How successful was the Congress of Vienna (1814-1815) at creating a stable Europe in the long term (until 1850)?
TIP: First analyze the challenges that the Congress of Vienna attempted to address. Then discuss the underlying principles of the Congress: legitimacy, equilibrium, compensation, and conservatism. The body of your essay should discuss the ways in which these principles were followed or ignored, in practice, by considering how the balance was restored to Europe and whether future security ensured.
