Information: - Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries. - The Free City of Danzig was a semi-autonomous city-state that existed between 1920 and 1939, consisting of the Baltic Sea port of Danzig (now Gdask, Poland) and nearly 200 towns in the surrounding areas. It was created on 15 November 1920 in accordance with the terms of Article 100 (Section XI of Part III) of the 1919 Treaty of Versailles after the end of World War I. - The final battles of the European Theatre of World War II as well as the German surrender to the Soviet Union and the Western Allies took place in late April and early May 1945. - Nazi Germany is the common English name for the period in German history from 1933 to 1945, when Germany was governed by a dictatorship under the control of Adolf Hitler and the Nazi Party (NSDAP). Under Hitler's rule, Germany was transformed into a fascist state in which the Nazi Party took totalitarian control over nearly all aspects of life. The official name of the state was "Deutsches Reich" from 1933 to 1943 and "Grodeutsches Reich" ("Greater German Reich") from 1943 to 1945. The period is also known under the names the Third Reich and the National Socialist Period (abbreviated as "NS-Zeit").

It originates in the southern Ural Mountains and ends at the Caspian Sea. At , it is the third-longest river in Europe after the Volga and the Danube, and the 18th-longest river in Asia. The Ural River is conventionally considered part of the boundary between the continents of Europe and Asia. - The MolotovRibbentrop Pact, also known as the NaziSoviet Pact or the GermanSoviet Non-aggression Pact (officially: "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. - World WarII (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World WarII the deadliest conflict in human history. - The Invasion of Poland, also known as the September Campaign, or the 1939 Defensive War in Poland (or "Wojna obronna 1939 roku"), and alternatively the Poland Campaign or "Fall Weiss" in Germany (Case White), was a joint invasion of Poland by Nazi Germany, the Free City of Danzig, the Soviet Union, and a small Slovak contingent, that marked the beginning of World War II in Europe. The German invasion began on 1 September 1939, one week after the signing of the MolotovRibbentrop Pact, while the Soviet invasion commenced on 17 September following the Molotov-Tg agreement that terminated the Russian and Japanese hostilities in the east on 16 September. The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German-Soviet Frontier Treaty. - Victory in Europe Day, generally known as V-E Day, VE Day or simply V Day was the public holiday celebrated on 8 May 1945 to mark the formal acceptance by the Allies of World War II of Nazi Germany's unconditional surrender of its armed forces. It thus marked the end of World War II in Europe. - The European Theatre of World War II , also known as the European War , was a huge area of heavy fighting across Europe , from Germany 's and the Soviet Union 's joint invasion of Poland in September 1939 until the end of the war with the Soviet Union conquering much of Europe along with the German unconditional surrender on May 8 , 1945 ( Victory in Europe Day ) . The Allied forces fought the Axis powers on two major fronts ( the Eastern Front and Western Front ) as well as in the adjoining Mediterranean and Middle East Theatre . - The Allies of World War II, called the United Nations from the 1 January 1942 declaration, were the countries that together opposed the Axis powers during the Second World War (19391945). The Allies promoted the alliance as seeking to stop German, Japanese and Italian aggression. - The Soviet Union, officially the Union of Soviet Socialist Republics (USSR " ) was a socialist state in Eurasia that existed from 1922 to 1991.

More than 70million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. - An unconditional surrender is a surrender in which no guarantees are given to the surrendering party. In modern times, unconditional surrenders most often include guarantees provided by international law. Announcing that only unconditional surrender is acceptable puts psychological pressure on a weaker adversary, but may also prolong hostilities. Perhaps the most notable unconditional surrender was by the Axis powers in World War II.
