Causes Of WW2 Flashcards
Impact of the Treaty of Versailles on Weimar Germany
During the interwar period, deep anger arose in the Weimar Republic over the conditions of the 1919 Treaty of Versailles, which punished Germany for its role in World War I with heavy financial reparations and severe limitations on its military that were intended to prevent it from becoming a military power again. The demilitarisation of the Rhineland, the prohibition of German unification with Austria, and the loss of its overseas colonies as well as some 12% of its pre-war land area and population all provoked strong currents of revanchism in German politics.
Immediate Causes of WW2
The causes of World War II have been given considerable attention by historians. The immediate precipitating event was the invasion of Poland by Nazi Germany on September 1, 1939, and the subsequent declarations of war on Germany made by Britain and France, but many other prior events have been suggested as ultimate causes. Primary themes in historical analysis of the war’s origins include the political takeover of Germany in 1933 by Adolf Hitler and the Nazi Party; Japanese militarism against China, which led to the Japanese invasion of Manchuria and the Second Sino-Japanese War; Italian aggression against Ethiopia, which led to the Second Italo-Ethiopian War; or military uprising in Spain, which led to the Spanish Civil War.
Rise of Totalitarian Regimes and Pathways to War
During the worldwide economic crisis of the Great Depression in the 1930s, many people lost faith in liberal democracy and countries across the world turned to authoritarian regimes.[1] In Germany, resentment over the terms of the Treaty of Versailles was intensified by the instability of the German political system, as many on both the Right and the Left rejected the Weimar Republic liberalism. The most extreme political aspirant to emerge from that situation was Adolf Hitler, the leader of the Nazi Party. The Nazis took totalitarian power in Germany from 1933 and demanded the undoing of the Versailles provisions. Their ambitious and aggressive domestic and foreign policies reflected their ideologies of antisemitism, unification of all Germans, the acquisition of “living space” (Lebensraum) for agrarian settlers, the elimination of Bolshevism and the hegemony of an “Aryan”/”Nordic” master race over “subhumans” (Untermenschen) such as Jews and Slavs. Other factors leading to the war included the aggression by Fascist Italy against Ethiopia, militarism in Imperial Japan against China, and Nationalists fighting against Republicans for control of Spain.
Failure of Appeasement and Escalation Toward War
At first, the aggressive moves met with only feeble and ineffectual policies of appeasement from the other major world powers. The League of Nations proved helpless, especially regarding China and Ethiopia. A decisive proximate event was the 1938 Munich Conference, which formally approved Germany’s annexation of the Sudetenland from Czechoslovakia. Hitler promised it was his last territorial claim, nevertheless in early 1939, he became even more aggressive, and European governments finally realised that appeasement would not guarantee peace but by then it was too late.
Formation of the Axis Powers and the Molotov–Ribbentrop Pact
Britain and France rejected diplomatic efforts to form a military alliance with the Soviet Union, and Hitler instead offered Stalin a better deal in the Molotov–Ribbentrop Pact of August 1939. An alliance formed by Germany, Italy, and Japan led to the establishment of the Axis powers.
