Occupation of Western Armenia

By the Russian Empire during World War I

The occupation of Western Armenia by the Russian Empire during World War I began in 1915 and was formally ended by the Treaty of Brest Litovsk. It was sometimes referred to as the Republic of Van by Armenians. Aram Manukian of the Armenian Revolutionary Federation was the de facto head until July 1915. It was briefly referred to as "Free Vaspurakan". After a setback beginning in August 1915, it was re established in June 1916. The region was allocated to Russia by the Allies in April 1916 under the Sazonov–Paléologue Agreement. From December 1917, it was under Transcaucasian Commissariat, with Hakob Zavriev as the Commissar, and during the early stages of the establishment of First Republic of Armenia, it was included with other Armenian National Councils in a briefly unified Armenia. This provisional government relied on Armenian volunteer units, forming an administrative structure after the siege of Van around April 1915. Dominant representation was from the Armenian Revolutionary Federation. Aram Manukian, or "Aram of Van," was the administration's most famous governor.

During the siege of Van, there were between 67,792 (according to the 1914 Ottoman population estimates) and 185,000 Armenians (according to the Armenian Patriarch's 1912 estimate) in the Van Vilayet. In the city of Van itself there were around 30,000 Armenians, but more Armenians from surrounding villages joined them during the Ottoman offensive.

The conflict began on April 20, 1915, with Aram Manukian as the leader of the resistance, and it lasted for two months. In May, the Armenian battalions and Russian regulars entered the city and drove the Ottoman army out of Van.

The Viceroyalty of the Caucasus was abolished by the Russian Provisional Government on March 18, 1917, and all authority, except in the zone of the active army, was entrusted to the civil administrative body called the Special Transcaucasian Committee, or Ozakom. Hakob Zavriev was instrumental in having Ozakom issue a decree about the administration of the occupied territories. This region was officially identified as "the land of Western Armenia" and transferred to a civilian rule under Zavriev, who oversaw districts Trebizon, Erzurum, Bitlis, and Van.

The Russian army in the Caucasus was organized along national and ethnic lines, such as the Armenian volunteer units and Russian Caucasus Army on the eve of 1917. However, the Russian Caucasus Army disintegrated, leaving Armenian soldiers to become the only defenders against the Ottoman Army. The front line had three main divisions, led respectively by Movses Silikyan, Andranik Ozanian and Mikhail Areshian. Armenian partisan guerrilla detachments accompanied these main units. The Ottomans outnumbered the Armenians three to one on a frontline 300 mile (483 km) long, with high mountain areas and passes.

The chairman of the Van Relief Committee (Near East Relief) was Kostin Hambartsumian, who, taking into consideration the general political situation, conveyed the one thousand five hundred orphans of Children's Home of Van to Gyumri in 1917.

A new border was drawn by the Treaty of Brest Litovsk, signed between Russian SFSR and the Ottoman Empire on March 3, 1918. The treaty assigned the Van Vilayet alongside the Kars Vilayet, Ardahan, and Batum regions to the Ottoman Empire. The treaty also stipulated that Transcaucasia was to be declared independent.

The Armenian Congress of Eastern Armenians (ACEA) representatives on the Duma joined their colleagues in declaring independence of the Transcaucasus from Russia. On April 5, head of the Transcaucasian delegation Akakii Chkhenli accepted the Treaty as a basis for negotiation and wired the governing bodies, urging them to accept this position. The mood prevailing in Tiflis was very different; the treaty did not create a united block. Armenia acknowledged the existence of a state of war with the Ottoman Empire.|R. G. Hovannisian

The Azerbaijani Tatars sided with the Ottoman Empire and seized the lines of communication, cutting off the Armenian National Councils in Baku and Erevan from the National Council in Tbilisi. The British sent a small military force under the command of Gen. Lionel Charles Dunsterville into Baku, arriving on August 4, 1918. On October 30, 1918, the Ottoman Empire signed the Armistice of Mudros, and military activity in the region ceased. Enver Pasha's movement disintegrated with the armistice.

The Treaty of Brest Litovsk, between the Ottoman Empire and Russian SFSR, included the establishment of Armenia in Russian Armenia. The Administration for Western Armenia had a setback with the Treaty of Batum, forcing the Armenian borders to be pushed deeper into Russian Armenia. During the Conference of London, David Lloyd George encouraged American President Woodrow Wilson to accept a mandate for Anatolia, particularly with the support of the Armenian diaspora, for the provinces claimed by the Administration of Western Armenia during its largest occupation in 1916. "Wilsonian Armenia" became part of the Treaty of Sèvres. The realities on the ground, however, were slightly different. The idea was blocked by both the Treaty of Alexandropol and the Treaty of Kars. The Treaty of Sèvres was superseded by the Treaty of Lausanne, and the fight for the "Administration for Western Armenia" was dropped off the table. As a continuation of the initial goal, the creation of a "free, independent, and united" Armenia including all the territories designated as Wilsonian Armenia by the Treaty of Sèvres — as well as the regions of Artsakh and Javakhk— was the main goal of the Armenian Revolutionary Federation.
