Historical pictues: Turkish War of Independence & Mustafa Kemal Atatürk

The Turkish War of Independence (Turkish: Kurtuluş Savaşı "War of Liberation", also known figuratively as İstiklâl Harbi "Independence War" or Millî Mücadele "National Campaign"; 19 May 1919 – 24 July 1923) was fought between the Turkish National Movement and the proxies of the Allies – namely Greece on the Western front, Armenia on the Eastern, France on the Southern and with them, the United Kingdom and Italy in Constantinople (now Istanbul) – after parts of the Ottoman Empire were occupied and partitioned following the Ottomans' defeat in World War I.[43][44][45] Few of the occupying British, French, and Italian troops had been deployed or engaged in combat.

The Turkish National Movement (Kuva-yi Milliye) in Anatolia culminated in the formation of a new Grand National Assembly (GNA; Turkish: BMM) by Mustafa Kemal Atatürk and his colleagues. After the end of the Turkish–Armenian, Franco-Turkish, Greco-Turkish fronts (often referred to as the Eastern Front, the Southern Front, and the Western Front of the war, respectively), the Treaty of Sèvres was abandoned and the Treaties of Kars (October 1921) and Lausanne (July 1923) were signed. The Allies left Anatolia and Eastern Thrace, and the Grand National Assembly of Turkey decided on the establishment of a Republic in Turkey, which was declared on 29 October 1923.

With the establishment of the Turkish National Movement, the partitioning of the Ottoman Empire, and the abolition of the sultanate, the Ottoman era and the Empire came to an end, and with Atatürk's reforms, the Turks created the modern, secular nation-state of Turkey on the political front. On 3 March 1924, the Ottoman caliphate was officially abolished and the last Caliph was exiled.
