Mustafa Kemal Atatürk

Overview

Mustafa Kemal Atatürk was an Ottoman military commander who led the Turkish nationalist movement and became the founder and first president of the Republic of Turkey. He organized resistance in 1919 as foreign armies occupied Ottoman lands after the First World War. His movement rejected the Treaty of Sèvres, won a series of military victories, abolished the Ottoman Sultanate in 1922, and secured a new peace settlement at Lausanne in 1923. The republic established that year replaced the empire with a sovereign national state.

Atatürk’s presidency changed Turkey’s political and religious institutions. He abolished the Ottoman Caliphate in 1924, curtailed religious institutions’ public authority, and pursued secular government and a pro-Western national orientation. His reforms also imposed restrictions on religious expression, including a prohibition on Hebrew instruction in schools that harmed Turkish Jews. The effects of his rule therefore include both the creation of a durable secular republic and the costs that state-directed reform imposed on minority communities and religious practice.

Atatürk remains a defining figure in Turkish public life. The Republican People’s Party, or CHP, which he founded, continues to uphold secularism and nationalism among its founding values. His settlement of religion’s place in government remains a point of conflict under President Recep Tayyip Erdoğan. Erdoğan’s 2020 conversion of Hagia Sophia into a mosque reversed Atatürk’s decision to make it a museum and became a prominent symbol of the different political courses associated with the two leaders.

Early life

Atatürk was born Mustafa Kemal in 1881 in Salonika, then part of the Ottoman Empire. He was educated in Ottoman public schools and military institutions, which shaped his outlook before the Turkish Republic existed. His career grew from an empire already engaged in westernizing reform. During the eighteenth and nineteenth centuries, Ottoman rulers had pursued changes in education and government in response to military and political pressure from Europe. Atatürk’s later program extended and redirected that history; modernization did not begin with the republic.

Military education gave Mustafa Kemal a route into public service and command. He trained within the institutions of the state whose collapse he would later confront. His experience connected military organization, political leadership, and the question of how a state could preserve its independence. By the end of the Ottoman period he was a highly decorated commander, with a reputation established before he led the nationalist movement. That background helped him organize forces able to challenge both the postwar settlement and the authority of the Ottoman government that accepted it.

The empire’s defeat in the First World War transformed the setting in which Mustafa Kemal acted. The Ottoman government faced occupation of its lands and a proposed peace that sharply limited its future authority. The crisis placed competing ideas of legitimacy before the public: continued rule by the Sultanate and acceptance of an externally imposed settlement, or a nationalist government claiming to speak for Turkey. Mustafa Kemal became the principal leader of the second course.

Career

In 1919, Mustafa Kemal organized resistance to Allied forces and took the lead in the Turkish National Movement. The movement arose after foreign armies entered Ottoman lands. It presented itself as the exclusive Turkish political force and refused to recognize the legitimacy of the Treaty of Sèvres. After the treaty was signed, Mustafa Kemal demanded complete independence. His position made sovereignty, rather than revision of a few treaty provisions, the central objective of the nationalist struggle.

The Treaty of Sèvres became the clearest expression of the settlement the nationalists opposed. The Ottoman government signed it while exercising limited authority, and foreign occupation had already altered conditions on the ground. Mustafa Kemal’s movement rejected both the treaty and the assumption that the Sultan’s government could settle Turkey’s future without the nationalist forces. Victories against foreign armies allowed the Turkish National Government to overturn Sèvres in practice before a replacement treaty was signed. Military success gave its demand for independence diplomatic force.

Turkish nationalists led by Atatürk abolished the Ottoman Sultanate in 1922, bringing the empire’s ruling institution to an end. The abolition separated the emerging national government from the imperial dynasty and removed a competing source of political authority. The Ottoman Caliphate, a religious institution associated with the Sultanate, remained briefly after the Sultanate’s abolition. Its survival did not restore the old imperial order. Atatürk’s government ended the Caliphate in 1924 as part of its wider secular transformation.

The Treaty of Lausanne, signed on July 24, 1923, replaced Sèvres and secured the international position of the new Turkish state. Atatürk’s government achieved recognition of Turkey’s complete sovereignty in Anatolia, southeastern Thrace, and some islands in its territorial waters. Lausanne defined borders that have continued to shape the republic. It also protected minority social institutions, funds, and schools. The settlement marked the diplomatic outcome of the Turkish War of Independence and the defeat of the earlier plan for the postwar Ottoman lands.

The Republic of Turkey was established in 1923, with Atatürk as its first president. His government shifted the state away from imperial institutions and toward a republic organized around Turkish national sovereignty. Ankara became the center of the new political order, while Istanbul remained a major city shaped by the Ottoman past. The republic’s founding joined political change to the military and diplomatic achievements of the nationalist movement: independence had been won on the ground, recognized at Lausanne, and given a new constitutional form.

Atatürk founded the Republican People’s Party, known by its Turkish initials CHP, as the principal party of his political project. Secularism and nationalism remained among its defining values, alongside a center-left economic approach. The party’s continued place in electoral politics gave Atatürk’s ideas an institutional life beyond his presidency. Its history also shows that his legacy is argued through ordinary political competition as well as through public ceremonies and national symbols.

Ideology and statements

Atatürk sought to make public authority secular. He curtailed the political power of religious institutions and abolished the Caliphate, one of the last major institutions linking the new republic to the Ottoman religious order. His program aimed to place government under national institutions rather than religious authority. It formed part of a wider attempt to establish a modern republic with a pro-Western orientation. Atatürk expressed an ideal for domestic and international conduct in the phrase “Peace at home, peace in the world.”

