Armenian-controlled territories surrounding Nagorno-Karabakh
The Armenian-controlled territories surrounding Nagorno-Karabakh are areas formally part of Soviet Azerbaijan and situated outside the former Nagorno-Karabakh Autonomous Oblast, which are since the end of the Karabakh War controlled by the military forces of Nagorno-Karabakh Republic supported by Armenia.
These areas have also been referred to as:
- Seven occupied territories of Azerbaijan surrounding Nagorno-Karabakh 
- Security belt of the Nagorno-Karabakh Republic
- Buffer zone of the Nagorno-Karabakh Republic
- Liberated areas of Nagorno-Karabakh 
- Kelbajar - (1,936 km2, 100% of which is controlled by the Defense Army of Nagorno-Karabakh Republic),
- Lachin - (1,835 km2. - 100%),
- Kubatli - (802 km2. - 100%),
- Jebrail - (1,050 km2. - 100%),
- Zangelan - (707 km2. - 100%),
- Agdam - (1,094 km2. - 77% (842 km2)),
- Fuzuli - (1,386 km2. - 33% - 462 km2.)
At the outset of the Karabakh conflict, the Nagorno-Karabakh Autonomous Oblast / Nagorno-Karabakh Republic was surrounded by regions with Azerbaijani, Kurdish but also minority Armenian population and had no land border with Armenia. During the Nagorno-Karabakh war Azerbaijan had subjected Nagorno-Karabakh to a total blockade, which resulted in famine. As reported by the Human Rights Watch, "By the winter of 1991-92, as a result of Azerbaijan's three-year economic and transport blockade, Nagorno-Karabakh was without fuel…, electricity, running water, functioning sanitation facilities, communication facilities and most consumer goods." In 1992 the United States Congress added Section 907 to the Freedom Support Act of 1992, which banned direct US government support to the government of Azerbaijan. The bill namely stated:
United States assistance under this or any other Act may not be provided to the Government of Azerbaijan until the President determines that the Government of Azerbaijan is taking demonstrable steps to cease all blockades and other offensive uses of force against Armenia and Nagorno-Karabakh.
- 18 May 1992, Armenian forces took Lachin, opening the Lachin corridor for land communications between NKR and Armenia. However, the corridor was under constant threat from Azerbaijani forces who repeatedly tried to cut it. A strong offensive by Armenian forces occurred in 1993, resulting in the securing of further territory to act as a "security zone".
- 27 March 1993, Armenian forces launched an offensive in Kelbajar and by 5 April had completely captured the area of Kalbajar Rayon, creating a strong link between Nagorno Karabakh and Armenia and removing from the Lachin corridor the threat of attack from the north.
- 23 July 1993, after 40 days of fighting, officially known in Armenia as the "suppression of enemy firing points", Agdam was taken. Then followed attack in the south:
- 22 August 1993 Fizuli was taken.
- 25 August 1993 - Jebrail was taken.
- 31 August 1993 - Kubatly was taken.
- 1 November 1993 - Zangelan was taken.
During this phase of the war Azerbaijan would not agree to sign a ceasefire until after these territories passed under the Armenian control and there was a danger that Armenians would advance further to take territories of vital importance for Azerbaijan. As described by Russian mediator Vladimir Kazimirov,
Azerbaijan for too long a time was counting on military solution of the problem… those who for more than a year (1993-1994) ignored the UN Resolutions that called for the ceasefire… were supposed to realise their direct responsibility for the consequences – for the loss of more regions and the increasing the number of refugees and IDPs.
Since then, Armenians have been in control of most of the territory of the former Nagorno-Karabakh Autonomous Oblast, except for parts of east Martuni and east Martakert. In addition, since that time Armenians have controlled all of the territory between the former NKAO to Iran, as well as all of the territory between the former NKAO and Armenia, and some areas to the east surrounding Aghdam. In the north, however, the NKR also claims but does not control the region known until 1992 as [Shahumian]]. That was not a part of the former NKAO, though it did have a substantial Armenian population - driven out in 1992. The Armenian and Azeri forces have been separated on the northern front by the Murovdag mountain chain ever since.
