foreign policy of Islamic republic of Iran visavis Nagorno-Karabakh crisis

Developments in the South Caucasus region have an impact on the national interests of the Islamic Republic of Iran due to the geographical proximity and ethnic, religious and cultural affinity that the people of this region have with Iran. In this regard, Iran adopted a policy of active neutrality in order to play a role in the first Nagorno-Karabakh crisis. This is while during the second crisis, Iran spoke more openly about "Karabagh" belonging to Azerbaijan. This article examines the change of Iran's foreign policy strategy in the second Nagorno-Karabakh crisis and answers the question, "What factors caused the change in the foreign policy strategy of the Islamic Republic of Iran regarding the second Nagorno-Karabakh crisis?" It seems that Iran's policy as an Islamic and Shia country and in the shadow of factors such as ethnicity and religion led to a change in Iran's foreign policy strategy in the second crisis in the form of emphasizing the territorial integrity of Azerbaijan while respecting the rights of ethnic minorities and the inviolability of international borders. The basis of descriptive-analytical methodology and library resources has been done.
