Lachin and the villages of Sus and Zabukh were returned under Azerbaijan's control on August 26, 2022, as part of the 2020 ceasefire agreement.

[9] The reputed author Movses Kaghankatvatsi mentions a so-called Berdzor horse purportedly indigenous to the region, as does Makar Barkhudaryan, an Apostolic bishop, traveler, polymath, and ethnographer from Shusha.

[10] During the medieval period, the town Berdzor was mentioned as being a part of the Artsakh province within the domain of the Armenian Bagratid Kingdom.

[11] Jalal al-Din Mangburni's private secretary Shihab ad-Din an-Nasawi referred to the settlement as both Berdadzor and a new name, Kaladara.

[20][16] In the early 1920s, Vladimir Lenin's letter to Nariman Narimanov "had implied that Lachin was to be included in Azerbaijan, but the authorities in Baku and Yerevan were given promises that were inevitably contradictory.

[3] According to journalist Onnik Krikorian, although the official statistics claimed that the number of Armenian residents in Lachin was 2200, the actual figure was around 50% less.

While some settlers were refugees from Azerbaijan and Karabakh, as well as from the diaspora, Krikorian wrote that most were poor families from Armenia, attracted by the promise of land, livestock and social benefits that averaged 4,000 Armenian drams (about ten US dollars) per child.

[26] The OSCE Minsk Group co-chairs had noted that "Lachin has been treated as a separate case in previous negotiations."

[27] On June 16, 2015, the European Court of Human Rights passed a judgement in the case of Chiragov and Others v. Armenia, which concerned the complaints by six Azerbaijani ethnically-Kurdish refugees that they were unable to return to their homes and property in the district of Lachin, in Azerbaijan, from where they had been forced to flee in 1992 during the Armenian-Azerbaijani conflict over Nagorno-Karabakh.

The Court confirmed that Armenia exercised effective control over Nagorno-Karabakh and the surrounding territories and thus had de facto jurisdiction over the district of Lachin.

On August 2, the local Armenian authorities reported that the Azerbaijani side had conveyed to them a demand to organise communication with Armenia along a different route, bypassing the existing one.

On August 4, the Minister of Territorial Administration and Infrastructure of Armenia, Gnel Sanosyan, stated that the construction of an alternative road to Lachin was actively underway and would be completed the spring of 2023.

[5] In May 2024, satellite imagery showed that the Armenian church of St. Ascension had been completely demolished by the Azerbaijani government, with no trace of it left.
