The defense of Van was the armed resistance of the Armenian population of Van against the Ottoman Empire's attempts to massacre the Ottoman Armenian population of the Van Vilayet in the 1915 Armenian genocide. Several contemporaneous observers and later historians have concluded that the Ottoman government deliberately instigated an armed Armenian resistance in the city and then used this insurgency as the main pretext to justify beginning the deportation and slaughter of Armenians throughout the empire. Witness reports agree that the Armenian posture at Van was defensive and an act of resistance to massacre. The self-defense action is frequently cited in Armenian genocide denial literature; it has become "the alpha and omega of the plea of ‘military necessity’" to excuse the genocide and portray the persecution of Armenians as justified.

The Battle of Kara Killisse, also known as the Battle of Malazgirt, was a battle on the Caucasus front in July 1915 after the Battle of Manzikert. In Russian historical literature, this engagement is considered as a part of "Alashkert defensive operation". Previously in the summer of 1915 the Russians attacked Turkish positions northeast of lake Van but they underestimated the size of their enemy. They were defeated at the Battle of Manzikert. This success encouraged the Turks under Abdul Kerim Pasha to advance towards the Russians in the Eleşkirt valley while the Turks were pursuing the remnants of Oganovki's army across the Ağrı mountains they spread out and Russian general Yudenich took the opportunity to counterattack from the west with some 20.000 reinforcements mostly Cossack units to encircle them. in the following battles between 5–8 August the Turks retreated south but the Russians succeeded only partially. The Turks lost some guns, large provisions and 10.000 killed and wounded and 6.000 became prisoners. Due to difficulties the Russians could not gain total advantage and retreated from the town of Van and Turks occupied it on 3 August.

The Persian campaign or invasion of Iran was a series of military conflicts between the Ottoman Empire and the British Empire and Russian Empire in the Iranian Azerbaijan region of neutral Qajar Iran, beginning in December 1914 and ending with the Armistice of Mudros on 30 October 1918, as part of Middle Eastern theatre of World War I. The fighting also involved local Persian units, who fought against both the Entente and Ottoman forces in Iran. Collectively, the conflict proved to be a devastating experience for Persia. Over 2 million Persian civilians died in the conflict, mostly due to the Ottoman-perpetrated genocide and famine of 1917–1919, itself influenced by British and Russian actions. The Qajar government's inability to maintain the country's sovereignty during and immediately after the First World War led to a coup d'état in 1921 and Reza Shah's establishment of the Pahlavi dynasty.

The Battle of Sardarabad was a battle of the Caucasus campaign of World War I that took place near Sardarabad, Armenia, from 21 to 29 May 1918, between the regular Armenian military units and militia on one side and the Ottoman army that had invaded Eastern Armenia on the other. As Sardarabad is approximately 40 kilometres (25 mi) west of the capital of Yerevan, the battle not only halted the Ottoman advance into the rest of Armenia, but also prevented the complete destruction of the Armenian nation. In the words of Christopher J. Walker, had the Armenians lost this battle, "it is perfectly possible that the word Armenia would have henceforth denoted only an antique geographical term".
