Peacekeeping operations in Nagorno-Karabakh in the context of "Stepanakert"

On 19 and 20 September 2023, Azerbaijan launched a large-scale military offensive against the self-declared breakaway state of Artsakh, violating the ceasefire agreement signed in the aftermath of the Second Nagorno-Karabakh War in 2020. The offensive took place in the disputed region of Nagorno-Karabakh, which is de jure a part of Azerbaijan, and was a de facto independent republic. The stated goal of the offensive was the complete disarmament and unconditional surrender of Artsakh, as well as the withdrawal of all ethnic Armenian soldiers present in the region. The offensive occurred in the midst of an escalating crisis caused by Azerbaijan's 10-month-long blockade of Artsakh, which resulted in significant scarcities of essential supplies such as food, medicine, and other goods.

One day after the offensive started on 20 September, a ceasefire agreement described as a written agreement for the surrender of Artsakh was reached at the mediation of the Russian peacekeeping contingent where it was agreed that the Artsakh Defence Army would be disarmed. Ceasefire violations by Azerbaijan were nonetheless reported by both Artsakhi residents and officials until early October. On 28 September, the president of Artsakh, Samvel Shahramanyan signed a decree to dissolve all state institutions by 1 January 2024, bringing the existence of the breakaway state to an end.

The Armenian political crisis started in 2020 with the Azerbaijani offensive against the self-declared Republic of Artsakh which triggered mass protests in Armenia. The crisis escalated after the Russian peacekeeping force were not involved in the third war leaving Armenia isolated. The war ended with the flight of more than 100,000 Armenians from Nagorno-Karabakh. There had been multiple coup plots during the crisis. As of December 2023, parts of Armenia remains under Azerbaijani occupation.

Since the 2020 Nagorno-Karabakh War and the 2023 Flight of Nagorno-Karabakh Armenians, Nikol Pashinyan's approval rating has plummeted from 82 percent in August 2018 to 11.5 percent as of 6 May 2025, one of the lowest approval ratings of any world leader.

On 20 September 2023 a ceasefire agreement ending the Azerbaijani military offensive against the self-proclaimed ethnic Armenian Republic of Artsakh in Nagorno-Karabakh was reached. The agreement was brokered by the Russian peacekeeping contingent stationed in the region since the Second Nagorno-Karabakh War in 2020. Under the terms of the agreement, the Artsakh Defence Army was disbanded. The Russian peacekeepers sheltered at their base camp 2,261 people, of whom 1,049 were children.
