smaller in population and less economically vibrant than Germany. Barnett concludes by saying that instead of weakening Germany, the treaty "much enhanced" German power. Britain and France should have (according to Barnett) "divided and permanently weakened" Germany by undoing Bismarck's work and partitioning Germany into smaller, weaker states so it could never have disrupted the peace of Europe again. By failing to do this and therefore not solving the problem of German power and restoring the equilibrium of Europe, Britain "had failed in her main purpose in taking part in the Great War". The British historian of modern Germany, Richard J. Evans, wrote that during the war the German right was committed to an annexationist program which aimed at Germany annexing most of Europe and Africa. Consequently, any peace treaty that did not leave Germany as the conqueror would be unacceptable to them. Short of allowing Germany to keep all the conquests of the Treaty of Brest-Litovsk, Evans argued that there was nothing that could have been done to persuade the German right to accept Versailles. Evans further noted that the parties of the Weimar Coalition, namely the Social Democratic Party of Germany (SPD), the social liberal German Democratic Party (DDP) and the Christian democratic Centre Party, were all equally opposed to Versailles, and it is false to claim as some historians have that opposition to Versailles also equalled opposition to the Weimar Republic. Finally, Evans argued that it is untrue that Versailles caused the premature end of the Republic, instead contending that it was the Great Depression of the early 1930s that put an end to German democracy. He also argued that Versailles was not the "main cause" of National Socialism and the German economy was "only marginally influenced by the impact of reparations". Ewa Thompson points out that the treaty allowed numerous nations in Central and Eastern Europe to liberate themselves from oppressive German rule, a fact that is often neglected by Western historiography, more interested in understanding the German point of view. In nations that found themselves free as the result of the treaty — such as Poles or Czechs — it is seen as a symbol of recognition of wrongs committed against small nations by their much larger aggressive neighbours. Resentment caused by the treaty sowed fertile psychological ground for the eventual rise of the Nazi Party, but the German-born Australian historian Jürgen Tampke argued that
