"Ah, well," an American visitor is said to have soliloquized on the site of the battle of Hastings, "it is but a little island, and it has often been conquered." We have in these few pages to trace the evolution of a great empire, which has often conquered others, out of the little island which was often conquered itself. The mere incidents of this growth, which satisfied the childlike curiosity of earlier generations, hardly appeal to a public which is learning to look upon historical narrative not as a simple story, but as an interpretation of human development, and upon historical fact as the complex.
