Azerbaijan and Armenia have been engaged in a conflict over Nagorno-Karabakh for decades. In the nineties, the region, inhabited mainly by Armenians, was able to break away from Azerbaijan in a bloody civil war.
In 2020, Baku regained control of part of the area after new fighting over a ceasefire agreement. Many Armenians find the terms of the ceasefire, in which Yerevan renounced parts, humiliating. According to observers, a complete abandonment of the region is likely to provoke new unrest in Armenia.
