmud II’s dramatic abolition of the Janissary corps cleared the path for a new army, but it also intensified the struggle between modernist bureaucrats and conservative elites. The empire’s answer came in the form of the Tanzimat reforms, a series of edicts issued between 1839 and 1876 that aimed to restructure administration, law, and education along European lines.

The Tanzimat proclaimed the equality of all subjects—Muslim and non-Muslim—before the law, a concept that directly challenged the traditional Islamic hierarchy in which dhimmis (protected non-Muslims) occupied a subordinate, albeit stable, position. The Gülhane Edict of 1839 and the Hatt-ı Hümayun of 1856 promised security of life, property, and honor for every Ottoman citizen. Yet these promises provoked fierce resistance from the ulema, provincial notables, and large segments of the Muslim population, who saw the granting of equal status to Christians and Jews as a violation of the sharia-based social contract. The reforms also undercut the traditionally privileged position of Muslims in the tax system and military service, breeding a deep sense of grievance.

Conservative opposition took both passive and violent forms. In Damascus in 1860, long-simmering resentment exploded into sectarian massacres of Christians, triggered by economic tensions and the perception that the Tanzimat had upset the sacred social order. Elsewhere, Muslim guildsmen and artisans protested the influx of European goods and the legal privileges afforded to foreign protégés under the capitulations. The Tanzimat reformers, often educated in the empire’s new secular schools and influenced by French legal codes, pushed ahead, but their efforts were persistently diluted. The Mecelle (the Ottoman civil code completed in 1876) tried to codify Hanafi jurisprudence in a modern format, yet it remained a compromise that kept sharia at the heart of personal status law while borrowing Western commercial principles. This half-measure satisfied neither committed secularists nor die-hard traditionalists. The fiscal strain of military reforms and the growing foreign debt further eroded the state’s capacity to enforce change.

The Hamidian Era: Autocracy and Islamic Conservatism

The short-lived First Constitutional Era (1876–1878) collapsed when Sultan Abdülhamid II used the catastrophic war with Russia as a pretext to suspend parliament and return to autocratic rule. His long reign (1876–1909) represented a distinct form of conservatism that married technological modernization with an intensified Islamic identity. Abdülhamid styled himself as the Caliph of all Muslims and sponsored pan-Islamist propaganda to rally support both inside the empire and among colonized Muslims in British India, Dutch Indonesia, and Russian Central Asia.

Under Abdülhamid II, the state expanded secular high schools, telegraph lines, and the Hejaz Railway—projects that imitated Western infrastructure while reinforcing the Sultan’s image as a pious modernizer. The railway, completed in 1908, facilitated the annual pilgrimage to Mecca and projected Ottoman influence in the Arabian provinces. At the same time, the regime tightened censorship, built a vast network of spies, and actively suppressed liberal, nationalist, and constitutionalist thought. Conservative religious elements enjoyed royal patronage, but they were also instrumentalized to delegitimize any opposition as un-Islamic. The ulema were co-opted through state salaries and control of the religious courts, making them dependent on the palace rather than independent voices. This strategy succeeded in delaying the empire’s collapse, but it deepened fault lines between the palace and the Western-educated officers and bureaucrats who would eventually form the Young Turk movement. The Hamidian approach also alienated non-Muslim communities, whose hopes for equality under the Tanzimat were dashed, and fueled ethnic nationalism among Arabs and Albanians who resented the Turkocentric caliphate.

The Young Turk Revolution and the Rise of Secular Nationalism

In 1908, the Committee of Union and Progress (CUP), a secret society of army officers, civil servants, and intellectuals, forced Abdülhamid to restore the 1876 constitution. The Young Turk revolution was initially greeted with widespread enthusiasm, but the restoration of parliament quickly exposed the chasm between the CUP’s secular, centralizing vision and the conservative sentiments of the Anatolian and Arab populace. The CUP’s ideology, heavily influenced by French positivism and German nationalism, viewed religion as an obstacle to progress and the empire’s salvation.