Post-War Europe and the Treaty of Versailles: French Security and Revenge
By the end of World War I in late 1918, the world’s social and geopolitical circumstances had fundamentally and irrevocably changed. The Allies had been victorious, but many of Europe’s economies and infrastructures had been devastated, including those of the victors. France, along with the other victors, was in a desperate situation regarding its economy, security and morale and understood that its position in 1918 was “artificial and transitory”.[2] Thus, French Prime Minister Georges Clemenceau worked to gain French security via the Treaty of Versailles, and French security demands, such as reparations, coal payments, and a demilitarised Rhineland, took precedence at the Paris Peace Conference of 1919–1920,[2] which designed the treaty. The war “must be someone’s fault – and that’s a very natural human reaction”, analysed the historian Margaret MacMillan.[3] Germany was charged with the sole responsibility of starting World War I, and the War Guilt Clause was the first step to satisfying revenge for the victor countries, especially France, against Germany. Roy H. Ginsberg argued, “France was greatly weakened and, in its weakness and fear of a resurgent Germany, sought to isolate and punish Germany… French revenge would come back to haunt France during the Nazi invasion and occupation twenty years later”.[4]
French Security Provisions: Reparations, Coal, and Demilitarisation
The two main provisions of the French security agenda were war reparations from Germany in the form of money and coal and a detached German Rhineland. The German (Weimar Republic) government printed excess currency, which created inflation, to compensate for the lack of funds, and it borrowed money from the United States. Reparations from Germany were needed to stabilise the French economy.[5] France also demanded for Germany to give France its coal supply from the Ruhr to compensate for the destruction of French coal mines during the war. The French demanded an amount of coal that was a “technical impossibility” for the Germans to pay.[6] France also insisted on the demilitarisation of the German Rhineland in the hope of hindering any possibility of a future German attack and giving France a physical security barrier between itself and Germany.[7] The inordinate amount of reparations, coal payments and the principle of a demilitarised Rhineland were largely viewed by the Germans as insulting and unreasonable.
Criticisms of the Treaty of Versailles: Ineffectiveness and German Resentment
The resulting Treaty of Versailles brought a formal end to the war but was judged by governments on all sides of the conflict. It was neither lenient enough to appease Germany nor harsh enough to prevent it from becoming a dominant continental power again.[8] The German people largely viewed the treaty as placing the blame, or “war guilt”, on Germany and Austria-Hungary and as punishing them for their “responsibility”, rather than working out an agreement that would assure long-term peace. The treaty imposed harsh monetary reparations and requirements for demilitarisation and territorial dismemberment, caused mass ethnic resettlement and separated millions of ethnic Germans into neighbouring countries.
Hyperinflation and Political Instability in Weimar Germany
In the effort to pay war reparations to Britain and France, the Weimar Republic printed trillions of marks, which caused hyperinflation. Robert O. Paxton stated, “No postwar German government believed it could accept such a burden on future generations and survive…”.[5] Paying reparations to the victorious side had been a traditional punishment with a long history of use, but it was the “extreme immoderation” that caused German resentment. Germany did not make its last World War I reparation payment until 3 October 2010,[9] 92 years after the end of the war. Germany also fell behind its coal payments because of a passive resistance movement against France.[10] In response, the French invaded the Ruhr and occupied it. By then, most Germans had become enraged with the French and placed the blame for their humiliation on the Weimar Republic. Adolf Hitler, a leader of the Nazi Party, attempted a coup d’état in 1923 in what became known as the Beer Hall Putsch, and he intended to establish a Greater Germanic Reich.[11] Although he failed, Hitler gained recognition as a national hero by the German population.
Post-War Territorial Changes and the Dolchstosslegende
During the war, German colonies outside Europe had been annexed by the Allies, and Italy took the southern half of Tyrol after the armistice. The war in the east had ended with the defeat and the collapse of the Russian Empire, and German troops had occupied large parts of Eastern and Central Europe with varying degrees of control and established various client states such as a kingdom of Poland and the United Baltic Duchy. The German Navy spent most of the war in port, only to be turned over to the Allies. It was scuttled by its own officers to avoid it from being surrendered. The lack of an obvious military defeat would become one of the pillars holding together the Dolchstosslegende (“stab-in-the-back myth”), which gave the Nazis another propaganda tool.
Demilitarisation and Military Restrictions: German Resentment and Rising Extremism
The demilitarised Rhineland and the additional cutbacks on military also infuriated the Germans. Although France logically wanted the Rhineland to be a neutral zone, France had the power to make their desire happen, which merely exacerbated German resentment of the French. In addition, the Treaty of Versailles dissolved the German general staff, and possession of navy ships, aircraft, poison gas, tanks and heavy artillery was also made illegal.[7] The humiliation of being bossed around by the victor countries, especially France, and being stripped of their prized military made the Germans resent the Weimar Republic and idolise anyone who stood up to it.[12] Austria also found the treaty unjust, which encouraged Hitler’s popularity.
