Diplomatic relations between the regions that now constitute Romania and the Russian Federation date back to the
medieval period. The
Tsardom of Russia offered support for the
Danubian Principalities during their struggle for independence from the
Ottoman Empire.
Moldavian ruler
Stephen the Great concluded a military-political alliance with Russia in the fifteenth century, sealed by the marriage of his daughter
Elena to
Ivan the Young, the son and heir of
Ivan III.
Wallachian ruler
Michael the Brave also advocated an alliance with Russia towards the end of the sixteenth century. Relations continued to be strengthened after the establishment of the
Russian Empire, with the 1711
Treaty of Lutsk between
Peter the Great and Moldovan leader
Dimitrie Cantemir; and the establishment of permanent diplomatic relations between Wallachia and Russia during the 1688-1714 reign of
Constantin Brâncoveanu. Relations were once more suspended on 22 June 1941 after the
Axis invasion of the Soviet Union, and remained so during most of the Second World War. During the
Cold War Romania was a member of the
Warsaw Pact, and with the
dissolution of the Soviet Union at the end of 1991, the Russian Federation emerged as the Soviet Union's legal successor. The incumbent ambassador of the Soviet Union to Romania, , continued as representative of Russia until 1992. ==List of representatives (1878–present) ==
