At every stage, The Isles connects offshore development with parallel events on the Continent. This richly layered history begins with the Celtic Supremacy in the last centuries BC, which is presented in the light of a Celtic world stretching all the way from Iberia to Asia Minor. Roman Britain is seen not as a unique phenomenon but as similar to the other frontier regions of the Roman Empire, such as Germany. The Viking Age is viewed not only through the eyes of the invaded but from the standpoint of the invaders themselves -- Norse, Danes, and Normans. Plantagenet England is perceived, like the Kingdom of Jerusalem, as an extension of medieval France. In the later chapters, Davies follows the growth of the United Kingdom and charts the rise and fall of the main pillars of Britishness -- the Royal Navy, the Westminster Parliament, the Constitutional Monarchy, the Aristocracy, the Protestant Supremecy, the British Empire, the imperial economy and sterling area, and the English Language. The book ends with the crisis confronting Britain now -- the emergence of the European Union. As the elements that make up the Isles dissolve, Davies shows how public confusion is one of the most potent factors in this process of disintegration. He predicts that the coming crisis in the British State may well be its last.

This integrationist approach challenges the traditional nationalist picture of a thousand years of"eternal England" -- a unique country formed at an early date by Anglo-Saxon kings which evolved in isolation and, except for the Norman Conquest, was only marginally affected by continental affairs. The result is a new picture of the Isles, one of four continents -- England, Ireland, Scotland and Wales -- constantly buffeted by continental storms and repeatedly transformed by them. Illuminated by the same clarity and piercing originality that distinguished Europe: A History, The Isles will become an agenda-setting book, one that will encourage a reassessment of what it means to be British while sparking debate about ideas of national identity and sovereignty.
