Furthermore the failure of the League of Nations caused World war two due to the lack of protection given by the League to countries when aggression was shown by Germany. This absence caused the vulnerable countries and their allies to be aggressive, again provoking war. The Abyssinia crisis and Manchuria gave Hitler the opportunities he needed to march into the demilitarised Rhineland and re-arm Germany ready for conflict. Also soon the idea of collective security was all but dead leading to great powers to return to traditional diplomacy and forming new alliances and agreements, for example the Munich agreement and Nazi-soviet pact. The league was weak and allowed dictators like Hitler to do whatever they pleased, for example invade Poland. If the league had still been powerful and able to protect Poland then Germany possibly wouldn’t have invaded and so doing this provoked Britain and France to declare war, therefore starting war. Therefore the war which started September 1939 was due to the failure of the league as there was not a strong enough power to protect Poland stop Hitler.
Equally Hitler’s policy of appeasement was a reason why World War 2 started. The appeasement gave hitler confidence to be more forward and aggressive with his aims to achieve a “grossen deutschen land” and completely wipe out communism. In fact Britain and France were entirely responsible for giving Hitler confidence as they keep on giving into his demands. They put too much trust in Hitler’s promises and assumed that he had the same vision and western desire for peace, however they failed to recognise Hitler’s unlying goal and inherited ideology that sought war. Britain and France was weak and inferior which was obvious to Hitler, this encouraged Hitler to achieve appeasement. As Germany became stronger and stronger they developed military strength, more lebensraum (living space) and gained resources, like industry perfect for preparing for the inevitable war that Hitler was intent would happen. The policy of appeasement also caused the union between Russia and Germany called the Nazi-soviet pact this was due to Hitler’s plan to invade Poland, therefore making it eventually easier to invade Russia, gain more lebensraum and power. Originally Russia and Germany were enemies, and although Starlin knew that Hitler was planning to invade and cause war, he had lost all trust and reliance in Britain and France and thought that making the pact would give Russia more time. This pact allowed Germany to invade Poland thus creating war, as Hitler had disobeyed Britain and France. Therefore Hitler’s confident in his policy of appeasement was an equal reason for the cause of WW2.
In conclusion all three of these reasons are connected to one another there by making them all equal reasons why WW2 happened. With-out one of them the war probably wouldn’t have happened as they all lead to when the Germans invaded Poland. Firstly if Hitler hadn’t had been so aggressive, he most likely wouldn’t have invaded Poland and Britain wouldn’t have declared war. Secondly the failures of the league lead to there being no protector for Poland, thus making the invasion easy for Hitler, therefore causing war. And thirdly if appeasement hadn’t of been so successful Hitler wouldn’t of been as confident, leading him to make the Nazi-soviet pact which gave him power and strength to invade Poland, which evidently was the penultimate cause for WW2. Therefore all three reasons were equally important to why there was a WW2 in 1939.
