Invading Europe: The British army and its preparations for the Normandy campaign, 1942-44

Some scholars claim that collective security always fails. This article analyses a case where it succeeded. When Belgians rebelled against Dutch rule in the early 1830s, all five great powers agreed no fewer than four times to threaten or to use force against one or both sides. Why? Drawing extensively on diplomatic correspondence from Austrian, German and Russian archives, I show that the Concert of Europe functioned as a security regime, helping the powers to agree. Great power consensus broke down when Britain and France imposed a peace settlement on the Dutch in 1832. Yet the Belgian case—like Iraq's 1991 expulsion from Kuwait—shows that collective security can sometimes succeed against cross-border aggression.
