causes of world war 2 essay pdf

The Causes of WWII

The origins of the Second World War (1939-45) may be traced back to the harsh peace settlement of the First World War (1914-18) and the economic crisis of the 1930s, while more immediate causes were the aggressive invasions of their neighbours by Germany, Italy , and Japan . A weak and divided Europe , an isolationist USA, and an opportunistic USSR were all intent on peace, but the policy of appeasement only delivered what everyone most feared: another long and terrible world war.

The main causes of WWII were:

• The harsh Treaty of Versailles
• The economic crisis of the 1930s
• The rise of fascism
• Germany's rearmament
• The cult of Adolf Hitler
• The policy of appeasement by Western powers
• Treaties of mutual interest between Axis Powers
• Lack of treaties between the Allies
• The territorial expansion of Germany, Italy, and Japan
• The Nazi-Soviet Pact
• The invasion of Poland in September 1939
• The Japanese attack on the US naval base at Pearl Harbour

Treaty of Versailles

Germany was defeated in the First World War, and the victors established harsh terms to ensure that some of the costs of the war were recuperated and to prevent Germany from becoming a future threat. With European economies and populations greatly damaged by the war, the victors were in no mood to be lenient since Germany had almost won and its industry was still intact. Germany remained a dangerous state. However, Britain and France did not want a totally punitive settlement, as this might lead to lasting resentment and make Germany unable to become a valuable market for exports.

The peace terms were set out in the Treaty of Versailles, signed by all parties except the USSR on 28 June 1919. The Rhineland must be demilitarised to act as a buffer zone between Germany and France. All colonies and the Saar, a coal-rich area of western Germany, were removed from German authority. Poland was given the industrial area of Upper Silesia and a corridor to the sea, which included Danzig (Gdánsk) and cut off East Prussia from the rest of Germany. France regained the regions of Alsace and Lorraine. Germany had to pay war reparations to France and Belgium. Germany had limits on its armed forces and could not build tanks, aircraft, submarines, or battleships. Finally, Germany was to accept complete responsibility, that is the guilt, for starting the war. Many Germans viewed the peace terms as highly dishonourable.

The settlement established nine new countries in Eastern Europe, a recipe for instability since all of them disputed their borders, and many contained large minority groups who claimed to be part of another country. Germany, Italy, and Russia, once powerful again after the heavy costs of WWI, looked upon these fledgling states with imperialist envy.

In the 1920s, Germany signed two important treaties. The Locarno Treaty of 1925 guaranteed Germany's western borders but allowed some scope for change in the east. The 1928 Kellogg-Briand Pact was signed by 56 countries. All the major powers promised not to conduct foreign policy using military means. In 1929, Germany's reparations as stipulated by the Treaty of Versailles were reduced from £6.6 million to £2 million. In 1932, the reparations were cancelled altogether. This was all very promising, but through the 1930s, the complex web of European diplomacy began to quickly unravel in a climate of economic decline.

Economic Crisis

The Great Depression, sparked off by the Wall Street stock-market crash of 1929, resulted in a crisis in many economies through the 1930s. There was a collapse in world trade , prices, and employment. In Germany in 1923, there was hyperinflation, which made savings worthless, a blow many of the German middle class never forgot. The regular loans from the United States (the Dawes Plan), upon which the German economy depended, stopped. There was a hostile attitude amongst many states as international trade collapsed. The USA, the world's most important money lender, pursued an isolationist strategy. Britain and France looked only to their empires. Protectionism and trade tariffs became the norm.

Germany became determined to reach self-sufficiency and not rely on world trade partners, a policy that required the acquisition of natural resources through military occupation. Germany saw the route out of the financial mess as one of massive rearmament which would create jobs in factories and the armed forces. The policy involved not only stockpiling weapons but also creating an economy geared towards total war, where the armaments industry was given priority in terms of resources, energy, factories, and skilled workers.

