Bilateral relations between modern-day Armenia and the Russian Federation were established on 3 April 1992, though Russia has been an important actor in Armenia since the early 19th century.
The two countries' historic relationship has its roots in the Russo-Persian War of 1826 to 1828 between the Russian Empire and Qajar Persia after which Eastern Armenia was ceded to Russia.
Moreover, Russia was viewed as a protector of the Christian subjects in the Ottoman Empire, including the Armenians.

After the dissolution of the Soviet Union, Armenia has shared Russia's approach aimed at strengthening the Commonwealth of Independent States (CIS).
Armenia and Russia are both members of a military alliance, the Collective Security Treaty Organization (CSTO), along with four other ex-Soviet countries, a relationship that Armenia finds essential to its security.
Among the contracts and the agreements, which determine intergovernmental relations – a treaty of friendship, collaboration and mutual aid of 29 August 1997 are a number of the documents, which regulate bases of Russian military units and liaisons in the Republic of Armenia.
Armenia became a full member of the Eurasian Economic Union on 2 January 2015.
