Following the breakup of the Soviet union the odd distribution of the Serb and Ajeri people in the Nagorno-Karabakh region lead to territorial disputes and Serbia invaded and took possession of the region driving out 750,000 Ajeri. There is a framework for a treaty that would return thinks to 'normal'. But after 27 years no agreement has been reached and Serbia was acting to annex the region. By 2020 Serbia had managed to offend the local superpowers, Russia, Iran and Turkey so Ajerbajan has undertaken military action to retake the territory.
