Blitzkrieg or bewegungskrieg is a word used to describe a combined arms surprise attack using a rapid, overwhelming force concentration that may consist of armored and motorized or mechanized infantry formations; together with artillery, air assault, and close air support; with intent to break through the opponent's lines of defense, dislocate the defenders, unbalance the enemies by making it difficult to respond to the continuously changing front, and defeat them in a decisive Vernichtungsschlacht: a battle of annihilation.
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 and the Nazi–Soviet Pact.
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.
World War II or the Second World War was a global conflict that lasted from 1939 to 1945. The vast majority of the world's countries, including all the great powers, fought as part of two opposing military alliances: the Allies and the Axis. Many participating countries invested all available economic, industrial, and scientific capabilities into this total war, blurring the distinction between civilian and military resources. Aircraft played a major role, enabling the strategic bombing of population centres and delivery of the only two nuclear weapons ever used in war. It was by far the deadliest conflict in history, resulting in 70–85 million fatalities. Millions died due to genocides, including the Holocaust, as well as starvation, massacres, and disease. In the wake of Axis defeat, Germany, Austria, and Japan were occupied, and war crime tribunals were conducted against German and Japanese leaders.
Heinz Wilhelm Guderian was a German general during World War II who, after the war, became a successful memoirist. An early pioneer and advocate of the "blitzkrieg" approach, he played a central role in the development of the panzer division concept. In 1936, he became the Inspector of Motorized Troops.
Richard James Overy is a British historian who has published on the history of World War II and Nazi Germany. In 2007, as The Times editor of Complete History of the World, he chose the 50 key dates of world history.
The Eastern Front was a theatre of World War II fought between the European Axis powers and Allies, including the Soviet Union (USSR) and Poland. It encompassed Central Europe, Eastern Europe, Northeast Europe (Baltics), and Southeast Europe (Balkans), and lasted from 22 June 1941 to 9 May 1945. Of the estimated 70–85 million deaths attributed to World War II, around 30 million occurred on the Eastern Front, including 9 million children. The Eastern Front was decisive in determining the outcome in the European theatre of operations in World War II, eventually serving as the main reason for the defeat of Nazi Germany and the Axis nations. It is noted by historian Geoffrey Roberts that "More than 80 per cent of all combat during the Second World War took place on the Eastern Front".
Western betrayal is the view that the United Kingdom, France, and sometimes the United States failed to meet their legal, diplomatic, military, and moral obligations with respect to the Czechoslovak and Polish states during the prelude to and aftermath of World War II. It also sometimes refers to the treatment of other Central and Eastern European states at the time.
Icebreaker: Who Started the Second World War? is a military history book by the Russian non-fiction author Viktor Suvorov, published in 1988. Suvorov argued that Joseph Stalin planned a conquest of Europe for many years, and was preparing to launch a surprise attack on Nazi Germany at the end of summer of 1941 to begin that plan. He says that Operation Barbarossa was a pre-emptive strike by Adolf Hitler, a claim which the Nazi leader himself had made at the time. Since the 1990s and the dissolution of the Soviet Union, this theory has received some support among historians in some post-Soviet and Central European states, but Western scholars have criticized his conclusions for lack of evidence and documentation.
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.
Andreas Fritz Hillgruber was a conservative German historian who was influential as a military and diplomatic historian who played a leading role in the Historikerstreit of the 1980s. In his controversial book Zweierlei Untergang, he wrote that historians should "identify" with the Wehrmacht fighting on the Eastern Front and asserted that there was no moral difference between Allied policies towards Germany in 1944 and 1945 and the genocide waged against the Jews. The British historian Richard J. Evans wrote that Hillgruber was a great historian whose once-sterling reputation was in ruins as a result of the Historikerstreit.
The historiography of World War II is the study of how historians portray the causes, conduct, and outcomes of World War II.
The State Defense Committee was an extraordinary organ of state power in the Soviet Union during the German-Soviet War, also called the Great Patriotic War, with complete state power in the country.
Sir Basil Henry Liddell Hart, commonly known throughout most of his career as Captain B. H. Liddell Hart, was a British soldier, military historian, and military theorist. He wrote a series of military histories that proved influential among strategists. Arguing that frontal assault was bound to fail at great cost in lives, as proven in World War I, he recommended the "indirect approach" and reliance on fast-moving armoured formations.
The Wehrmacht were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the Heer (army), the Kriegsmarine (navy) and the Luftwaffe. The designation "Wehrmacht" replaced the previously used term Reichswehr and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted.
After the Munich Agreement, the Soviet Union pursued a rapprochement with Nazi Germany. On 23 August 1939 the Soviet Union signed a non-aggression pact with Germany which included a secret protocol that divided Eastern Europe into German and Soviet "spheres of influence", anticipating potential "territorial and political rearrangements" of these countries. Germany invaded Poland on 1 September 1939, starting World War II. The Soviets invaded eastern Poland on 17 September. Following the Winter War with Finland, the Soviets were ceded territories by Finland. This was followed by annexations of the Baltic states and parts of Romania.
Geoffrey Roberts is a British historian of World War II working at University College Cork. He specializes in Soviet diplomatic and military history of World War II. He was professor of modern history at University College Cork (UCC) in Ireland and head of the School of History at UCC.
The Soviet offensive plans controversy was a debate among historians in the late 20th and early 21st centuries as to whether Joseph Stalin had planned to launch an attack against Nazi Germany in the summer of 1941. The controversy started with Viktor Suvorov with his 1988 book Icebreaker:Who started the Second World War? where he argued, based on his analysis of historical documents and data, that Stalin used Nazi Germany as a proxy to attack Europe.
