The Congress of Vienna was a success because they did complete their MAJOR goal of getting France to lose some of their territory.However even though  they couldn't exclude them from some of the negotiations because France allied with Spain,Sweeden, and Portugal and used them even though they were minor countries in the treaty France used them to get what they wanted.In my opinion France was very sneaky and inteligent because even though they were excluded  they weaseled theirselves back into negotiations by using Spain,Sweeden, and Portugal .
