To what extent can the Treaty of Versailles be blamed for WW2?
The arguments that point to the Treaty of Versailles:
The treaty shocked and angered all Germans
It shocked many other contemporaries too
Hitler gained support because he condemned the treaty and promised to destroy it
By rearming, remilitarising the Rhineland and joining with Austria he did as he had promised
And by getting away with it he went further (the Sudetenland and Czechoslovakia)
He then turned his attention to Poland and that led to WW2
We can also add that the successor states created by the treaty, eg Poland and Czechoslovakia, were not made strong enough to resist a revitalised Germany
Other factors that must also be considered:
British Appeasement (though this is also linked to the treaty)
The Nazi-Soviet Pact
The treaty could have been revised peacefully (something Stresemann had done to some extent)
Hitler’s policy of lebensraum was not directly related to the treaty
Neither was his racially motivated disregard for Slavs
