Abolition of the Ottoman sultanate in the context of "Kizlar Agha"

The Turkish War of Independence (15 May 1919 – 24 July 1923) was a series of military campaigns and a revolution waged by the Turkish National Movement, after the Ottoman Empire was occupied and partitioned following its defeat in World War I. The conflict was between the Turkish Nationalists against Allied and separatist forces over the application of Wilsonian principles, especially self-determination, in post-World War I Anatolia and eastern Thrace. The revolution concluded the collapse of the Ottoman Empire and the Eastern question, ending the Ottoman sultanate and the Ottoman caliphate, and establishing the Republic of Turkey. This resulted in the transfer of sovereignty from the sultan-caliph to the nation, setting the stage for nationalist revolutionary reform in Republican Turkey.

While World War I ended for the Ottomans with the Armistice of Mudros, the Allies continued occupying land per the Sykes–Picot Agreement, and to facilitate the prosecution of former members of the Committee of Union and Progress and those involved in the Armenian genocide. Ottoman commanders therefore refused orders from the Allies and Ottoman government to disband their forces. In an atmosphere of turmoil, Sultan Mehmed VI dispatched general Mustafa Kemal Pasha (Atatürk), to restore order; however, he became an enabler and leader of Turkish Nationalist resistance. In an attempt to establish control over the power vacuum in Anatolia, the Allies agreed to launch a Greek peacekeeping force and occupy Smyrna (İzmir), inflaming sectarian tensions and beginning the Turkish War of Independence. A nationalist counter government led by Mustafa Kemal was established in Ankara when it became clear the Ottoman government was appeasing the Allies. The Allies pressured the Ottoman "Istanbul government" to suspend the Constitution, Parliament, and sign the Treaty of Sèvres, a treaty unfavorable to Turkish interests that the "Ankara government" declared illegal.

The Republic of Turkey was created after the overthrow of Sultan Mehmed VI by Mustafa Kemal Atatürk in 1922 by the new Republican Parliament in 1923. This new regime delivered the coup de grâce to the Ottoman state which had been practically wiped away from the world stage following the First World War.

Mustafa Kemal Atatürk (c. 1881 – 10 November 1938) was a Turkish field marshal and statesman who was the founder of the Republic of Turkey, serving as its first president from 1923 until his death in 1938. He undertook sweeping reforms, which modernized Turkey into a secular, industrializing nation. Ideologically a secularist and nationalist, his policies and socio-political theories became known as Kemalism.

Born in Salonica in the Ottoman Empire, his early military career saw him involved in the Italo-Turkish and Balkan Wars. As a member of the Committee of Union and Progress and the Young Turks, he played an important part in political events of the late Ottoman Empire, such as the Young Turk Revolution and the 31 March Incident. He rose to prominence with his role in the Defence of Gallipoli during World War I. Following the defeat of the empire after the war, he led the Turkish National Movement, which resisted the empire's partition among the victorious Allied powers. Establishing the provisional "Ankara government", he defeated the forces sent by the Allies, thus emerging victorious from the Turkish War of Independence. During and after the war, the ethnic cleansing of Armenians and Greeks from Anatolia outside of Istanbul, including the Kars region invaded by the Kemalist armies, was largely completed via large-scale massacres, flight, expulsions, and the population exchange between Greece and Turkey. His government subsequently proceeded to abolish the Ottoman sultanate in 1922 and proclaimed the Republic of Turkey in its place in 1923.

The Turkish National Movement (Turkish: Türk Ulusal Hareketi), also known as the Anatolian Movement (Turkish: Anadolu Hareketi), the Nationalist Movement (Turkish: Milliyetçi Hareket), and the Kemalists (Turkish: Kemalîler, Kemalciler or Kemalistler), included political and military activities of the Turkish revolutionaries that resulted in the creation and shaping of the modern Republic of Turkey, as a consequence of the defeat of the Ottoman Empire in World War I and the subsequent occupation of Constantinople and partitioning of the Ottoman Empire by the Allies under the terms of the Armistice of Mudros. The Turkish revolutionaries rebelled against this partitioning and against the Treaty of Sèvres, signed in 1920 by the Ottoman government. Most revolutionaries were former members of the Committee of Union and Progress.

