The Continuation War, also known as the Second Soviet-Finnish War, was a conflict fought by Finland and Nazi Germany against the Soviet Union during World War II. It began with a Finnish declaration of war and invasion on 25 June 1941 and ended on 19 September 1944 with the Moscow Armistice. The Soviet Union and Finland had previously fought the Winter War from 1939 to 1940, which ended with the Soviet failure to conquer Finland and the Moscow Peace Treaty. Numerous reasons have been proposed for the Finnish decision to invade, with regaining territory lost during the Winter War regarded as the most common. Other justifications for the conflict include Finnish President Risto Ryti's vision of a Greater Finland and Commander-in-Chief Carl Gustaf Emil Mannerheim's desire to annex East Karelia.
The Molotov–Ribbentrop Pact, officially the Treaty of Non-Aggression between Germany and the Union of Soviet Socialist Republics, was a non-aggression pact between Nazi Germany and the Soviet Union with a secret protocol that partitioned Central and Eastern Europe between them. The pact was signed in Moscow on 23 August 1939 by German Foreign Minister Joachim von Ribbentrop and Soviet Foreign Minister Vyacheslav Molotov. Unofficially, it has also been referred to as the Hitler–Stalin Pact, Nazi–Soviet Pact, or Nazi–Soviet Alliance.
Operation Barbarossa was the invasion of the Soviet Union by Nazi Germany and many of its Axis allies, starting on Sunday, 22 June 1941, during the Second World War. It was the largest land offensive in human history, with around 10 million combatants taking part. The operation, code-named after Frederick Barbarossa, a 12th-century Holy Roman Emperor and Crusader, put into action Nazi Germany's ideological goal of conquering the western Soviet Union to repopulate it with Germans. The German Generalplan Ost aimed to use some of the conquered people as forced labour for the Axis war effort while acquiring the oil reserves of the Caucasus as well as the agricultural resources of various Soviet territories, including Ukraine and Byelorussia. Their ultimate goal was to create more Lebensraum for Germany, and the eventual extermination of the native Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide.
The Axis powers, originally called the Rome–Berlin Axis, was a military coalition that initiated World War II and fought against the Allies. Its principal members were Nazi Germany, the Kingdom of Italy, and the Empire of Japan. The Axis were united in their far-right positions and general opposition to the Allies, but otherwise lacked comparable coordination and ideological cohesion.
Co-belligerence is the waging of a war in cooperation against a common enemy with or without a military alliance. Generally, the term is used for cases where no formal treaty of alliance exists. Likewise, allies may not become co-belligerents in a war if a casus foederis invoking the alliance has not arisen. Co-belligerents are defined in the Encyclopaedic Dictionary of International Law as "states engaged in a conflict with a common enemy, whether in alliance with each other or not".
The Finnish Army is the land forces branch of the Finnish Defence Forces. The Finnish Army is divided into six branches: the infantry, field artillery, anti-aircraft artillery, engineers, signals, and materiel troops. The commander of the Finnish Army since 1 January 2022 is Lieutenant General Pasi Välimäki.
The European theatre of World War II was one of the two main theatres of combat during World War II. It saw heavy fighting across Europe for almost six years, starting with Germany's invasion of Poland on 1 September 1939 and ending with the Western Allies conquering most of Western Europe, the Soviet Union conquering most of Eastern Europe including the German capital Berlin, and Germany's unconditional surrender on 8 May 1945 although fighting continued elsewhere in Europe until 25 May. On 5 June 1945, the Berlin Declaration proclaiming the unconditional surrender of Germany to the four victorious powers was signed. The Allied powers fought the Axis powers on two major fronts, but there were other fronts varying in scale from the Italian campaign, to the Polish Campaign, as well as in a strategic bombing offensive and in the adjoining Mediterranean and Middle East theatre.
Operation Alphabet was an evacuation, authorised on 24 May 1940, of Allied troops from the harbour of Narvik in northern Norway marking the success of Operation Weserübung and the end of the Allied campaign in Norway during World War II. The evacuation was completed by 8 June.
The 169th Infantry Division was a German military unit during World War II.
Finland participated in the Second World War initially in a defensive war against the Soviet Union, followed by another, this time offensive, war against the Soviet Union acting in concert with Nazi Germany and then finally fighting alongside the Allies against Germany.
The matter of German troop transfer through Finland and Sweden during World War II was one of the more controversial aspects of modern Nordic history beside Finland's co-belligerence with Nazi Germany in the Continuation War, and the export of Swedish iron ore during World War II.
The Ryti–Ribbentrop letter of agreement was a personal letter from President of Finland Risto Ryti to German Führer Adolf Hitler signed on 26 June 1944. It was sent during the Soviet Vyborg–Petrozavodsk Offensive, which had started on 9 June and threatened to knock Finland out of the Continuation War.
The 163rd Infantry Division was a German Army infantry division in World War II. Formed in November 1939, it was engaged in the invasion of Norway the following year. It fought alongside the Finnish Army during Operation Barbarossa against the Soviet Union. During this time, the division's transit through neutral Sweden caused the Midsummer Crisis of 1941. The division spent most of the war in Finland, before being returned to Germany. It was destroyed in March 1945 in Pomerania by the First Polish Army, subordinated to the Soviet 1st Belorussian Front.
The history of the Jews in Finland goes back to the 1700s. The country is home to some 1,800 Jews, of which 1,400 live in the Greater Helsinki area and 200 in Turku. Most Jews in Finland have Finnish or Swedish as their mother tongue, and many speak Yiddish, German, Russian and Hebrew. Jews originally came to Finland as Russian soldiers who stayed in Finland in the 19th century after their military service ended. There are Jewish congregations in Helsinki and Turku with their own synagogues built in 1906 and 1912. The Wiborg Synagogue built 1910–1911 was destroyed in air bombings during the first day of the Winter War in 30 November 1939. Since data collection began in 2008, incidents of antisemitism have been on the rise in Finland. The number of incidents are likely under-reported as Finland does not account for specific forms of hate speech that incite violence or hatred.
The Erna long-range reconnaissance group was a Finnish Army unit of Estonian volunteers that fulfilled reconnaissance duties in Estonia behind Red Army lines during World War II. The unit was formed by Finnish military intelligence with the assistance of German military intelligence for reconnaissance operations.

The timeline of the occupation of the Baltic states lists key events in the military occupation of the three countries – Estonia, Latvia and Lithuania – by the Soviet Union and by Nazi Germany during World War II.
The foreign relations of Third Reich were characterized by the territorial expansionist ambitions of Germany's dictator Adolf Hitler and the promotion of the ideologies of anti-communism and antisemitism within Germany and its conquered territories. The Nazi regime oversaw Germany's rise as a militarist world power from the state of humiliation and disempowerment it had experienced following its defeat in World War I. From the late 1930s to its defeat in 1945, Germany was the most formidable of the Axis powers - a military alliance between Imperial Japan, Fascist Italy, and their allies and puppet states.
The Hitler and Mannerheim recording is a 1942 recording of a private conversation between German dictator Adolf Hitler, and Carl Gustaf Emil Mannerheim, Commander-in-Chief of the Finnish Defence Forces. It took place on a secret visit made to Finland by Hitler to honour Mannerheim's 75th birthday on 4 June 1942, during the Continuation War, a sub-theatre of World War II. Thor Damen, a sound engineer for the Finnish broadcaster Yleisradio (YLE) who had been assigned to record the official birthday proceedings, recorded the first eleven minutes of Hitler and Mannerheim's private conversation—without Hitler's knowledge. It is the only known recording of Hitler speaking in an unofficial tone.
