Many abandoned towns and settlements in the former Soviet Union were established near Gulag labour camps to supply necessary services. The 1950s saw the abandonment of most of these camps, which in turn led to the abandonment of the towns. One such town is located near the former Gulag camp called Butugychag (also called Lower Butugychag). Other towns were deserted due to deindustrialisation and the economic crises of the early 1990s attributed to post-Soviet conflicts—one example being Tkvarcheli in Georgia, a coal mining town that suffered a drastic population decline as a result of the War in Abkhazia in the early 1990s, and Aghdam, made ruined and uninhabited after the First Nagorno-Karabakh War.[citation needed]
