This war is going on over a mountainous area called Nagorno-Karabakh. Azerbaijan claims that the area is its own, although the region has been occupied by Armenia since the 1992 war. Historically, this region has been dominated by separatist organizations. This led to several decades of ethnic conflicts. This dispute between the two countries is several decades old. From the early 1980s to 1992, there was a war between the two countries over the region. During that time more than 30 thousand people were killed and more than one million people were displaced. Even after the ceasefire in 1994, there were frequent reports of violence. Both these countries agreed to a ceasefire but never consented to a peace agreement.