Hitler & the Nazi Party

Nationalist fascist parties were doing well across Europe. From 1922, Italy was ruled by Benito Mussolini (l. 1883-1945), leader of the fascist party there. By 1939, Spain had a fascist ruler in General Franco (l. 1892-1975). In Germany, Adolf Hitler (l. 1889-1945) was the leader of the fascist National Socialist Party (Nazi Party), the largest party after the July and November elections of 1932. There were even fascist parties in democracies like Britain. Charismatic leaders were turning popular nationalist feelings into a much more sinister way of thinking: fascism. Fascist parties, although not exactly the same in different countries, did have some key goals in common. Fascist leaders wanted absolute power and to achieve this new order they emphasised "conformism, hostility to outsiders, routine violence, contempt for the weak, and extreme hatred of dissident opinions" (Dear, 274). Fascist parties initially gained popularity as opponents to communism, seen as a threat by many ever since the Russian Revolution of 1917. Indeed, in Western countries, a deep suspicion of communism prevented a powerful political and military alliance from being formed with the USSR, which might ultimately have avoided war.

Hitler promised the humiliation of Versailles would be revenged and that Germany would be made great again. Many Germans believed they had been betrayed by the high command of the army in WWI and were tired of the endless round of ineffective coalition governments since the war. Hitler, with no connections to the established elite, offered a new beginning, and most of all, he promised jobs and bread in a period when unemployment and poverty were at extremely high levels. The Nazi party promised a dynamic economy which would power German expansion, seen as a glorious endeavour, with the virtues of war championed. Nazism called for Lebensraum (living space) for the German people – new lands where they could prosper. Nazism identified its principal internal enemies as Jews, Slavs , Communists and trade unionists, all people who were holding Germany back from realising its full potential the Nazis claimed. Nazism called for an international struggle where Germans could achieve their destiny and prove themselves the master race. Such ideas, none of which were radically new, meant war was inevitable. The argument that totalitarian regimes require wars and liberal democracies require peace to prosper may be simplistic but has some validity. Hitler promised the new Third Reich would last for 1,000 years and, using propaganda, show, and brutal repression of alternative ideas, many believed him as he expertly tapped into long-held views in Germany and Austria. As F. McDonough states, "Hitler was the drummer of an old tune accompanied by modern instruments" (93).

In January 1933, the German President Paul von Hindenburg (l. 1847-1934), having run out of all other options, invited Hitler to become Chancellor. After systematically crushing any opposition, Hitler began to put his domestic policies into practice and establish a totalitarian regime, everything he had written in his book Mein Kampf ( My Struggle ) back in 1924. When Hindenburg died in August 1934, Hitler effectively merged the positions of President and Chancellor and declared himself Germany's leader or Führer. Hitler had become the state, and all that was now needed for him to achieve his impossible dream was a rearmed Germany.

Germany's Rearmament

Hitler was determined to rebuild the nation's armed forces. Rearmament rocketed despite the restrictions of Versailles, which Hitler formally repudiated in March 1935. The army was already four times bigger than permitted. Eventually, Western powers were obliged to take a damage-limitation approach. In June 1935, the Anglo-German Naval Agreement was signed, which capped the German navy's strength to 35% of the Royal Navy and allowed Hitler to build giant new ships like the battleship Bismarck .

In another instance of the cult of Adolf Hitler, all armed forces personnel had to swear allegiance to Hitler personally. Thanks to rearmament, Germany had achieved near-full employment by 1938. Hitler had fulfilled his promises to the German people. Germany's new war machine came at a cost. Rearming necessitated huge imports of raw materials, and these could not be bought for much longer as Germany's balance of payments went into tilt from 1939. Occupying territories where these resources could be found seemed a simple solution to the problem. Crucially, Germany had an arms advantage over its enemies, but this situation would not last long. For Hitler, the time to strike was now.

