The Battle for Zangezur[a] was a prolonged military conflict fought between June 1920 and July 1921 for control of the strategic and rugged region of Zangezur (Syunik). The war was waged between Armenian national forces, initially part of the First Republic of Armenia and later organized as the Republic of Mountainous Armenia, and the Soviet Red Army supported by forces from Soviet Azerbaijan and Turkish nationalists.

The conflict is historically significant for ensuring that the Zangezur region remained an integral part of Armenia rather than being annexed by Soviet Azerbaijan. Led by the military commander Garegin Nzhdeh, the Armenian resistance transformed Zangezur into the last bastion of Armenian independence after the fall of the central government in Yerevan in December 1920.
Background
Following the sovietization of Azerbaijan in April 1920, the 11th Red Army took up positions along the frontiers of the Armenian republic.[4]: 45 The Soviet leadership in Moscow, while engaged in negotiations with the Armenian mission led by Levon Shant, authorized the Red Army to occupy the "disputed" territories of Karabagh, Zangezur, and Nakhichevan.[4]: 45, 65 For the Soviets, control of these regions was vital to opening a strategic land corridor to their ally, the Turkish Nationalist movement of Mustafa Kemal Pasha.[4]: 128, 250
Soviet invasion
In June 1920, the Red Army's 32nd Rifle Division began its advance into Zangezur. Despite local Armenian protests, a Soviet scouting party entered the village of Tegh on June 29, and by July 5, the Red Army occupied Goris, the administrative center of the district.[4]: 66–67
The initial period of Soviet occupation was marked by political repression. The Cheka (extraordinary committee) carried out numerous arrests of Armenian nationalists and socialist opponents. In early August, the Red Army executed prominent Armenian figures, including Parliament members Arshak Shirinian and Vahan Khoreni, whose bodies were discovered with signs of torture.[4]: 85–86
On August 10, 1920, the Armenian government in Yerevan, pressured by the simultaneous Turkish invasion on its western front, signed a preliminary treaty in Tiflis. This accord gave the Armenian government's "temporary" consent to the Soviet occupation of Zangezur and Karabagh, hoping to stabilize relations with Moscow while focusing on the Turkish threat.[4]: 93–96
Nzhdeh's revolt
While regular Armenian army units under Dro withdrew to Daralagiaz following the August treaty, Garegin Nzhdeh refused to abandon the region. He retreated to his stronghold on Mount Khustup in the Ghapan district, vowing to resist the Bolshevik-Turkish alignment.[4]: 108–109 On August 25, 1920, Nzhdeh was proclaimed Sparapet (Supreme Commander) by his partisans in the village of Kavart.[4]: 110
Exploiting the local population's resentment toward Bolshevik requisitions and the murder of their leaders, Nzhdeh launched a general rebellion on October 10. His irregulars utilized explosive-filled barrels rolled down mountain slopes and their intimate knowledge of the terrain to devastate Soviet columns.[4]: 111, 116
Confrontation in Goris
General Nikifor Nesterovskii and later General Petr (Pyotr) Kuryshko led massive operations to liquidate the rebellion.[4]: 116, 119 However, in a series of engagements during November 1920, Nzhdeh's forces routed the Red Army’s 28th Division. By November 22, 1920, Nzhdeh’s forces triumphantly re-entered Goris, expelling the Red Army from Zangezur.[4]: 121–122
The sovietization of the central Armenian government in Yerevan occurred on December 2, 1920.[4]: 386–388 Zangezur, however, remained independent under Nzhdeh's control, declaring itself "Autonomous Siunik." Following the failed February Uprising of 1921 in Yerevan, thousands of Armenian soldiers, intellectuals, and political leaders fled to Zangezur to continue the resistance.[4]: 404–405
On April 26, 1921, at a congress held in Tatev, the Republic of Mountainous Armenia was proclaimed. Nzhdeh served as the supreme military commander, while Simon Vratsian headed the civil administration.[4]: 405 The republic continued to demand that Zangezur remain an integral part of Armenia, citing the declaration made by Soviet Azerbaijan's leader, Nariman Narimanov, on November 30, 1920, which had briefly ceded the disputed regions to Armenia as a "fraternal gesture".[4]: 380–383
Final Soviet offensive
Aftermath and legacy
The Soviet central government in Yerevan, now led by the more moderate Alexander Miasnikian, offered a general amnesty to the rebels and provided firm guarantees that Zangezur would remain part of the Armenian Soviet Socialist Republic rather than being ceded to Azerbaijan.[4]: 406 Realizing that further resistance would be futile—as their goal of incorporating Zangezur into Soviet Armenia had been achieved—the leaders of Mountainous Armenia crossed the Araxes River into Persia on July 16, 1921, ending the war.[4]: 406
Historians generally credit the resistance of Mountainous Armenia with ensuring Zangezur's incorporation into the Armenian state. While neighboring Karabakh and Nakhchivan were assigned to Soviet Azerbaijan, the prolonged conflict in Zangezur led Soviet authorities to guarantee the region's permanence within Soviet Armenia as a condition to end the rebellion.[4]: 407
