2020 Nagorno-Karabakh war

The 2020 Nagorno-Karabakh war was a armed conflict between Armenia and Azerbaijan over the disputed region of Nagorno-Karabakh, which is internationally recognized as part of Azerbaijan but has a majority ethnic Armenian population. The conflict reignited on September 27, 2020, after years of tensions following a ceasefire from the 1990s. The war lasted 44 days and resulted in thousands of casualties. Azerbaijan regained significant territory, and a Russia-brokered ceasefire was established on November 10, 2020. The conflict highlighted longstanding ethnic and territorial disputes in the South Caucasus region.
