This definitive study provides a comprehensive diplomatic history of Poland during the most seminal period in its existence, when its destiny lay in the hands of France, Great Britain, and the United States. Although sovereign in principle, Poland was little more than an object of the Great Powers' politics and rapidly changing relationships from the end of WWI to the end of WWII. Focusing on the shifting policies of the Great Powers toward Poland from the Treaty of Versailles to Yalta, the book ends with Poland's tragic abandonment by the West into the hands of the Soviet Union. Enriched by unique anecdotal and archival material, this book will be essential reading for all those seeking to understand Poland's role in twentieth-century history.
