The Molotov–Ribbentrop Pact,officially the Treaty of Non-Aggression between Germany and the Union of Soviet Socialist Republics,[1][2] and also known as the Hitler–Stalin Pact[3][4] and the Nazi–Soviet Pact,[5] was a non-aggression pact between Nazi Germany and the Soviet Union, with a secret protocol establishing Soviet and German spheres of influence across Eastern Europe.[6]
The pact was signed in Moscow on 24 August 1939 (backdated 23 August 1939) by Soviet Foreign Minister Vyacheslav Molotov and German Foreign Minister Joachim von Ribbentrop.[7]
The treaty was the culmination of negotiations around the 1938–1939 deal discussions, after tripartite discussions with the Soviet Union, the United Kingdom and France had broken down, and committed neither government would aid or ally itself with an enemy of the other, for the next 10 years. Under the Secret Protocol, Poland was to be shared, while Lithuania, Latvia, Estonia, Finland and Bessarabia went to the Soviet Union.
The protocol also recognized the interest of Lithuania in the Vilnius region. In the west, rumoured existence of the Secret Protocol was proven only when it was made public during the Nuremberg trials.[8]
A week after signing the pact, on 1 September 1939, Germany invaded Poland.
On 17 September, one day after a Soviet–Japanese ceasefire came into effect after the Battles of Khalkhin Gol,[9] and one day after the Supreme Soviet of the Soviet Union approved the Molotov–Ribbentrop Pact,[10]
Stalin, stating concern for ethnic Ukrainians and Belarusians in Poland, ordered the Soviet invasion of Poland. After a short war ending in military defeat for Poland, Germany and the Soviet Union drew up a new border between them on formerly Polish territory in the supplementary protocol of the German–Soviet Boundary and Friendship Treaty.
In March 1940, parts of the Karelia, and eastern parts of Salla and Kuusamo regions as well, in Finland were annexed by the Soviet Union following the Winter War.
The Soviet annexation of Estonia, Latvia, Lithuania and parts of Romania (Bessarabia, Northern Bukovina and the Hertsa region) followed.
Stalin's invasion of Bukovina in 1940 violated the pact, since it went beyond the Soviet sphere of influence that had been agreed with the Axis.[11]
The territories of Poland annexed by the Soviet Union following the 1939 Soviet invasion east of the Curzon line remained in the Soviet Union after the war and are now in Ukraine and Belarus.
Vilnius was given to Lithuania. Only Podlaskie and a small part of Galicia east of the San River, around Przemyśl, were returned to Poland.
Of all the other territories annexed by the Soviet Union in 1939–1940, those detached from Finland (Western Karelia, Hanko) Estonia (Estonian Ingria and Petseri County) and Latvia (Abrene) remain part of Russia, the successor state to the Russian SFSR and the Soviet Union after the collapse of the USSR in 1991.
The territories annexed from Romania were also integrated into the Soviet Union (such as the Moldavian SSR, or oblasts of the Ukrainian SSR). The core of Bessarabia now forms Moldova.
Northern Bessarabia, Northern Bukovina and the Hertsa region now form the Chernivtsi Oblast of Ukraine. Southern Bessarabia is part of the Odessa Oblast, which is also now in Ukraine.
The pact was terminated on 22 June 1941, when Germany launched Operation Barbarossa and invaded the Soviet Union, in pursuit of the ideological goal of Lebensraum.[12]

The Anglo-Soviet Agreement succeeded it. After the war, Ribbentrop was convicted of war crimes at the Nuremberg trials and executed in 1946, whilst Molotov died in 1986.