Since 1994, Armenia and Azerbaijan have held talks on the future of the security belt territories. The Nagorno-Karabakh Republic has not been involved in these negotiations because Azerbaijan does not recognize the existence of such parties to the conflict. The Armenian side has offered to act in accordance with the "land for status" formula (returning the territory of the security belt to the control of Azerbaijan in exchange for Azerbaijan recognising the independence of Nagorno-Karabakh Republic and giving security assurances to the Nagorno-Karabakh Republic and the Lachin corridor), Azerbaijan, on a formula of "land for peace" (returning the territory of the security belt back to Azerbaijan in exchange for security guarantees with Azerbaijan controlling territories of Nagorno-Karabakh). Facilitators have also offered, in particular, another "land for status" option (returning the territory of the security belt to the control of Azerbaijan in exchange for guarantees by Azerbaijan to hold at some point a referendum on the status of Nagorno-Karabakh). As of 2013, the involved parties have failed to reach any agreement.
- From the standpoint of the Nagorno-Karabakh Republic, the security belt is territory of Azerbaijan temporarily controlled by the Nagorno-Karabakh Defense Army until the receipt of security guarantees for the Nagorno-Karabakh Republic and the establishment of control over the whole of the territory declared by Nagorno-Karabakh Republic, with the exception of the Lachin corridor linking Nagorno-Karabakh Republic with Armenia (which the Nagorno-Karabakh Republic has stated it does not intend to return because of its strategic importance)  (currently Azerbaijan controls 750 km2 of territory claimed by the Nagorno Karabakh Republic - Shahumian (630 square kilometers) and a small part of Martuni and Mardakert areas, representing 14.85% of the total area of NKR). According to Article 142 of the Constitution of Nagorno-Karabakh republic "to restore the integrity of national territory of Nagorno-Karabakh Republic and clarifying boundaries public power is exercised in the territory actually under the jurisdiction of the Nagorno-Karabakh Republic", that is, including the territory of Azerbaijan, outside the former Nagorno-Karabakh Autonomous Oblast and Shaumian district, which borders was proclaimed Republic of Nagorno-Karabakh.
- From the standpoint of Azerbaijan, Nagorno-Karabakh and 7 adjacent districts are a territory occupied by Armenia.
- In the documents of international organizations (such as the United Nations, Parliamentary Assembly of the Council of Europe, Organization for Security and Co-operation in Europe), these areas are also considered as occupied by "Armenian forces", but there are recognized two entities on the Armenian side of the conflict: The Republic of Armenia and "Armenians of Nagorno-Karabakh region of Azerbaijan" (in terms of PACE - "Separatist forces").
Armenian historical monuments
The Armenians rely on and insist on the term "liberated territories," mainly because of the Armenian historical and religious monuments and a constant presence of Armenian population since 350BC that demonstrate along with their cultural monuments a historical presence for centuries, and Armenian population that inhabited these territories in the past. It is noteworthy that prior to 1700's there are literally no evidence of Azerbaijani or Tartar or Turkish cultural monuments in the NKR, the oldest surviving Mosque being built in about 1760AD which is listed in the relevant websites of the Azerbaijan government
There the following cultural, historical and religious monuments of note in these territories:
- Dadivank Monastery, (Armenian: Դադիվանք) - an Armenian monastery in the Shahumian Region (former Kelbajar), built between the 9th and 13th centuries. The monastery was founded by St. Dadi, a disciple of Thaddeus the Apostle who spread Christianity in Eastern Armenia during the first century A.C. In June, 2007, the grave of St. Dadi was discovered under the holy altar of the main church.
- Tzitzernavank Monastery, (Armenian: Ծիծեռնավանք), a fifth- to sixth-century Armenian church and former monastery. The monastery is within five kilometers of the border of Armenia's province of Syunik. The basilica of Tzitzernavank was believed to contain relics of St. George the Dragon-Slayer. In the past, the monastery belonged to the Tatev diocese and is mentioned as a notable religious center by the 13th century historian Stepanos Orbelian and Bishop Tovma Vanandetsi (1655).
- Handaberd, (Armenian: Հանդաբերդ): Armenian castle and fortress, built in the 11th century, that belonged to the rulers of the Kingdom of Upper Khachen and the Kingdom of Tzar., 
- Tigranakert, (Armenian: Տիգրանակերտ) - ruins of an ancient Armenian city near the borders of NKR's Mardakert district, dating back to the Hellenistic period. It is one of several cities on the Armenian plateau named Tigranakert in honor of the Armenian king Tigranes the Great (r. 95–55 B.C.). Tigranakert was uncovered during the excavations which began in 2005.
