In the 1920s, the Soviet government established the Nagorno-Karabakh Autonomous Region—where 95 percent of the population is ethnically Armenian—within Azerbaijan. Under Bolshevik rule, fighting between the two countries was kept in check, but, as the Soviet Union began to collapse, so did its grip on Armenia and Azerbaijan. In 1988, the Nagorno-Karabakh legislature passed a resolution to join Armenia despite the region's legal location within Azerbaijan’s borders. As the Soviet Union was dissolving in 1991, the autonomous region officially declared independence. War erupted between Armenia and Azerbaijan over the region, leaving roughly thirty thousand casualties and hundreds of thousands of refugees. By 1993, Armenia controlled Nagorno-Karabakh and occupied 20 percent of the surrounding Azerbaijani territory. In 1994, Russia brokered a cease-fire which has remained in place since.