Appeasement

Allowing Germany to rearm was part of the policy of appeasement: giving reasonable concessions to avoid the total disaster of war. Appeasement, which was pursued by Britain, France, and the United States, did not mean peace at any price, but the problem with the policy was that it did give, step by step, aggressive powers the impression that their continued aggression might not necessarily lead to a wider war. To review these steps, we must look at global politics in the early 1930s.

The League of Nations (forerunner of today's United Nations) was established after WWI to ensure international disputes were settled and world peace was maintained. Although US President Woodrow Wilson (in office 1913-21) was instrumental in forming the League, crucially, the United States never joined it, seriously weakening the organisation. Germany joined in 1926 but left in 1933; Japan left the same year. The League proved to be utterly incapable of achieving its aims, as was shown most starkly by its failure to prevent Japan's invasion of Manchuria in September 1931 and Italy's invasion of Abyssinia (Ethiopia) in October 1935. Hitler no doubt watched these events and the League's total lack of a military response with particular interest as, with his own armed forces rejuvenated, he prepared to expand Germany's borders.

From 1933 to 1935, Hitler had pursued an ambiguous foreign policy, sometimes promising he had peaceful intentions. He caused confusion with such diplomatic conjuring tricks as a peace treaty with Poland in January 1934 and a statement later the same year that he had no intention of merging Austria into the Reich. Then, from 1935, his plans became ever clearer, even if some historians maintain the Führer actually had no plans at all but was merely seizing opportunities as his enemies presented them. Some historians claim Hitler was not entirely free to act as he would wish, due to constraints within the rather chaotic and factional Nazi party. In March 1935, the Saar was reunified with Germany following a plebiscite. The same year, conscription was announced. In March 1936, Germany occupied the Rhineland. In October, Germany and Italy became formal allies with the Rome -Berlin Axis. In November 1936, Italy and Germany (and later Japan) signed the Anti-Comintern Pact, a treaty of mutual cooperation in empire -building and a united front against communism. In March 1938, Hitler achieved the Anschluss, the formal unification of Germany and Austria. Encouraged by the League of Nations' lack of a strong response, Hitler then occupied the Sudetenland, the industrial area of Czechoslovakia which shared a border with Germany, the excuse being a German minority there was being repressed. Again, the Western powers made no military reaction despite France and the USSR having signed a treaty of assistance with the Czechs. The Munich Agreement of September 1938 was signed between Germany, France, Italy, and Britain, which accepted Germany's new, expanded borders. The USSR was not invited, a lost and last opportunity to present a united front against fascism – perhaps here was the real price of pursuing a policy of appeasement to the exclusion of any other possible strategies. The British Prime Minister Neville Chamberlain (served 1937-40), fluttering before journalists a piece of paper Hitler had signed, confidently declared that he had achieved "peace with honour" (Dear, 597) and that we now had "peace in our time" (McDonough, 121). Chamberlain was nominated for that year's Nobel Peace Prize.

Appeasement was an attractive policy to Western leaders since the horrors of the last war were still fresh in everyone's minds. France, in particular, was politically weak in this period, experiencing 16 coalition governments through the 1930s. Britain feared losing its empire if weakened by another great war. Public opinion was overwhelmingly against war and rearmament in Britain, France, and the United States. Further, it was by no means certain that Hitler would continue to expand Germany's borders; certainly, he had promised he had no additional ambitions beyond restoring Germany to its previous territories before WWI. Finally, appeasement, even if not actually believed to be a policy with any chance of success, did gain crucial time for Western powers to follow Germany's lead and rearm. In Britain and France, there were, too, strong lobbies which considered rearmament a waste of resources in economically turbulent times and pointed out that Germany was Britain's fifth largest customer for its exports. Hindsight has shown that appeasement was folly since Hitler was intent on occupying as much of Europe as he possibly could, and his track record of breaking treaties proved negotiation was pointless. Keeping the Czech heavy industry out of German hands was probably a better point to go to war over than the subsequent invasion of Poland, but Britain, France, and the USSR were simply not then equipped for war. Not until 1939 did these countries seriously begin to establish economies geared to war.

