The Kuva-yi Milliye were irregular Turkish militia forces active in the early period of the Turkish War of Independence. These irregular forces emerged after the occupation of the parts of Turkey by the Allied forces in accordance with the Armistice of Mudros. Later, Kuva-yi Milliye were integrated to the regular army of the Grand National Assembly. Some historians call this period (1918–20) of the Turkish War of Independence the "Kuva-yi Milliye phase".

The Turkish War of Independence was a series of military campaigns and a revolution waged by the Turkish National Movement, after parts of the Ottoman Empire were 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 national self-determination, in post-World War I Anatolia and Eastern Thrace. The revolution concluded the collapse of the Ottoman Empire; the Ottoman monarchy and the Islamic caliphate were abolished, and the Republic of Turkey was declared in Anatolia and Eastern Thrace. This resulted in a transfer of vested sovereignty from the sultan-caliph to the nation, setting the stage for Republican Turkey's period of nationalist revolutionary reform.