Broken Promises and Global Resentment: The Aftermath of the Treaty of Versailles
The conditions generated bitter resentment towards the war’s victors, who had promised the Germans that US President Woodrow Wilson’s Fourteen Points would be a guideline for peace; but the Americans had played only a minor role in the war, and Wilson could not convince the Allies to agree to adopt his Fourteen Points. Many Germans felt that the German government had agreed to an armistice based on that understanding, and others felt that the German Revolution of 1918–1919 had been orchestrated by the “November criminals”, who later assumed office in the new Weimar Republic. The Japanese also started to express resentment against Western Europe for how they were treated during the negotiations of the Treaty of Versailles. The Japanese proposition to discuss the issue of racial equality was not put in the final draft because of many other Allies, and the Japanese participation in the war caused little reward for the country.[13] The war’s economic and psychological legacies persisted well into the Interwar period.
Failure of the League of Nations
The League of Nations was an international peacekeeping organization founded in 1919 with the explicit goal of preventing future wars.[14] The League’s methods included disarmament, collective security, the settlement of disputes between countries by negotiations and diplomacy and the improvement of global welfare. The diplomatic philosophy behind the League represented a fundamental shift in thought from the preceding century. The old philosophy of “concert of nations”, which grew out of the Congress of Vienna (1815), saw Europe as a shifting map of alliances among nation-states, which created a balance of power that was maintained by strong armies and secret agreements. Under the new philosophy, the League would act as a government of governments, with the role of settling disputes between individual nations in an open and legalist forum. Despite Wilson’s advocacy, the United States never joined the League of Nations.
The League lacked an armed force of its own and so depended on member nations to enforce its resolutions, uphold economic sanctions that the League ordered or provide an army when needed for the League to use. However, individual governments were often very reluctant to do so. After numerous notable successes and some early failures in the 1920s, the League ultimately proved incapable of preventing aggression by the Axis Powers in the 1930s. The reliance upon unanimous decisions, the lack of an independent body of armed forces and the continued self-interest of its leading members meant that the failure was arguably inevitable.
Expansionism and Militarism: Re-emergence of Aggressive Policies in the Interwar Period
Expansionism is the doctrine of expanding the territorial base or economic influence of a country, usually by means of military aggression. Militarism is the principle or policy of maintaining a strong military capability to use aggressively to expand national interests and/or values, with the view that military efficiency is the supreme ideal of a state.[17]
The Treaty of Versailles and the League of Nations had sought to stifle expansionist and militarist policies by all actors, but the conditions imposed by their creators imposed on the world’s new geopolitical situation and the technological circumstances of the era only emboldened the re-emergence of those ideologies during the Interwar Period. By the early 1930s, militaristic and aggressive national ideologies prevailed in Germany, Japan and Italy.[18] The attitude fuelled advancements in military technology, subversive propaganda and ultimately territorial expansion. It has been observed that the leaders of countries that have been suddenly militarised often feel a need to prove that their armies are formidable, which was often a contributing factor in the start of conflicts such as the Second Italo-Ethiopian War and the Second Sino-Japanese War.[19]
Expansionist Ambitions: Italian Fascism and Nazi Germany’s Territorial Goals
In Italy, Benito Mussolini sought to create a New Roman Empire, based around the Mediterranean. Italy invaded Ethiopia as early as 1935, Albania in early 1938, and later Greece. The invasion of Ethiopia provoked angry words and a failed oil embargo from the League of Nations. Spazio vitale (“living space”) was the territorial expansionist concept of Italian Fascism. It was analogous to Nazi Germany’s concept of Lebensraum and the United States’ concept of “Manifest Destiny”. Fascist ideologist Giuseppe Bottai likened this historic mission to the deeds of the ancient Romans.[20]
Under the Nazi regime, Germany began its own program of expansion that sought to restore its “rightful” boundaries. As a prelude toward its goals, the Rhineland was remilitarised in March 1936.[21] Also of importance was the idea of a Greater Germany, supporters of which hoped to unite the German people under one nation-state to include all territories inhabited by Germans, even if they happened to be a minority in a particular territory. After the Treaty of Versailles, a unification between Germany and the newly formed German-Austria, a rump state of Austria-Hungary, was blocked by the Allies, despite the large majority of Austrians supporting the idea.