Invasion of Poland

In 1939, there was further significant activity by Germany and Italy in their quest to occupy more and more of Europe. In March 1939, Germany absorbed the rest of Czechoslovakia and Memel (part of Lithuania) into the Third Reich. Increasingly appalled by the Nazis' attacks on German Jews, Western powers now began to question if negotiating with such a regime could ever be justified on moral grounds. Appeasement was finally dead.

On 31 March, Britain and France promised to guarantee Poland's borders, and in April, this was extended to Romania. Turkey and Greece also began talks of mutual protection with Britain and France. It had finally dawned on leaders in Britain and France that the fascists were intent on territorial expansion at any cost. There was already a localised war going on, the Spanish Civil War of 1936-39, which directly involved German and Italian military hardware on the one side and Soviet aid on the other. In April, Italy occupied Albania. At the end of the same month, Hitler repudiated the Anglo-German Naval Agreement. In May 1939, Italy and Germany signed a military alliance, the ‘Pact of Steel'.

In August 1939, Germany agreed a non-aggression pact with the Soviet Union, the Molotov-Ribbentrop Pact (Nazi-Soviet Pact), named after the foreign ministers of each state. The Soviet leader Joseph Stalin (l. 1878-1953) was increasingly aware that Britain and France seemed perfectly willing to appease Hitler as long as he moved eastwards in his direction. The possibility of 'collective security' (Britain, France, and the USSR working together) was not realised because of a lack of trust between the parties. The Nazi-Soviet Pact, in contrast, allowed Stalin to grab eastern Poland and keep the USSR out of a war for a while, gaining precious time for rearmament. Perhaps, too, the possibility for Germany to wage war only in the West against Britain and France – Stalin's 'blank cheque' for Hitler – would sufficiently weaken all three so that they could no longer threaten the USSR.

Europe was a tinder box awaiting a single spark that would explode it into war. The spark came soon enough with Germany's invasion of Poland on 1 September 1939. The next day Chamberlain warned Hitler war would follow if Germany did not withdraw. Hitler ignored the ultimatum. On 3 September, Britain and France, in order to protect free and independent nations, declared war on Germany. Italy, waiting in the wings to see what might happen to its advantage, remained neutral for the time being. The world, too, awaited with bated breath to see what would happen next. The unexpected answer was nothing at all.

The 'phoney war', when the Allies and Axis powers did not directly confront each other, lasted until April 1940 when Germany invaded Norway. In May, Germany invaded the Low Countries and France. Germany proved unstoppable, and by the end of June, France had fallen. In October, Italy invaded Greece. In 1941, Germany occupied Yugoslavia. Britain was left alone to fight for its survival until Hitler invaded the USSR in June 1941 (Operation Barbarossa).

The war became a global conflict when Japan attacked the US naval fleet at Pearl Harbour, Hawaii, on 7 December 1941. Japan had already invaded Eastern China over concern at the rise in Chinese nationalism and then occupied most of South East Asia in search of imperial glory and natural resources, especially oil, whose import was restricted by a US embargo. Japan perhaps hoped events in Europe would prevent any direct reaction against them, but the United States did finally join the conflict. Peace would not be achieved until the world had suffered four more long and bitter years of war.

History of World War II 1939 -1945

Military publishing house, Volume 1. The origin of war. The first volume of the "History of the Second World War" covers the period from the end of the First World War to the autumn of 1935. Its first part is devoted to the origin of war in the system of world imperialism, showing fascism as a strike force of imperialism and militarism, and the history of the emergence of the first centers of a new world war. The second part of the volume reveals the world-historical significance of the construction of socialism in the USSR, the development of its Armed Forces, the intense struggle of the peace-loving peoples, led by the Soviet Union, against the danger of a new world war. Translated by Svitlana M. for ML Discussion Group to study for the analysis of the war in Ukraine. Unedited.

