Nagorno-Karabakh war: History
The conflict between Azerbaijan and Armenia over the Nagorno-Karabakh region began in 1988, when the predominantly Armenian-populated Nagorno-Karabakh Autonomous Oblast announced its withdrawal from the Azerbaijan Soviet Socialist Republic.
In 1991-1994, the bloodshed conflict continued in the region, which ended with the signing of a ceasefire protocol. Nagorno-Karabakh proclaimed itself an independent "republic." Azerbaijan did not recognize this, considering the territory to have been occupied by Armenia.
