Armenia–Azerbaijan relations

There are currently no diplomatic relations between Armenia and Azerbaijan, though both countries committed to a peace agreement on 8 August 2025. The two neighboring states had formal governmental relations between 1918 and 1921, during their brief independence from the collapsed Russian Empire, as the First Republic of Armenia and the Democratic Republic of Azerbaijan; these relations existed from the period after the Russian Revolution until they were occupied and annexed by the Soviet Union, becoming the constituent republics of Soviet Armenia and Soviet Azerbaijan. Due to the five wars waged by the countries in the past century—one from 1918 to 1921, another from 1988 to 1994, and the most recent in 2016, 2020 and 2023—the two countries have had strained and largely hostile relations. Azerbaijan has continued to enforce a blockade of Armenia since 1989. Social memory of Soviet-era cohabitation is widely repressed through censorship, stigmatization, and government policies that promote mutually hostile sentiment.
