Committee of Union and Progress in the context of "National Security Service (Turkey)"

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 Albanian revolt of 1912 (Albanian: Kryengritja e vitit 1912, "Uprising of 1912") was the last revolt against the Ottoman Empire's rule in Albania and lasted from January until August 1912. The revolt ended when the Ottoman government agreed to fulfill the rebels' demands on 4 September 1912. Generally, Muslim Albanians fought against the Ottomans then governed by the Committee of Union and Progress.

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.

The Republican People's Party (Turkish: Cumhuriyet Halk Partisi [dʒumhuːɾiˈjet haɫk 'paɾtisi] , CHP [dʒeːheːpeˑ]) is a Kemalist and social democratic political party in Turkey. It is the oldest political party in Turkey, founded by Mustafa Kemal Atatürk, the first president and founder of the modern Republic of Türkiye. The party is also cited as the founding party of modern Turkey. Its logo consists of the Six Arrows, which represent the foundational principles of Kemalism: republicanism, reformism, laicism, populism, nationalism, and statism. It is currently the second largest party in Grand National Assembly with 139 MPs, behind the ruling conservative Justice and Development Party (AKP).

The political party has its origins in the various resistance groups founded during the Turkish War of Independence, with most members being previously associated with the Committee of Union and Progress. Under the leadership of Mustafa Kemal Atatürk, they united in the 1919 Sivas Congress. In 1923, the "People's Party", soon adding the word "Republican" to its name, declared itself to be a political organisation and announced the establishment of the Turkish Republic, with Atatürk as its first president. As Turkey moved into its authoritarian one-party period, the CHP was the apparatus of implementing far reaching political, cultural, social, and economic reforms in the country.

Hussein bin Ali al-Hashimi (Arabic: ٱلْحُسَيْن بِن عَلِي ٱلْهَاشِمِي, romanized: al-Ḥusayn bin 'Alī al-Hāshimī pronunciation; 1 May 1854 – 4 June 1931) was a Hejazi leader from the Banu Qatadah branch of the Banu Hashim clan who was the Sharif and Emir of Mecca from 1908 and, after proclaiming the Great Arab Revolt against the Ottoman Empire, King of the Hejaz, even if he refused this title, from 1916 to 1924. He proclaimed himself Caliph after the abolition of the Ottoman Caliphate in 1924 and stayed in power until 1925 when Hejaz was invaded by the Sultanate of Nejd. His Caliphate was opposed by the British and French empires, the Zionists and the Wahhabis alike. However, he received support from a large part of the Muslim population of that time and from Mehmed VI. He is usually considered as the father of modern pan-Arabism.

In 1908, in the aftermath of the Young Turk Revolution, Hussein was appointed Sharif of Mecca by the Ottoman sultan Abdul Hamid II. His relationship with the Ottoman government deteriorated after the Committee of Union and Progress took power, particularly because of their policies of Turkification and persecution of ethnic minorities, including Arabs. In 1916, with the promise of British support for Arab independence, although it is debated as to what extent the British were influential in his choice, he proclaimed the Arab Revolt against the Ottoman Empire, accusing the Committee of Union and Progress of violating tenets of Islam and limiting the power of the sultan-caliph. While his armies, led by his sons, were engaged in fighting the Ottoman and German troops in the Middle East, Hussein supported the Armenians during the Armenian genocide and saved up to 4,000 of them. In the aftermath of World War I, Hussein refused to ratify the Treaty of Versailles, in protest of the Balfour Declaration, a document supporting the Jewish settlers in Palestine, and the establishment of British and French mandates in Syria, Iraq, and Palestine. His sons Faisal and Abdullah were made rulers of Iraq and Transjordan respectively in 1921.

The Armenian genocide was the systematic destruction of the Armenian people and identity in the Ottoman Empire during World War I. Spearheaded by the ruling Committee of Union and Progress (CUP), it was implemented primarily through the mass murder of around one million Armenians during death marches to the Syrian Desert and the forced Islamization of others, primarily women and children.

Before World War I, Armenians occupied a somewhat protected, but subordinate, place in Ottoman society. Large-scale massacres of Armenians had occurred in the 1890s and 1909. The Ottoman Empire suffered a series of military defeats and territorial losses, especially during the 1912–1913 Balkan Wars. This sparked fear among CUP leaders that the Armenians, whose homeland in Anatolia they considered the Turkish nation's last refuge, would seek independence. During their invasion of Russian and Persian territory in 1914, Ottoman paramilitaries massacred local Armenians. Ottoman leaders took isolated instances of Armenian resistance as evidence of a widespread rebellion, and decided to permanently forestall the possibility of Armenian autonomy or independence.

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.