The most dramatic conservative counter-blow came in April 1909, in the form of the 31 March Incident. Soldiers of the Istanbul garrison, joined by religious students (softas) and members of the lower ulema, mutinied, demanding the restoration of sharia and the dissolution of the CUP. The mutineers chanted religious slogans and called for the caliph’s absolute authority. Although the uprising was crushed by the Action Army from Salonika, led by Mustafa Kemal among other officers, and Abdülhamid was deposed in favor of his brother Mehmed V, the event left an indelible mark on the CUP leadership. It reinforced their belief that religious conservatism was the chief obstacle to national survival and that Turkey’s future required a radical break with the Ottoman past. The CUP subsequently purged the army of conservative elements and tightened control over religious institutions. The 1909 uprising also accelerated the CUP’s shift toward authoritarian one-party rule, culminating in the 1913 coup that installed a triumvirate of Enver, Talat, and Cemal Pashas.

The Collapse: World War I and the End of the Empire

The Ottoman entry into World War I on the side of the Central Powers accelerated the empire’s disintegration. The CUP’s wartime policies, including the mass deportation and killing of Armenians, were driven by a nationalist-security ideology that had little room for the multi-confessional Ottoman identity once sustained by conservative religious frameworks. The Arab Revolt of 1916, backed by Britain, demonstrated that the Sultan-Caliph’s pan-Islamic appeal could not prevent the spread of ethnic nationalism. Sharif Hussein of Mecca, himself a Muslim leader, turned against the empire after the CUP’s secularizing policies alienated Arab elites. The use of Germany as a wartime ally also deepened the rift with Britain and France, leading to the loss of Arab provinces under the Sykes-Picot Agreement.

The Mudros Armistice of October 1918 and the subsequent Allied occupation of Istanbul, Anatolia, and the Arab provinces left the empire in shambles. The CUP leaders fled the country, and the Sultan’s government in Istanbul became a puppet of the Allies. It was at this moment that Mustafa Kemal (later Atatürk) and a group of nationalist officers launched the Turkish War of Independence from Ankara, explicitly rejecting both the Sultan’s government and the conservative-religious forces they held responsible for the empire’s ruin. The national movement gathered around the idea of a sovereign Turkish state, purged of the old imperial entanglements. In November 1922, the Grand National Assembly abolished the sultanate, separating the caliphate’s spiritual role from temporal power—a decisive step that moved the center of gravity from religion to the nation-state.

The Birth of the Turkish Republic: Atatürk’s Radical Secularism

Proclamation of the Republic on October 29, 1923, marked the formal end of the Ottoman order. Mustafa Kemal Atatürk and his associates believed that only a sweeping secularization program could inoculate the new state against the conservatism they identified with imperial decay. Within a few years, they launched an assault on the institutional pillars of religious authority, aiming to replace them with a modern, nationalist, and scientific worldview.

Abolition of the Sultanate and Caliphate

The caliphate, though stripped of political power after 1922, remained a potent symbol of unity for Muslims worldwide. In March 1924, the Assembly voted to abolish the caliphate entirely and exiled the last Ottoman caliph, Abdülmecid II, along with all members of the Ottoman dynasty. This act severed the centuries-old link between Islam and state legitimacy, drawing protests from conservative circles inside Turkey and across the Muslim world. The Indian Caliphate movement, which had supported Turkey during the war, was dealt a severe blow. The abolition was accompanied by the closure of the religious ministry and the transfer of its functions to a newly created Directorate of Religious Affairs, the Diyanet, which would control religious institutions under state supervision.

