Lachin (Azerbaijani: Laçın, Kurdish: Laçîn) is a rayon of Azerbaijan. The capital is the city of Lachin. The region has been controlled by the breakway Nagorno-Karabakh Republic, as part of its Qashatagh Province, since the Nagorno-Karabakh War.
Upon the capture of Lachin rayon, Armenian forces forcefully displaced its entire Azeri and Kurdish population and resettled the region with Armenian refugees from Azerbaijan, settlers from Armenia and ethnic Armenians from other countries apparently with promises of land, livestock and social benefits. The main land-link between Armenia and the Nagorno-Karabakh Republic, known as the Lachin corridor, crosses its territory. The Lachin Kurdish Republic was briefly proclaimed in 1992 during the Nagorno-Karabakh War for Kurdish inhabitants.
In the first half of 2011, 300 Armenian families were settled in Lachin