Militarism and the Rise of the Nazi Party: From the Kapp Putsch to Irredentist Ambitions
During the Weimar Republic (1919–1933), the Kapp Putsch, an attempted coup d’état against the republican government, was launched by disaffected members of the armed forces. Later, some of the more radical militarists and nationalists were submerged in grief and despair into the Nazi Party, and more moderate elements of militarism declined. The result was an influx of militarily-inclined men into the Nazi Party. Combined with its racial theories, that fuelled irredentist sentiments and put Germany on a collision course for war with its immediate neighbours.
Japanese Expansionism and Military Influence: From the Mukden Incident to the February 26 Incident
In Asia, the Empire of Japan harboured expansionist desires towards Manchuria and the Republic of China. Two contemporaneous factors in Japan contributed both to the growing power of its military and the chaos in its ranks before World War I. One was the Cabinet Law, which required the Imperial Japanese Army (IJA) and the Imperial Japanese Navy (IJN) to nominate cabinet members before changes could be formed. That essentially gave the military a veto power over the formation of any Cabinet in the ostensibly-parliamentary country. The other factor was gekokujō, the institutionalized disobedience by junior officers. It was common for radical junior officers to press their goals to the extent of assassinating their seniors. In 1936, the phenomenon resulted in the February 26 Incident in which junior officers attempted a coup d’état and killed leading members of the Japanese government. In the 1930s, the Great Depression wrecked Japan’s economy and gave radical elements within the Japanese military the chance to force the entire military into working towards the conquest of all of Asia.
For example, in 1931, the Kwantung Army, a Japanese military force stationed in Manchuria, staged the Mukden Incident, which sparked the invasion of Manchuria and its transformation into the Japanese puppet state of Manchukuo.
Germans vs. Slavs
Twentieth-century events marked the culmination of a millennium-long process of intermingling between Germans and Slavic people. The rise of nationalism in the 19th century made race a centerpiece of political loyalty. The rise of the nation-state had given way to the politics of identity, including pan-Germanism and pan-Slavism. Furthermore, Social Darwinist theories framed the coexistence as a “Teuton vs. Slav” struggle for domination, land, and limited resources.[22] Integrating these ideas into their own worldview, the Nazis believed that the Germans, the “Aryan race”, were the master race and that the Russians and Poles were inferior.[23]
Japan’s Expansionist Goals and Economic Ambitions in East Asia
Other than a few coal and iron deposits and a small oil field on Sakhalin Island, Japan lacked strategic mineral resources. In the early 20th century, in the Russo-Japanese War, Japan had succeeded in pushing back the East Asian expansion of the Russian Empire in competition for Korea and Manchuria.
