Ever since the Berlin blockade of 1948 the attention of historians of modern and recent international relations has been engaged by the problem of how Germany and its capital, Berlin, came to be divided, first among the major powers of the anti-Hitler Grand Alliance—Great Britain, the United States, the Soviet Union, and France—and then, in 1949, into two rival states, the German Democratic Republic and the Federal Republic of Germany. This problem lies at the heart of the much-debated question regarding the origins of the Cold War. This review article makes no pretense at being a comprehensive report on the literature of the German problem. My aim is, rather, to call attention to some recent contributions to the literature and place them in context.
