Identify the Border dispute that is most closely related to the breakup of Soviet Union

Answer 1

The most closely related border dispute to the breakup of the Soviet Union is the conflict over Nagorno-Karabakh. Nagorno-Karabakh is a region within Azerbaijan with a predominantly ethnic Armenian population. As the Soviet Union began to dissolve in the late 1980s and early 1990s, tensions between Azerbaijan and Armenia over the status of Nagorno-Karabakh escalated into a full-scale war, leading to the deaths of thousands of people and the displacement of hundreds of thousands more. This conflict was one of the many ethnic and territorial disputes that emerged as the Soviet Union disintegrated, ultimately contributing to its collapse.
