Book excerpt: The French Émigrés in Europe and the Struggle against Revolution, 1789-1814 underlines, for the first time, the achievements rather than the failures, of the Émigrés. Different specialist essays describe their impact from London to Hungary, from Lisbon to Prussia, and confirm their critical importance in the politics, ideology and culture of their time. The French Émigrés were more than refugees, they were active, and often remarkably successful, agents on the European struggle against the French Revolution.