This establishment of an alliance of Turkish revolutionaries during the partitioning resulted in the Turkish War of Independence, the genocides of the Anatolian native nations, the abolition of the Ottoman sultanate on 1 November 1922 and the declaration of the Republic of Turkey on 29 October 1923. The movement organized itself into the Association for the Defence of National Rights of Anatolia and Rumeli, which eventually declared that the only source of governance for the Turkish people would be the Grand National Assembly of Turkey.

Osmanoğlu family is a family belonging to the historical House of Osman, which was the ruling house of the Ottoman Empire from 1299 until the abolition of the Ottoman sultanate in 1922, and the Ottoman Caliphate from 1517 until the abolition of the caliphate in 1924. In 1924, members of the Osmanoğlu family were forced into exile. Their descendants now live in many countries throughout Europe, as well as in the United States, the Middle East, and since they have been permitted to return to their homeland, many now also live in Turkey. The female members of the dynasty were allowed to return after 1951, and the male members after 1973. The family adopted the surname of Osmanoğlu, meaning "son of Osman".

The sultans of the Ottoman Empire (Turkish: Osmanlı padişahları), who were all members of the Ottoman dynasty (House of Osman), ruled over the transcontinental empire from its perceived inception in 1299 to its dissolution in 1922. At its height, the Ottoman Empire spanned an area from Hungary in the north to Yemen in the south and from Algeria in the west to Iraq in the east. Administered at first from the city of Söğüt since before 1280 and then from the city of Bursa since 1323 or 1324, the empire's capital was moved to Adrianople (now known as Edirne in English) in 1363 following its conquest by Murad I and then to Constantinople (present-day Istanbul) in 1453 following its conquest by Mehmed II.

The Ottoman Empire's early years have been the subject of varying narratives, due to the difficulty of discerning fact from legend. The empire came into existence at the end of the 13th century, and its first ruler (and the namesake of the Empire) was Osman I. According to later, often unreliable Ottoman tradition, Osman was a descendant of the Kayı tribe of the Oghuz Turks. The eponymous Ottoman dynasty he founded endured for six centuries through the reigns of 36 sultans. The Ottoman Empire disappeared as a result of the defeat of the Central Powers, with whom it had allied itself during World War I. The partitioning of the Empire by the victorious Allies and the ensuing Turkish War of Independence led to the abolition of the sultanate in 1922 and the birth of the modern Republic of Turkey in 1922.

The Ottoman Caliphate, the world's last widely recognized caliphate, was abolished on 3 March 1924 (R.C. 1340, A.H. 1342) by decree of the Grand National Assembly of Turkey. The process was one of Atatürk's reforms following the replacement of the Ottoman Empire with the Republic of Turkey. Abdülmecid II was deposed as the last Ottoman caliph.

The caliph was nominally the supreme religious and political leader of all Sunni Muslims across the world. In the years prior to the abolition, during the ongoing Turkish War of Independence, the uncertain future of the caliphate provoked strong reactions among the worldwide community of Sunni Muslims. The potential abolition of the caliphate had been actively opposed by the Indian-based Khilafat Movement, and generated heated debate throughout the Muslim world. The 1924 abolition came about less than 18 months after the abolition of the Ottoman sultanate, prior to which the Ottoman sultan was ex officio caliph.

Mustafa Kemal Atatürk (c. 1881 – 10 November 1938) was a Turkish field marshal and statesman who was the founder of the Republic of Turkey —after the fall of its predecessor, the Ottoman Empire— and served as its first president from 1923 until his death in 1938. He led sweeping reforms, which modernized Turkey into a secular, industrializing nation. Ideologically a secularist and nationalist, his policies and socio-political theories became known as Kemalism. Atatürk's personality cult and the Kemalist historiography developed around it have had significant and ongoing influences on Turkey's political culture and historical narrative.