The secular program altered everyday religious life as well as the structure of the state. Rules introduced during Atatürk’s presidency prohibited clerical garb outside an exception for heads of autonomous churches. The republic later eased Atatürk-era restrictions on the use of Arabic in the Muslim call to prayer. These policies show the reach of state reform into public practice. After Atatürk’s death, Turkey relaxed many prohibitions introduced during his rule, while retaining the broader debate over secularism and the state.

Atatürk sought equal public treatment for Christianity and Judaism in the new republic. The Treaty of Lausanne secured protections for minority institutions, funds, and schools. Many Jews relinquished foreign nationality and became Turkish citizens, reflecting their commitment to the republic. Yet secular reform did not spare Jewish communal life from restrictions: the prohibition on teaching Hebrew in schools was a serious blow to Turkish Jews. His policies combined a stated principle of equal public treatment with controls whose effects differed across communities.

Hagia Sophia became one of the most visible expressions of Atatürk’s approach. His government designated the building a museum in 1934, opening it to visitors across religious communities and giving it a place in the republic’s secular public life. The decision carried meaning beyond access to a historic building. It represented a change in how the state presented a site associated with successive Christian and Muslim periods of Istanbul’s history. That meaning made its later reversal politically consequential.

Atatürk’s nationalism also shaped Turkey’s account of the settlement it had defeated. Under his rule, Sèvres became a symbol in the official narrative of Ottoman weakness and the need for national resilience. Its significance extended beyond the terms of a treaty that the nationalist government had overturned. The memory of foreign intervention and the struggle for independence became part of the republic’s political language, influencing later arguments about sovereignty and Turkey’s place among other powers.

Role in attacks or conflicts

Atatürk’s central military role was leadership of the Turkish War of Independence. He organized nationalist resistance as foreign armies occupied Ottoman lands and directed a movement that won successive victories. Those victories defeated the effort to impose the Sèvres settlement and established the nationalist government as the force able to determine Turkey’s future. His authority in the republic rested in part on this wartime leadership, which connected the end of the Ottoman Empire to the founding of a new state.

The conflict was military and political at once. The Ottoman government had signed Sèvres, but Mustafa Kemal’s movement rejected its claim to decide the nation’s fate. By presenting itself as Turkey’s exclusive political force, the movement challenged the Sultanate while fighting foreign armies. Abolition of the Sultanate in 1922 removed the imperial institution at the center of that rivalry. The Lausanne settlement in 1923 then recognized the sovereignty that the nationalists had sought through their campaign.

Atatürk’s victory did not erase the wider consequences of the Ottoman collapse. The abolition of the Caliphate in 1924 removed a religious institution with significance beyond Turkey. Four years later, Hassan al-Banna founded the Muslim Brotherhood in Egypt. The end of the Ottoman Caliphate formed part of the political setting in which movements seeking a renewed public role for Islamic institutions developed. Atatürk’s secular republic and those later movements represented sharply different answers to the question of political authority after the empire.

Death or current status

Atatürk died in Istanbul on November 10, 1938, at age 57. He had served as Turkey’s first president from the republic’s establishment in 1923 until his death. His passing ended a presidency that had encompassed independence, the replacement of the Sultanate and Caliphate, and extensive changes to the institutions of public life. Later governments eased a number of restrictions introduced during his rule, but the republic he founded and the questions raised by its secular settlement endured.

Legacy

Atatürk’s legacy remains visible in Turkey’s state institutions, party politics, and public memory. The CHP continues to identify with his secular and nationalist values. In the municipal elections of March 31, 2024, it received 38 percent of the vote and became Turkey’s largest party for the first time since 1977. It retained control of the country’s three largest cities and expanded its success elsewhere. The result demonstrated the continuing electoral strength of a party founded by Atatürk nearly a century earlier.

Public interest in Atatürk also extends beyond party membership. Many young Turks identify politically as Kemalist, expressing attachment to his secular legacy amid continuing debate over religion’s role in government. Record numbers of visitors to his mausoleum provide another measure of that attention. These forms of remembrance do not require agreement with every policy he introduced; they show that the founding president remains a reference point for contemporary arguments about the republic’s identity and direction.

The most prominent contrast in recent politics concerns Erdoğan’s religious policies. Turkey remains constitutionally secular, yet Erdoğan has reshaped the relationship between religion and state. In 2020, he converted Hagia Sophia into a mosque, reversing the museum status established by Atatürk’s government in 1934. The decision was more than a change in the building’s use. For supporters of Erdoğan’s course and opponents of it, the site became a symbol of competing views of Turkey’s history, public religion, and the secular republic.

The contrast has deep roots. Atatürk removed the Caliphate and reduced religious institutions’ political authority as he built a national state. Erdoğan’s approach has given religion a more prominent place in public policy and political identity. The difference between them is a central divide in Turkish politics, although Atatürk’s own legacy includes both the protection promised to minorities at Lausanne and restrictions imposed in the name of reform. Assessing that legacy requires attention to the institutions he founded and to how his policies affected people living under them.

Atatürk’s reputation also crossed Turkey’s borders. After resigning in 1963, David Ben-Gurion praised his leadership and reforms in an article for a Turkish newspaper. More broadly, Atatürk’s transformation of a defeated empire into an independent republic made him a point of reference in discussions of state-building across the Middle East. The lasting significance of his career lies in the conjunction of military independence, recognized sovereignty, secular reform, and a political legacy that remains actively contested within Turkey.
