Causes of the War
Nine Steps to War
1. The Rearmament of Germany
German rearmament began after Hitler left 1932-4 Geneva Disarmament Conference, stating that as the powers would not disarm to his level, he would rearm Germany to their level. By 1935 rearmament was well underway. This involved conscription and munitions factories.
Rearmament alarmed the French who, feeling insecure, reinforced the Maginot line (built between 1929 and 1934). This was a line of steel and concrete fortifications stretching from Belgium to Switzerland and was called ‘a gate without a fence’ because Germany would be able to avoid it and invade France via Belgium. France remained passive without Britain’s support.
Britain was sympathetic towards Germany and even signed an Anglo German naval Treaty (June 1935) allowing Germany’s navy to be 35% of the size of the Royal Navy. Hitler used his new found arms to support Franco in the Spanish Civil War (1936-9) Hitler sent the Condor Legion of the Luftwaffe to bomb Guernica on 26th April, 1937. Guernica was razed to the ground and Franco went on to conquer the Basque areas of Spain. Hitler had used Spain as a practise ground.
2. The Remilitarization of the Rhineland (1936)
Having broken the Treaty of Versailles once, Hitler risked doing it a second time by marching 30,000 troops into Cologne on 7th March 1936. France, with 250,000 troops mobilised, remained passive because Britain would not support her. Britain took the view that Germany was ‘marching into her own back yard.’
To show that his remilitarization was popular, Hitler held a plebiscite, which showed that 98.8% were in favour. He went on to build his own defensive fortification, the Siegfried Line.
3. The Rome Berlin Axis (October 1936)
Originally Mussolini did not want to be Hitler’s ally and in 1935 talks were held with Britain and France at the Stresa Front, but these came to nothing when Anthony Eden of Britain threatened oil sanctions against Mussolini during the Abyssinian crisis. This caused the Rome-Berlin Axis in 1936. Mussolini and Hitler strengthened their alliance on two occasions
4. Britain’s policy of Appeasement (May/June 1937 – March 1939)
Neville Chamberlain became British Prime Minister on 28th May 1937, and followed the policy of appeasing Germany, believing that all Hitler wanted to do was unite German speaking people. In so doing, Hitler would break the Treaty of Versailles (28th June 1919) but Chamberlain did not believe Hitler would cause war. Churchill disagreed, citing Mein Kampf (1924) where Hitler had written that Germany must regain lands ‘in the East … by the power of the sword.’
Chamberlain had misinterpreted Hitler’s aims. (We have the benefit of hindsight.)
5. The Anschluss with Austria (13th March, 1938)
Austrian Fascists wanted to unite with Germany but Schuschnigg, the Austrian Chancellor, wanted Austria to be independent. He was unable to gain support from abroad (France and the Little Entente) so agreed to meet Hitler in Berlin. He was persuaded to accept Hitler’s henchman Seyss-Inquart as Minster of the Interior. Rioting in Vienna increased under Seyss-Inquart’s leadership and Schuschnigg resigned. Seyss-Inquart invited Hitler to assist him and on 13th March, 1938 troops from the Wermacht entered Austria. In a plebiscite on the Anschluss a vote of 99.75% in favour was recorded. This was ‘rigged’ by biased questioning. Hitler made it seem that he had been invited into Austria, in fact he had incited the union.
6. Hitler Gained the Sudetenland (29th September, 1938)
The Sudetenland was lost by Austria in the Treaty of St. Germain (10th September 1919) and hereby Czechoslovakia gained 3 million German speaking people. After the Anschluss the Sudeten German leader, Konrad Henlein, demanded a union with Germany. Unable to receive help from France, the Czech Premier, Benes, mobilised alone. Fearing war, Chamberlain met Hitler on three occasions at Berchtesgaden, Godesburg and at Munich.
Munich Agreement (29th September, 1938)
This was signed by Hitler, Mussolini, Chamberlain and Daladier. Benes was not present. It said:
On his return to England, Chamberlain announced that he had gained ‘peace with honour, peace in our time’. The majority rejoiced, except Churchill.
In public Hitler seemed satisfied, but in private he exploded saying ‘that fellow Chamberlain has spoiled my entry into Prague.’
7. The Fall of Czechoslovakia (March 1939)
In March 1939, Hitler forced Lithuania to give him Memel where most people spoke German. So far Hitler had only taken German speaking territory, so Chamberlain could still appease Hitler. However, in March 1939, Hitler threatened to bomb Prague, so the Czechs surrendered. Chamberlain realised appeasement had failed, so he began to rearm Britain and guarantee peace in Poland.
8. Nazi-Soviet Pact (29th August, 1939)
By the summer of 1939, Hitler’s plans to invade Poland were complete. He realised that to invade Poland mighty cause Britain to attack him from the West but he was more concerned to avoid a Russian attack from the east. Therefore to avoid a war on two fronts, he arranged the Nazi-Soviet Pact, which said that if either country went to war the other would remain neutral.
Hitler gained the chance to invade Poland with a war on one front, if Britain supported Poland.
Stalin of USSR gained time to rearm in case Hitler attacked him later, and the chance to gain the eastern half of Poland. This would provide the USSR with a bufferzone.
9. German Invasion of Poland (1st September, 1939)
German tanks invaded West Prussia and Posen on the 1st September 1939 using blitzkrieg tactics. (This is a lightning, sudden attack co-ordinating air, then land forces). Chamberlain sent an ultimatum (a warning with a threat) saying that if Hitler did not withdraw from Poland by 11am, 3rd September 1939, Britain would declare war. On 3rd September, Britain, followed by France, declared war on Germany.
In conclusion, World War II was not an extension of World War I, but world war I was a big cause of World War II. Most of the causes of World War II came out of the Treaty of Versailles, and if that treaty had been better there might not have been world war II. Nevertheless, world war II happened and we can only learn from the mistakes we see from the past.
