The significant part of the territory currently belonging to Armenia was incorporated into the Russian Empire pursuant to the 1828 Treaty of Turkmenchay signed between Russia and Persia following the Russo-Persian War (1826–28).

After the 1917 Russian Revolution, Armenia gained short-lived independence as the First Republic of Armenia.
By 1920, the state was incorporated into the Transcaucasian Socialist Federative Soviet Republic, a founding member of the Soviet Union that was formally constituted in 1922.
In 1936, the Transcaucasian state was dissolved, leaving its constituent states, including the Armenian Soviet Socialist Republic, as full Union republics.

The modern Armenia became independent in 1991 as a consequence of the dissolution of the Soviet Union due to the failed coup that happened in August.
Armenia boycotted the union-wide preservation vote earlier that year.

The Russian Federation, the successor state of the Soviet Union, is believed to have been instrumental in achieving victory by Armenians in the Nagorno-Karabakh War (1988–1994).
In 2013, the deputy prime-minister of Azerbaijan Ali S. Hasanov said, "We need to become much stronger so that if we become involved in combat in Nagorno-Karabakh we can stand up to Russian troops, because that is who we will have to face.
Did Armenia occupy our territories?
Do you think Armenia's power is sufficient for that?”
