Most famously , the Treaty of Versailles itself weakened Germany 's military and placed full blame for the war and costly reparations on Germany 's shoulders -- the humiliation and resentment in Germany is sometimes considered one of the causes of Nazi electoral successes and indirectly a cause of World War II .

Republican Germany was not invited to attend the conference at Versailles . Representatives of White Russia ( but not Communist Russia ) were present . Numerous other nations did send delegations in order to appeal for various unsuccessful additions to the treaties ; parties lobbied for causes ranging from independence for the countries of the South Caucasus to Japan 's unsuccessful demand for racial equality amongst the other Great Powers . </P>
