The Battle of Marash (Turkish: Maraş Muharebesi), also called the "Marash Affair", was a battle that took place in the early winter of 1920 between the French forces occupying the city of Maraş in the Ottoman Empire and the Turkish National Forces linked to Mustafa Kemal Atatürk. It was the first major battle of the Turkish War of Independence, and the three-week-long engagement in the city ultimately forced the French to abandon and retreat from Marash and resulted in a Turkish massacre of Armenian refugees who had just been repatriated to the city following the Armenian Genocide.
