evidence: While reporting from the South Caucasus has recently focused on Azerbaijan’s victory in the Nagorno-Karabakh conflict, it is important to recognise the renewed importance of the Nakhchivan region. This autonomous republic is quickly becoming a key part of regional politics. [...] A little-known autonomous republic within Azerbaijan is another consequence of the Stalinist regime’s policy of "divide and conquer". Having regained control of Nagorno-Karabakh, Baku has not hesitated to express its desire for a direct link with its exclave Nakhchivan, an intention that complicates relations with the EU and western partners. [...] However, the Soviets held a referendum in 1921, in which 90 per cent of the Nakhchivan population voted to remain part of the Azerbaijani SSR. The result was confirmed by the treaty of March 16th 1921 between Turkey and Soviet Russia. From 1924, it became an autonomous republic within the Azerbaijani SSR. During the Soviet period, the region’s Azerbaijani population continued to grow steadily, while the Armenian minority decreased from 15 per cent in 1926 to 1.4 per cent in 1979.
