|Timelines of World War II|
This is a timeline of events that stretched over the period of World War II . For events preceding September 1, 1939, see the timeline of events preceding World War II.
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. It included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, and the only use of nuclear weapons in war.
This timeline of events preceding World War II covers the events of the interwar period (1918–1939) after World War I that affected or led to World War II.
The Molotov–Ribbentrop Pact, officially known as the Treaty of Non-aggression between Germany and the Union of Soviet Socialist Republics, was a neutrality pact between Nazi Germany and the Soviet Union signed in Moscow on 23 August 1939 by foreign ministers Joachim von Ribbentrop and Vyacheslav Molotov, respectively.
The Winter War was a military conflict between the Soviet Union (USSR) and Finland. It began with a Soviet invasion of Finland on 30 November 1939, three months after the outbreak of World War II, and ended three and a half months later with the Moscow Peace Treaty on 13 March 1940. The League of Nations deemed the attack illegal and expelled the Soviet Union from the organisation.
German–Soviet Union relations date to the aftermath of the First World War. The Treaty of Brest-Litovsk, dictated by Germany ended hostilities between Russia and Germany; it was signed on March 3, 1918. A few months later, the German ambassador to Moscow, Wilhelm von Mirbach, was shot dead by Russian Left Socialist-Revolutionaries in an attempt to incite a new war between Russia and Germany. The entire Soviet embassy under Adolph Joffe was deported from Germany on November 6, 1918, for their active support of the German Revolution. Karl Radek also illegally supported communist subversive activities in Weimar Germany in 1919.
The Soviet invasion of Poland was a military operation by the Soviet Union without a formal declaration of war. On 17 September 1939, the Soviet Union invaded Poland from the east, sixteen days after Germany invaded Poland from the west. Subsequent military operations lasted for the following 20 days and ended on 6 October 1939 with the two-way division and annexation of the entire territory of the Second Polish Republic by Germany and the Soviet Union. The Soviet invasion of Poland was secretly approved by Germany following the signing of the Molotov–Ribbentrop Pact on 23 August 1939.
The Soviet occupation of Latvia in 1940 refers, according to the European Court of Human Rights, the Government of Latvia, the United States Department of State, and the European Union, to the military occupation of the Republic of Latvia by the Soviet Union ostensibly under the provisions of the 1939 Molotov–Ribbentrop Pact with Nazi Germany.
This is a timeline of events that stretched over the period of World War II.
The Soviet–Lithuanian Mutual Assistance Treaty was a bilateral treaty signed between the Soviet Union and Lithuania on October 10, 1939. According to provisions outlined in the treaty, Lithuania would acquire about one fifth of the Vilnius Region, including Lithuania's historical capital, Vilnius, and in exchange would allow five Soviet military bases with 20,000 troops to be established across Lithuania. In essence the treaty with Lithuania was very similar to the treaties that the Soviet Union signed with Estonia on September 28, and with Latvia on October 5. According to official Soviet sources, the Soviet military was strengthening the defenses of a weak nation against possible attacks by Nazi Germany. The treaty provided that Lithuania's sovereignty would not be affected. However, in reality the treaty opened the door for the first Soviet occupation of Lithuania and was described by The New York Times as "virtual sacrifice of independence."
The Molotov–Ribbentrop Pact was an August 23, 1939, agreement between the Soviet Union and Nazi Germany colloquially named after Soviet foreign minister Vyacheslav Molotov and German foreign minister Joachim von Ribbentrop. The treaty renounced warfare between the two countries. In addition to stipulations of non-aggression, the treaty included a secret protocol dividing several eastern European countries between the parties.
In October and November 1940, German–Soviet Axis talks occurred concerning the Soviet Union's potential entry as a fourth Axis Power in World War II. The negotiations, which occurred during the era of the Molotov–Ribbentrop Pact, included a two-day Berlin conference between Soviet Foreign Minister Vyacheslav Molotov, Adolf Hitler and German Foreign Minister Joachim von Ribbentrop, followed by both countries trading written proposed agreements. After two days of negotiations from 12 to 14 November 1940, Germany presented the Soviets with a draft written Axis pact agreement defining the world spheres of influence of the four proposed Axis powers. Hitler, Ribbentrop and Molotov tried to set German and Soviet spheres of influence; Hitler encouraged Molotov to look south to Iran and eventually India while preserving German access to Finland's resources, and to remove Soviet influence in the Balkans. Molotov remained firm, seeking to remove German troops from Finland and gain a warm water port in the Balkans. Soviet foreign policy calculations were predicated by the idea that the war would be a long-term struggle and therefore German claims that Britain would be defeated swiftly were treated with skepticism. In addition, Stalin sought to remain influential in Bulgaria and Yugoslavia. These factors resulted in Molotov taking a firm line. According to a Columbia University academical source, on 25 November 1940, the Soviets presented a Stalin-drafted written counterproposal where they would accept the four power pact, but it included Soviet rights to Bulgaria and a world sphere of influence centered on the area around Iraq and Iran. Germany did not respond, leaving the negotiations unresolved. Regarding the counterproposal, Hitler remarked to his top military chiefs that Stalin "demands more and more", "he's a cold-blooded blackmailer" and that "a German victory has become unbearable for Russia" so that "she must be brought to her knees as soon as possible." Germany broke the Molotov–Ribbentrop Pact in June 1941 by invading the Soviet Union.
