What do Tensions Between Armenia and Azerbaijan Tell Us About Russia and the CSTO?

On 20 March 2024, Nikol Pashinyan, the current Prime Minister of Armenia told various news outlets that a resurgence of conflict between his own state and neighbouring Azerbaijan was looking increasingly likely. 


Hostilities have raged between the two unfriendly neighbours since the collapse of the Soviet Union in 1991. Following their respective transitions from Soviet republics to independent states, relations between Yerevan and Baku (the two respective capitals) quickly disintegrated. Within the USSR, both territories had ultimately taken their directives from Moscow and had thus been coherent gambits in a much larger geopolitical mass. However, as independent states, the two sides quickly realised there was not much in the way of shared identity to maintain the Soviet era levels of cooperation. Armenia is a majority ethnically Armenian and Orthodox Christian populated country, whilst Azerbaijan is a majority Turkic ethnic state, with the main religion being Islam. 


These differences have been crucial in sparking the series of conflicts which have come to define the relationship between Yerevan and Baku over the past 30+ years. All of these conflicts were primarily focussed on the region of Nagorno-Karabakh, which has also been known as the Republic of Artsakh. I have written an in-depth piece on these conflicts here, which examines the entire background to the conflicts and how territory has been exchanged between the two sides since the end of the USSR.


The TLDR on Nagorno-Karabakh is that it is a territory within the confines of Azerbaijan, that was historically populated by ethnic Armenians. The ethnic Armenians living within Nagorno-Karabakh (with the assistance of Yerevan), declared an independent state within the territory, known as the ‘Republic of Artsakh’. This declaration naturally irritated Azerbaijan, who consistently cited that Nagorno-Karabakh was Azeri territory and should therefore be under the control of Baku. Yerevan’s response was that it was historically Armenian territory which hadn't been accounted for by the Soviet authorities. Essentially, the two sides couldn’t agree and so the first Nagorno-Karabakh War ensued. On this occasion, Armenia was very much the victor, taking the Nagorno-Karabakh region along with some additional Azeri territories to its west in order to create a sizable land bridge between Armenia proper and the Republic of Artsakh.  For 26 years, this remained the status quo and Armenia basqued in its glory of unifying the Armenian population across what it saw as its native territory.
