The sine qua non of the Second World War, without which it never would have occurred, was The Great Depression, which started in 1929, one of the most significant causes of the WWII. During the First World War, whilst the countries that were fighting had to slow down their production, the young nations developed their own lands to supply the combatants in return for the price of gold. Take as an example the American giant. From 1913 to 1919 the annual production of corn rose in the United States from seven hundred and sixty-three to nine hundred and fifty-two million bushels; that of steel, from twenty-six to forty-two million tons.
After the war Europe rebuilt herself. In ten years she regained her productive capacity of 1913. Failing to appreciate this essential fact, the young countries indulged in the debauchery of stupendous credit transactions. In 1933, the American farmers piled up debts of more than eight milliard dollars in order to improve their machinery and raise their output. Nor was it sufficient to grant huge credits only to producers. These credits were also offered to consumers. Here is one example: the motor industry, the most important in the United States, sold on credit seventy per cent of its output. The crisis was of unparalleled violence in Germany. From six hundred and fifty thousand in August, 1928, the number of workless rose to two million and three hundred thousand in 1929, to three million five hundred thousand in 1930, and to six million by the end of 1932. The depression devastated the world economy. It was the worst economic downturn in modern times. As a cause of WWII, it was instrumental. As Alan Bullock has famously stated: "It was the depression which tipped the scales against the [Weimar] Republic and for the first time since 1923, shifted the weight of advantage to Hitler's side." The depression provided Hitler, who was more than any other factor responsible for the outbreak of WWII, with a chance to take power in Germany and put into practice his Nazi ideology and influence the disillusioned people of his country. "Germany was a special case. The Germans had experienced the terrible evils of inflation in 1923, and now went equally far in the opposite direction. (AJP Taylor)" Germans looked towards the two extremes (Communism and National Socialism) to provide a solution to this horrible depression. AJP Taylor claims that "The depression put the wind into Hitler's sails." The Great Depression was a major background cause to WWII - since it gave rise to Adolf Hitler, who was to a great extent responsible for the outbreak of WWII in 1939.
In The World in Depression, Kindleberger explained the need for the international economic and monetary system, during difficult periods, to have a world power to underwrite the world community, maintain a proper flow of investment capital, and take on bad debts. Britain had often performed this role through 1913; the particular virulence of the Great Depression stemmed partly from the lack of leadership of one dominant national state. In 1929, 1930, and 1931 Britain could not act as a stabilizer, and the United States would not. When every country turned to protect its national private interest, the world public interest went down the drain, and with it the private interests of all. The lack of leadership among the liberal states of the West fed the political extremism of regimes that eventually provoked war.
One of the finest works on European economic diplomacy in the decade leading to the outbreak of war is Kaiser, Economic Diplomacy and the Origins of the Second World War. Kaiser discussed at length the great European powers and their rivalry in the economic expansion of Central and Eastern Europe. As early as 1914 he detailed the German plan for dominance of Central Europe Mitteleuropa. With the Russian collapse of 1917-1918, it seemed as if the dream would come to fruition as Germany seized Romania and Ukraine. However, as Kaiser noted, the sudden collapse of the German armies in late 1918 led this desideratum to be foiled with the Allied and associated victory. It was revived some twenty years later with the relentless Nazi quest for Lebensraum. Kaiser concluded that because the Western pperowers failed to defend the status quo in Eastern Europe, many of the weaker nations were forced into economic dependence on Nazi Germany, especially after the betrayal of the Czechs by their British and French allies at Munich. He reasoned that the democracies would pay heavily for these mistakes in judgment, and that they did, in a ruinous six-year war. (Ruth Norden, 33-38)
The economic orientation of the Third Reich is compelling as a rationale for a military offensive, as in the German strike against Norway in April 1940 because British efforts to mine Scandinavian ports would have resulted in disruption of critical exports of Swedish iron ore to Germany. Later in Poland to Pearl Harbor that because of economic considerations, the real "point of no return . . . after which the Third Reich was irretrievably committed to war . . . occurred in the 18 months between the summer of 1936 and the spring of 1938. (R. J.B. Bosworth, 8-19)" The fact that Germany's rivals had begun rearmament, however halting, made the Nazi preparations for war a self-fulfilling prophecy in the late 1930s.
Another cause of the Second World War was the personality of Hitler. Some day, Hitler recognized, Britain and France would be tempted to set limits to German power, even by war. In preparation for that day, he argued, Germany must not only strain her resources in military preparations; she must also win territory sufficient to feed her people during a long war - for war with the Western democracies would be both long and hard. Colonies would be of no value; their resources would be lost by blockade just when they were needed. The territory must be won in Eastern Europe. There, German skill could increase agricultural production, and the non-German population would provide a labor pool for farm and factory. Isolationist sentiment spread and overrode all internationalist tendencies. This fact had disastrous effects in Germany. Hitler became convinced that American isolationism would hold out against all provocation, and that whatever might happen in Europe, Uncle Sam would look the other way. This miscalculation of American feeling was to become one—and not the least effective—of the causes of World War Two.