How is extreme violence created and how does it transform states and societies? This course examines the global history of war in the twentieth century. It covers wars that liberal states, totalitarian dictatorships and colonial empires fought in Europe, Asia and Africa. The focus of the seminar is thematic, discussing issues such as total war, modern war, race war, civil war, and empire and war. We will analyze similarities and differences brought about by the dynamics of violence and ideology in these different conflicts, and examine to what extent they were connected, even interacted. Equal attention will be paid to the macro and micro levels on and between which these dynamics unfolded: from the level of states and societies down to social communities and individual lives. The course concludes with an examination of the aftermath of war, asking about the role of justice and trials in social reconstruction and reconciliation processes, and the different forms and functions of war narratives and memory. As part of the course, students will visit one of the three following museums or documentations centers in Berlin, which are also important historical sites relating to the Second World War: the Topography of Terror (where the Secret State Police, the SS and the Reich Security Main Office were located), the German-Russian Museum in Karlshorst (where the unconditional surrender of the German armed forces was signed on 8 May 1945), and the last well-preserved former Nazi forced labor camp in Schöneweide. The purpose of these visits is to explore the connection between public history and academic discussions, to analyze how and through which means the history of the Second World War is presented, and how the historical sites are incorporated into the exhibitions.

World War II in World History

Nabil Al-Tikriti

This course examines the global history of World War II from its origins in the ideological and strategic conflicts of the 1930s, through its major theaters, and finishing with the immediate postwar period. To sufficiently grasp the topic, the class shall explore the: diplomatic background to the launch of hostilities; imperial goals of the respective engaged powers; military imperatives driving battle outcomes; personal experiences of affected combatants and civilians; legacies of the settlements which defined the end of hostilities; and evolving historiography of the conflict. This version of the course will include multiple focuses and perspectives, which together will encourage the class to reflect on the long-term consequences of this global conflict. To that end, we will regularly read and discuss relevant news items pertaining to today's conflicts, and how the Second World War played a role in their evolution. There is no prerequisite for this course. Readings: Readings are drawn from the following required texts, as well as from class handouts posted on Canvas.

The International System is a self-organized system that shows emergent behavior. During the timeframe (1495-1945) covered in this study, a finite-time singularity and four accompanying accelerating log-periodic cycles shaped the dynamics of the International System. Each cycle began and ended with a systemic war. During their life span, these cycles show remarkable regularities in their dynamics. The accelerated growth of the connectivity of the regulatory network of the International System, in combination with its anarchistic structure, produce and shape the war dynamics of the system. The accelerated growth of the connectivity of the International System is fed by population growth and the need for social systems to fulfill basic requirements. The finite-time singularity and accompanying log-periodic oscillations were instrumental in the periodic reorganization of the regulatory network of the International System and contributed to a long-term process of social expansion and in...

This paper takes a contrary stand from that which is presented in the question. It start by showing that the First World War was actually a world war. It dislodges the view put forward by some historians of world history which is as stressed above. The paper begins by defining certain concept like contemporary history and then settle down to mirror these events within the Marxist theoretical framework. The paper would present the immediate cause and remote causes of the war alongside the course of the war; and then justify the stand which i have taken with concrete historical facts which

World War II began in Europe on September 1, 1939, when Germany invaded Poland. Great Britain and France responded by declaring war on Germany on September 3. The war between the U.S.S.R. and Germany began on June 22, 1941, with Operation Barbarossa , the German invasion of the Soviet Union . The war in the Pacific began on December 7/8, 1941, when Japan attacked the American naval base at Pearl Harbor and other American, Dutch, and British military installations throughout Asia.

What countries fought in World War II?

The main combatants were the Axis powers (Germany, Italy, and Japan) and the Allies (France, Great Britain, the United States, the Soviet Union, and, to a lesser extent, China).

Who were the leaders during World War II?

The Allied powers were led by Winston Churchill (United Kingdom); Joseph Stalin (Soviet Union); Charles de Gaulle (France); and Franklin D. Roosevelt and Harry S. Truman (United States). The Axis powers were led by Adolf Hitler (Germany), Benito Mussolini (Italy), and Hideki Tojo (Japan).