Relevant events began regarding the Baltic states and the Soviet Union when, following Bolshevist Russia's conflict with the Baltic states—Lithuania, Latvia and Estonia—several peace treaties were signed with Russia and its successor, the Soviet Union. In the late 1920s and early 1930s, the Soviet Union and all three Baltic States further signed non-aggression treaties. The Soviet Union also confirmed that it would adhere to the Kellogg–Briand Pact with regard to its neighbors, including Estonia and Latvia, and entered into a convention defining "aggression" that included all three Baltic countries.
Timeline of the occupation of the Baltic States lists key events in the military occupation of the Baltic states of Estonia, Latvia, and Lithuania by the Soviet Union and by Nazi Germany during World War II.
The background of the Winter War covers the period before the outbreak of the Winter War between Finland and the Soviet Union in 1939–1940, stretching from the Finnish Declaration of Independence in 1917 to the Soviet-Finnish negotiations in 1938–1939. Before its independence, Finland was an autonomous grand duchy inside Imperial Russia. During the ensuing Finnish Civil War, the Red Guards, supported by the Russian Bolsheviks, were defeated. Fearful of Soviet designs, during the 1920s and 1930s, the Finns were constantly attempting to align themselves with Scandinavian neutrality, particularly with regard to Sweden. Furthermore, the Finns engaged in secret military co-operation with Estonia in the 1930s.
The timeline of the Winter War is a chronology of events leading up to, culminating in, and resulting from the Winter War. The war began when the Soviet Union attacked Finland on 30 November 1939 and it ended 13 March 1940.
The timeline of the Molotov–Ribbentrop Pact is a chronology of events, including Molotov–Ribbentrop Pact negotiations, leading up to, culminating in, and resulting from the Molotov–Ribbentrop Pact. The Treaty of Non-aggression between Nazi Germany and the Soviet Union was signed in the early hours of August 24, 1939, but was dated August 23.
The background of the occupation of the Baltic states covers the period before the first Soviet occupation on 14 June 1940, stretching from independence in 1918 to the Soviet ultimatums in 1939–1940. The Baltic states gained their independence during and after the Russian revolutions of 1917; Lenin's government allowed them to secede. They managed to sign non-aggression treaties in the 1920s and 1930s. Despite the treaties, the Baltic states were forcibly incorporated into the Soviet Union in 1940 in the aftermath of the German–Soviet pact of 1939.
The Soviet occupation of the Baltic states covers the period from the Soviet–Baltic mutual assistance pacts in 1939, to their invasion and annexation in 1940, to the mass deportations of 1941.
The Soviet Union occupied most of the territory of the Baltic states in its 1944 Baltic Offensive during World War II. The Red Army regained control over the three Baltic capitals and encircled retreating Wehrmacht and Latvian forces in the Courland Pocket where they held out until the final German surrender at the end of the war. The German forces were deported and the leaders of Latvian collaborating forces were executed as traitors. After the war, the Soviet Union reestablished control over the Baltic territories in line with its forcible annexations as communist republics in 1940.
The Soviet–Estonian Mutual Assistance Treaty, also known as the Bases Treaty was a bilateral treaty signed in Moscow on 28 September 1939. The treaty obliged both parties to respect each other's sovereignty and independence, and allowed the Soviet government to establish military bases in Estonia. These bases facilitated the Soviet takeover of the country in June 1940.
The Soviet–Latvian Mutual Assistance Treaty was a bilateral treaty signed in Moscow on October 5, 1939. The treaty obliged both parties to respect each other's sovereignty and independence, while in practice allowed the Soviet government to establish military bases in Latvia, which facilitated the Soviet invasion of that country in June 1940.