Largely unfulfilled revisionism, laying the foundation for the rise of National Socialism, became one of the main causes of the Second World War. The denial of any responsibility for having started the war provided many Germans with a moral legitimization for revisionism. Others were willing to accept some blame, but only if the other nations involved would admit their own share of responsibility. However, this view was challenged by the popular historian, AJP Taylor in 1961. Taylor countered the 'traditional' argument saying that Hitler did not plan a war, he simply day-dreamed of one and let things fall into his lap so to speak by playing a waiting game. "Hitler did not make plans for world conquest or anything else. He assumed that others would provide opportunities and that he would seize them. The war of 1939, far from being premeditated was a mistake, the result of both sides of diplomatic blunders.( AJP Taylor)" As far as Taylor was concerned, Mein Kampf was written too long before Hitler came to power and can therefore not be used as evidence to prove that Hitler planned a war. Taylor argues that the Hossbach memorandum simply represents Hitler day-dreaming about things he didn't think were actually possible to achieve in reality. This is the so-called 'revisionist' view.
After the end of World War I, many democratic countries worked hard to keep peace with other countries and tried to prevent another world war. Many establishments were made to resolve all disputes between countries, although most of them failed and did not prevent the second world war.
After World War I, the United States kept out of European conflicts and war. Laws that were passed to keep the United States out of World War II were called the Neutrality Acts. Britain and France could buy weapons from the United States, but they had to pay in cash because some countries already owed the United States money. Also, American merchant ships were not allowed to carry cargo to other countrie's ports. World War I left Great Britain with a weak economy, so it was sympathetic to Germany's recovery and did not interfere. When Germany took over Rhineland (the area of land between France and Germany) and sent troops there, Great Britain did not do anything about it even thought Germany was violating the Treaty of Versailles. In 1937, Germany signed an appeasement with Great Britain saying that if Germany got Sudenteland, than it would not take over the rest of Czechoslovakia, so Great Britain did not think Germany would take over any more countries. France's economy was also hurt by World War I, so it was not strong enough to go against Germany by itself. France was unlikely to intervene against Germany because it could not rely on Great Britain or the United State's support. France could not stop the German army from coming into France because Belgium would not let them send troops into their country. If the United States and Great Britain had helped France, Germany could have been stopped before 1939.
The League of Nations was established after World War I, by Woodrow Wilson to prevent future wars. Most of the great powers joined it, except for the United States. It was made to settle disputes between countries and to try to stop other countries from taking over countries in the League of Nations. The league's powers were limited to persuasion and usually nothing was done to stop conflict between countries.
The Munich Agreement was established in 1937 to prevent war and to stop Germany from taking over other countries. It was signed by Chamberlain from Great Britain and Hitler from Germany. The agreement said that Germany could have Sudenteland if it did not invade the rest of Czechoslovakia or any other countries. In March of 1939, the Munich Agreement failed, and Germany took over the rest of Czechosolvakia, and later on other countries.
Another less heard about unsolved problem of WWI is what the historian Paul Kennedy calls 'Frontsoldaten Mentality'. At the end of the war, most people came home from where they were fighting with a pacifist mentality - that is never wanting to experience the horrors of war again. However, there were those people who thought of war as being a good experience and a positive demonstration of the force that humans were capable of unleashing. Two of the most famous of these men were Adolf Hitler and Benito Mussolini. These men came out of WWI with a frontsoldaten (frontline soldier) mentality. Out of this sprung the ideology of fascism to be later implemented in Mussolini's Italy and Hitler's Germany. David Thomson illuminates our understanding on this: "In 1919, it was assumed that all European states would in future be democratic in structure, and therefore sufficiently like-minded and peace-loving to make the machinery of the League of Nations work effectively... Among the chief reasons for its failure was the fact that an increasing number of states ceased to be democratic in structure or peace-loving in purpose." People who came out of WWI with a 'frontsoldaten mentality' rejected the ideas of internationalism and democracy. This was an unsolved problem of WWI which was to have dire consequences for the future. (Gordon Martel, 65, 89)
Conclusion:
The simpliest answer for our question: the main caiuse of the second world war is Adolf Hitler. His desire for power as a meglomaniac is duly noted by many. That is too simplistic since his desire meant nothing. He needed an impetus by which to get others to act on his personal desires. Even Nazism and anti-semitism were just tools used by those who sought power and glory. The true cause of world war two was the "Treaty of Versailles". The economic depression the treaty caused alone created animosity among germans. The treaty spurred the depression in germany and created resentment through the reparations included and the many clauses that limited germany in many ways militarily. Hitle r urged the german people on and brought a sense of national pride. Indeed, there was much territory germans felt was rightfully theirs and they took some back peacefully. This was allowed through French and British appeasement. Appeasement was a minor cause of the war. The policy probably just delayed the inevitable but it is a good lesson to learn for the modern world with regard to terrorists. World War One and World War Two have their roots in numerous issues dating back 100+ years. Ultimately the second war resulted from a bad treaty that ended the first.
