Answer:
Several areas of the former Soviet Union have experienced violent conflicts in the years since the dissolution of the Soviet Union in 1991. Some of the most notable areas include:
Chechnya: Located in the North Caucasus region of Russia, Chechnya has been the site of two wars (1994-1996 and 1999-2009) between Russian forces and Chechen separatists seeking independence. The conflict has resulted in tens of thousands of deaths and displacement of hundreds of thousands of people.
Nagorno-Karabakh: This region is a disputed territory between Azerbaijan and Armenia. Following the collapse of the Soviet Union, conflict erupted between the two countries over control of Nagorno-Karabakh, which has a majority Armenian population but is internationally recognized as part of Azerbaijan. A ceasefire was declared in 1994, but sporadic violence has continued to erupt in the region.
Abkhazia and South Ossetia: These two regions are located in Georgia and have declared independence from the country, but their sovereignty is not internationally recognized. Both regions experienced violent conflicts in the early 1990s and again in 2008, when Russia intervened on behalf of the separatists.
Transnistria: This region is a self-proclaimed republic located in Moldova. It declared independence in 1990, leading to a brief conflict with Moldova. The dispute has not been resolved, and Transnistria remains unrecognized by the international community.
Crimea: This region was part of Ukraine but was annexed by Russia in 2014, leading to a conflict between Ukraine and Russia that continues to this day.
There have also been other areas within the former Soviet Union that have experienced lower-level conflicts and tensions, such as the Ferghana Valley in Central Asia and the Russian-speaking regions of Ukraine.