The war in the Pacific turned against Japan during the Battle of Midway (June 3–6, 1942), an American victory that destroyed the Japanese first-line carrier force and, together with the Battle of Guadalcanal , ended Japan’s ability to prosecute an offensive war.

The tide of the war in Europe shifted with the Soviet victory at the Battle of Stalingrad (February 1943). More than one million Soviet troops and tens of thousands of civilians died in the defense of the city, but the destruction of two entire German armies marked the beginning of the end of the Third Reich .

The Allied landings at Normandy on June 6, 1944, opened a second front in Europe, and Germany’s abortive offensive at the Ardennes in the winter of 1944–45 marked the Third Reich ’s final push in the west. The Red Army advanced from the east and effectively claimed all the territory under its control for the Soviet sphere. The Allied armies converged on Berlin. Adolf Hitler committed suicide on April 30, 1945, and the war in Europe ended on May 8.

The American “island hopping” campaign had destroyed key Japanese installations throughout the Pacific while allowing bypassed islands to wither on the vine. Hundreds of thousands were killed in firebombings of Japanese cities, and the atomic bombings of Hiroshima and Nagasaki in August 1945 knocked Japan out of the war.

Estimates of the total number of people killed during World War II have ranged from 35,000,000 to 60,000,000—a significant span, because statistics about the war’s casualties are inexact. The Soviet Union and China are believed to have suffered the most total casualties, while an estimated 5,800,000 Poles died, which represents about 20 percent of Poland’s prewar population. About 4,200,000 Germans died, and about 1,972,000 Japanese died. In all, the scale of human losses during World War II was vast. A table that details estimated deaths by country is available here .

World War II , conflict that involved virtually every part of the world during the years 1939–45. The principal belligerents were the Axis powers — Germany , Italy , and Japan —and the Allies— France , Great Britain , the United States , the Soviet Union , and, to a lesser extent, China . The war was in many respects a continuation, after an uneasy 20-year hiatus , of the disputes left unsettled by World War I . The 40,000,000–50,000,000 deaths incurred in World War II make it the bloodiest conflict, as well as the largest war, in history.

Along with World War I, World War II was one of the great watersheds of 20th-century geopolitical history. It resulted in the extension of the Soviet Union’s power to nations of eastern Europe , enabled a communist movement to eventually achieve power in China, and marked the decisive shift of power in the world away from the states of western Europe and toward the United States and the Soviet Union.

Axis initiative and Allied reaction

By the early part of 1939 the German dictator Adolf Hitler had become determined to invade and occupy Poland . Poland, for its part, had guarantees of French and British military support should it be attacked by Germany. Hitler intended to invade Poland anyway, but first he had to neutralize the possibility that the Soviet Union would resist the invasion of its western neighbour. Secret negotiations led on August 23–24 to the signing of the German-Soviet Nonaggression Pact in Moscow . In a secret protocol of this pact, the Germans and the Soviets agreed that Poland should be divided between them, with the western third of the country going to Germany and the eastern two-thirds being taken over by the U.S.S.R.

Having achieved this cynical agreement, the other provisions of which stupefied Europe even without divulgence of the secret protocol, Hitler thought that Germany could attack Poland with no danger of Soviet or British intervention and gave orders for the invasion to start on August 26. News of the signing, on August 25, of a formal treaty of mutual assistance between Great Britain and Poland (to supersede a previous though temporary agreement) caused him to postpone the start of hostilities for a few days. He was still determined, however, to ignore the diplomatic efforts of the western powers to restrain him. Finally, at 12:40 pm on August 31, 1939, Hitler ordered hostilities against Poland to start at 4:45 the next morning. The invasion began as ordered. In response, Great Britain and France declared war on Germany on September 3, at 11:00 am and at 5:00 pm , respectively. World War II had begun.
