The central focus of the book is Russia, and the rise and fall of the Tsarist and the Soviet Empires. The overwhelming majority of works on empire concentrate on the European maritime powers. Lieven's comparative approach highlights the important role played by Russia in the expansion of Europe and its rise to global dominance. The book contrasts the nature, strategies, and fate of empire in Russia with that of its major rivals, the Habsburg, Ottoman, and British empires, and considers a broad range of other cases from ancient China and Rome to the present-day United States, Indonesia, India, and the European Union.

Many of the dilemmas of empire persist in today's world, and Lieven throws new light on some of the most intractable current examples, including the crisis in the former Soviet Union, the troubles in Ulster, and ethnic cleansing in the Balkans. This major examination of the imperial experience presents history on the grandest scale, combining formidable erudition with stimulating readability.