The state closed religious courts, abolished the office of Şeyhülislam (the chief religious authority), and adopted the Swiss Civil Code in 1926, which replaced sharia-based family law. Polygamy was outlawed, women gained legal rights in divorce and inheritance, and a secular marriage system was introduced. The 1924 Law on Unification of Education shut down the medreses (Islamic seminaries) and placed all schools under secular state control. Religious instruction was banned from primary and secondary schools for decades. In 1928, the Arabic script was replaced by a Latin-based alphabet, dramatically reducing the population’s direct access to classical religious texts and the Ottoman literary heritage. The wearing of the fez—seen as a symbol of Ottoman backwardness—was banned under the Hat Law of 1925, and dervish lodges (tekkes) and tombs (türbes) were closed. The adoption of the Western calendar and the Gregorian clock further signaled the break with the past.

Resistance and the Kurdish Sheikh Said Rebellion

These top-down reforms provoked a violent conservative backlash. In 1925, Sheikh Said, a Naqshbandi religious leader in the Kurdish southeast, raised a rebellion that combined Kurdish nationalist aims with a fierce defense of the caliphate and sharia. The uprising spread rapidly across the provinces of Diyarbakır, Elazığ, and Bitlis, drawing on the deep-rooted influence of Sufi orders and local tribal structures. The rebels captured several towns and declared the restoration of the caliphate. Ankara declared martial law and used the air force, freshly organized regular troops, and even Kurdish tribal levies loyal to the state to suppress the revolt. Sheikh Said was captured and executed, and the rebellion was crushed by mid-1925 after several months of heavy fighting. The event hardened Atatürk’s resolve to eliminate organized religious opposition. The Law on the Maintenance of Order granted the government extraordinary powers, and Independence Tribunals in the east purged perceived enemies of the regime, executing or imprisoning hundreds of religious leaders, tribal chieftains, and intellectuals. The rebellion also led to a campaign of forced Turkification and resettlement in the Kurdish provinces.

Conservatism’s Suppression and Its Subterranean Survival

The early Republic’s single-party rule under the Republican People’s Party enforced Kemalist secularism with remarkable thoroughness. Yet the outward silence of conservative religious sentiment masked a deep reservoir of popular piety. In the countryside, clandestine Quran courses continued in homes and mosques, and Sufi brotherhoods operated underground, often using commercial or cultural organizations as covers. The state’s aggressive secularism, especially the ban on religious education and the Arabic call to prayer, inadvertently created a victim narrative that later political movements would exploit. The iron-fisted control over religion also alienated many pious Turks who felt marginalized in the new republic.

When Turkey transitioned to multiparty politics in the late 1940s, the Democratic Party under Adnan Menderes successfully harnessed rural and religious conservative discontent. After its 1950 electoral victory, the government restored the Arabic call to prayer (banned under Atatürk), expanded Imam Hatip religious schools, and funded mosque construction. This pattern—state secularism periodically challenged by a conservative-populist resurgence—has defined much of modern Turkey’s political trajectory. The 1960 military coup, the rise of the Islamist National Salvation Party in the 1970s, and the AKP era post-2002 all reflect this ongoing tension. The Ottoman legacy of using Islam as a source of political legitimacy never fully disappeared; it reemerged in new forms that continue to shape the republic’s identity, from the official Diyanet’s growing budget to the political struggles over the headscarf and religious education.

Conclusion

The role of conservatism in the Ottoman collapse and the birth of modern Turkey was neither one-dimensional nor static. In the imperial context, conservative attachment to sharia and dynastic absolutism repeatedly stalled reforms that might have slowed the empire’s fragmentation. The Janissaries, the ulema, and the Hamidian counter-reformation each in their own way resisted the kind of radical change that might have saved the empire. After the empire’s dissolution, Mustafa Kemal’s radical secularism treated that same conservatism as the primary enemy of national survival and, in a deliberate act of state building, sought to erase it from public life. Yet the persistence of conservative religious identity, even under rigorous suppression, ensured that the ghost of the Ottoman order would remain a force in Turkish politics. The transition from multi-ethnic theocracy to secular nation-state was not a simple linear progress but a violent, contested, and incomplete rupture—one whose aftershocks still reverberate today in the debates over the role of religion in Turkish society and the meaning of the republic itself.
