caption_attribution_description: English: Liberation of Istanbul on October 6, 1923
context_page_description: The occupation of Constantinople, the capital of the Ottoman Empire, by British, French, Italian, Greek, American and Japanese forces, took place in accordance with the Armistice of Mudros, which ended Ottoman participation in the First World War. The first French troops entered the city on November 12, 1918, followed by British troops the next day. The Italian troops landed in Galata on February 7, 1919.
  Allied troops occupied zones based on the sections of Constantinople and set up an Allied military administration early in December 1918. The occupation had two stages: the initial phase in accordance with the Armistice gave way in 1920 to a more formal arrangement under the Treaty of Sèvres. Ultimately, the Treaty of Lausanne, signed on 24 July 1923, led to the end of the occupation. The last troops of the Allies departed from the city on 4 October 1923, and the first troops of the Ankara government, commanded by Şükrü Naili Pasha, entered the city with a ceremony on 6 October 1923, which has been marked as the Liberation Day of Istanbul and is commemorated every year on its anniversary.
  1918 saw the first time the city had changed hands since the Fall of Constantinople in 1453.
context_section_description: The success of the Turkish National Movement against the French and Greeks was followed by their forces threatening the Allied forces at Chanak. The British decided to resist any attempt to penetrate the neutral zone of the Straits. Kemal was persuaded by the French to order his forces to avoid any incident at Chanak. Nevertheless, the Chanak Crisis nearly resulted in hostilities, these being avoided on October 11, 1922, when the Armistice of Mudanya was signed, bringing the Turkish War of Independence to an end.  The handling of this crisis caused the collapse of David Lloyd George's Ministry on October 19, 1922.
  Following the Turkish War of Independence (1919–1922), the Grand National Assembly of Turkey in Ankara abolished the Sultanate on 1 November 1922, and the last Ottoman Sultan, Mehmed VI, was expelled from the city. Leaving aboard the British warship HMS Malaya on 17 November 1922, he went into exile and died in Sanremo, Italy, on 16 May 1926.
  Negotiations for a new peace treaty with Turkey began at the Conference of Lausanne on 20 November 1922 and reopened after a break on 23 April 1923. This led to the signing of the Treaty of Lausanne on July 24, 1923. Under the terms of the treaty, Allied forces started evacuating Constantinople on 23 August 1923 and completed the task on 4 October 1923 – British, Italian, and French troops departing pari passu.
  Turkish forces of the Ankara government, commanded by Şükrü Naili Pasha (3rd Corps), entered the city with a ceremony on 6 October 1923, which has been marked as the Liberation Day of Istanbul (Turkish: İstanbul'un Kurtuluşu) and is commemorated every year on its anniversary. On 29 October 1923 the Grand National Assembly of Turkey declared the establishment of the Turkish Republic, with Ankara as its capital. Mustafa Kemal Atatürk became the Republic's first President.
