History

The village was located in the Armenian-occupied territories surrounding Nagorno-Karabakh, coming under the control of ethnic Armenian forces during the First Nagorno-Karabakh War in the early 1990s. The village subsequently became part of the self-proclaimed Republic of Artsakh as part of its Kashatagh Province. It was returned to Azerbaijan as part of the 2020 Nagorno-Karabakh ceasefire agreement.
