 During the Armenian patriotic movement of the late 19th century, the Ottoman Muslims of Eastern Asia Minor, who happened to be mostly Kurdish and Turkish, were the main enemies of the Armenian patriots.The formation of the Armenian patriotic movement began roughly around the end of the Russo-Turkish War of 1878 and intensified with the introduction of Article 166 of the Ottoman Penal Code and the raid of Erzerum Cathedral.Article 166 was meant to control the possession of arms, but was used to target Armenians by restricting their possession of arms.
