Who is engaged in territorial conflict with Armenia?

Armenia is primarily engaged in territorial conflict with Azerbaijan over the disputed region of Nagorno-Karabakh. This conflict has its roots in ethnic and political tensions between Armenians and Azerbaijanis dating back to the early 20th century. Tensions escalated into full-scale wars, notably in the late 1980s and early 1990s, and again in 2020, leading to significant territorial changes and ongoing disputes. The situation remains complex and fragile, with intermittent clashes and diplomatic efforts for resolution.
