text: why was the treaty of versailles unsuccesful? or what did the leaders do to make it unsuccesful? this is for an essay so if you could list some oints or sources or anything that will help me write this the treaty was unsuccessful.they put all the blame on germany.they did not stick to their word and give italy the territories they wanted. by putting the entire blame on germany and compelling them to pay a huge war indemnity they hurt the german people who suffered during the depression.hitler was a charismatic orator who proved to the german people that the treaty of versailles was a great injustice and they followed him into war.this is how hitler was successful in arousing german nationalism,nazism and offcourse starting the second world war.  personal opinion:personally, i believe the treaty was a great bane for the germans who suffered from years of unemployment and poverty.if the conditions of the treaty were a  little more mild the germans would probably have not taken hitler upon his word.
