Armenian resistance during the Armenian genocide in the context of "Musa Dagh"

The Armenian genocide was the systematic destruction of the Armenian people and identity in the Ottoman Empire during World War I. Spearheaded by the ruling Committee of Union and Progress (CUP), it was implemented primarily through the mass murder of around one million Armenians during death marches to the Syrian Desert and the forced Islamization of others, primarily women and children.

Before World War I, Armenians occupied a somewhat protected, but subordinate, place in Ottoman society. Large-scale massacres of Armenians had occurred in the 1890s and 1909. The Ottoman Empire suffered a series of military defeats and territorial losses, especially during the 1912–1913 Balkan Wars. This sparked fear among CUP leaders that the Armenians, whose homeland in Anatolia they considered the Turkish nation's last refuge, would seek independence. During their invasion of Russian and Persian territory in 1914, Ottoman paramilitaries massacred local Armenians. Ottoman leaders took isolated instances of Armenian resistance as evidence of a widespread rebellion, and decided to permanently forestall the possibility of Armenian autonomy or independence.

The Middle Eastern theatre of World War I saw action between 30 October 1914 and 30 October 1918. The combatants were, on one side, the Ottoman Empire (including the majority of Kurdish tribes and Circassians, and the relative majority of Arabs), with some assistance from the other Central Powers; and on the other side, the British (with the help of a small number of Jews, Greeks, Armenians, some Kurdish tribes and Arab states, along with Hindu, Sikh and Muslim colonial troops from India) as well as troops from the British Dominions of Australia, Canada, and New Zealand, the Russians (with the help of Armenians, Assyrians, and occasionally some Kurdish tribes), and the French (with its North African and West African Muslim, Christian and other colonial troops) from among the Allied Powers. There were four main campaigns: the Sinai and Palestine, Mesopotamian, Caucasus, and Gallipoli campaigns. There were four more minor campaigns in Persia, South Arabia, the Arabian interior, and Libya.

Both sides used local asymmetrical forces in the region. On the Allied side were Arabs who participated in the Arab Revolt and the Armenian militia who participated in the Armenian resistance supported by Russia during the War; along with Armenian volunteer units, the Armenian militia formed the Armenian Corps of the First Republic of Armenia in 1918. In addition, the Assyrians joined the Allies and saw action in Southeastern Turkey, northern Mesopotamia (Iraq), northwestern Iran and northeastern Syria following the Assyrian genocide, instigating the Assyrian war of independence. Turks were persecuted by the invading Russian troops in the east and by Greek troops and Armenian fedayis in the west, east, and south of Anatolia. The theatre covered the largest territory of all theatres in the war.
