During his stay in Sofia the First World War had started and Ottoman Empire had become obliged to enter in this war. Mustafa Kemal was appointed to Tekirdag to organize the 19 Division.
It is in the First World War, which started in 1914, that Mustafa Kemal wrote an heroic epic and made the legend of Dardanelles are Impassable against Entente troops in Gallipoli. On 18 March 1915, when British and French navies failed to break in through Straits of Dardanelles with heavy losses, the decision to land troops on the Gallipoli peninsula had been given. Under the command of Mustafa Kemal, 19 Division halted the enemy forces, which landed in Ariburnu -now called Anzak Koyu (Anzac Cove)- on 25 April 1915 at Conkbayir.

In 1916 after Gallipoli, Mustafa Kemal took duties in Edirne and in Diyarbakir. He was promoted to brigadier general in 1 April 1916. He took part in the battles against Russian forces by which Mus and Bitlis were liberated. After short lasted duties in Damascus and Aleppo, he returned to Istanbul in 1917.

After the beginning of the occupation of the country and demobilization of the Ottoman armies according to the Moudros Truce, Mustafa Kemal arrived in Samsun on 19 May 1919 as the Inspector General of the 9 Army. On 22 June 1919, he issued the Amasya Circular, declaring that Nation's determination and decision will restore the nation's independence and called for the gathering of Congress in Erzurum and Sivas. Between 23 July and 7 August 1919 delegates from all over the country gathered in Erzurum and then between 4-11 September 1919 in Sivas, determining the path to follow in order to gain nations's independence. On 27 December 1919 he was welcomed in Ankara with great enthusiasm. 23 April 1920, the first day of the Turkish Grand National Assembly, is one of the very important steps on the way to founding of the Turkish Republic. Mustafa Kemal was elected as the first Speaker of the House and the Head of the Government. The Turkish Grand National Assembly started preparing and passing the new laws necessary for implementing the Independence War successfully.
Turkish Independence War started by firing the first bullet against the enemy during the occupation of Izmir by the Greek forces on 15 May 1919. Victors of the First World War, by signing of the Sèvres Agreement, started the occupation of their shares of the Ottoman Empire. At the beginning, resistance against occupation forces started with militia forces, namely Kuva-i Milliye (National Forces). Turkish Grand National Assembly established the regular army and successfully led the Independence War to the victory by integrating the militia forces into the regular army.
Important stages of the Independence War under the leadership of Mustafa Kemal are,
Liberation of Sarikamis (20 September 1920), Kars (30 October 1920) and Gümrü (7 November 1920).
Defences of Cukurova, Gaziantep, Sanliurfa and Kahraman Maras (1919-1920).
Victory at the First Battle of Inönü (6-10 January 1920)

Victory at the Battle of Sakarya (23 August-13 September 1921).
Great Offensive, Battle of Dumlupinar (Battle of Commander-in-Chief) and the Great (Final) Victory (26 August-9 September 1922).

After the victory at the Battle of Sakarya, Turkish Grand National Assembly promoted Mustafa Kemal to the rank of Field Marshal and granted him the title of Gazi-the Victorious Fighter. The Independence War ended by Lausanne Peace Treaty on 24 July 1923. Thus, all the impediments of the Sèvres Agreement had been removed and integrity of the Turkish land had been accomplished by the signing of the Lausanne Agreement.

There was no obstructions left on the way to establish the new Turkish State based on national solidarity. Founding of the Turkish Republic had been heralded by the opening of the Turkish Grand National Assembly on 23 April 1920. National Assembly's successful administration during the Independence War had secured the founding of the new Turkish State.
