First Nagorno-Karabakh War
The First Nagorno-Karabakh War was a war that had happened since February 1988 until May 1994, over the small ethnic enclave of Nagorno-Karabakh in southwestern Azerbaijan, between the mostly ethnic Armenians of Nagorno-Karabakh backed by Armenia and Azerbaijan. The war originates from 1918, when the World War I came to an end and the Ottoman Empire collapsed into independent states including Armenia and Azerbaijan, while the region was recognized as part of Azerbaijan. Since then, Armenia has claimed it; Armenians have made many efforts to unify the region, although Azerbaijanis also have worked to protect their sovereignty as well as national identity.