Japan’s goal after 1931 was economic dominance of most of East Asia, often expressed in the Pan-Asian terms of “Asia for the Asians”.[24] Japan was determined to dominate the China market, which the US and other European powers had been dominating. On October 19, 1939, US Ambassador to Japan Joseph C. Grew, in a formal address to the America-Japan Society, stated that
the new order in East Asia has appeared to include, among other things, depriving Americans of their long established rights in China, and to this the American people are opposed…. American rights and interests in China are being impaired or destroyed by the policies and actions of the Japanese authorities in China.[25]
Nazi dictatorship
Hitler and his Nazis took full control of Germany in 1933–34 (Machtergreifung), turning it into a dictatorship with a highly hostile outlook toward the Treaty of Versailles and Jews.[40] It solved its unemployment crisis by heavy military spending.[41]
Hitler’s diplomatic tactics were to make seemingly-reasonable demands and to threaten war if they were not met. After concessions were made, he accepted them and moved onto a new demand.[42] When opponents tried to appease him, he accepted the gains that were offered and went to the next target. That aggressive strategy worked as Germany pulled out of the League of Nations (1933), rejected the Versailles Treaty, began to rearm with the Anglo-German Naval Agreement (1935), won back the Saar (1935), re-militarized the Rhineland (1936), formed an alliance (“axis”) with Mussolini’s Italy (1936), sent massive military aid to Franco in the Spanish Civil War (1936–39), seized Austria (1938), took over Czechoslovakia after the British and French appeasement of the Munich Agreement of 1938, formed a peace pact with Stalin’s Russia in August 1939 and finally invaded Poland in September 1939.[43]
Japanese Expansion and Rising Tensions with the US: From the Co-Prosperity Sphere to the Oil Embargo
In 1931, Japan invaded Manchuria and China proper. Under the guise of the Greater East Asia Co-Prosperity Sphere, with slogans such as “Asia for the Asians!”, Japan sought to remove the Western powers’ influence in China and replace it with Japanese domination.[26][27]
The ongoing conflict in China led to a deepening conflict with the US in which public opinion was alarmed by events such as the Nanking Massacre and growing Japanese power. Lengthy talks were held between the US and Japan. The Japanese invasion of the south of French Indochina made President Franklin Roosevelt freeze all Japanese assets in the US. The intended consequence was to halt oil shipments from the US to Japan, which supplied 80 percent of Japanese oil imports. The Netherlands and Britain followed suit.
With oil reserves that would last only a year and a half during peacetime and much less during wartime, the ABCD line left Japan two choices: comply with the US-led demand to pull out of China or seize the oilfields in the East Indies from the Netherlands. The Japanese government deemed it unacceptable to retreat from China.[28]
Remilitarization of the Rhineland
In violation of the Treaty of Versailles and the spirit of the Locarno Pact and the Stresa Front, Germany remilitarized the Rhineland on March 7, 1936, by moving German troops into the part of western Germany in which according to the Versailles Treaty, they were not allowed. Neither France nor Britain was prepared to fight a preventive war to stop the violation and so there were no consequences.[44]
Italian invasion of Abyssinia
Following the Stresa Conference and even as a reaction to the Anglo-German Naval Agreement, the Italian dictator Benito Mussolini attempted to expand the Italian Empire in Africa by invading the Ethiopian Empire, also known as the Abyssinian Empire. The League of Nations declared Italy to be the aggressor and imposed sanctions on oil sales, which proved ineffective. Italy annexed Ethiopia in May 1936 and merged Ethiopia, Eritrea and Somaliland into a single colony, known as Italian East Africa. On June 30, 1936, Ethiopian Emperor Haile Selassie gave a stirring speech before the League of Nations denouncing Italy’s actions and criticizing the world community for standing by. He warned, “It is us today. It will be you tomorrow”. As a result of the League’s condemnation of Italy, Mussolini declared the country’s withdrawal from the organization.[45]
Spanish Civil War
Between 1936 and 1939, Germany and Italy lent support to the Nationalists led by general Francisco Franco in Spain, and the Soviet Union supported the existing democratically elected government, the Spanish Republic, led by Manuel Azaña. Both sides experimented with new weapons and tactics. The League of Nations was never involved, and its major powers remained neutral and tried with little success to stop arms shipments into Spain. The Nationalists eventually defeated the Republicans in 1939.[46]
Spain negotiated with joining the Axis but remained neutral during World War II and did business with both sides. It also sent a volunteer unit to help the Germans against the Soviets. The Spanish Civil War was considered in the 1940s and 1950s to be a prelude to World War II, which was the case to some extent by changing it into an antifascist contest after 1941, but bore no resemblance to the war that started in 1939 and had no major role in causing it.[47][48]
