How has the Crown become such an important factor in the modern development of British peoples? The answer is not found altogether in personal considerations nor even in those of loyalty to somewhat vague and undefined principles of government. These considerations have had great weight but so also has the traditional and actual power of the Monarchy in moulding institutions and ideas during a thousand years of history. To a much greater extent than is generally understood in these democratic days has this latter influence been a factor. Through nearly all British history the Sovereign has either represented the popular instincts of the time or else led in the direction of extended territory and power under the individual influence of royal valour or statecraft. The history of England has not, of course, been confined to the biography of its Kings or Queens, but it would be as absurd to trace those annals without extended study of the rulers and their characters as it would be to write the records without reference to the people and popular progress. And the Monarchy has done much for the British Isles. Its influence has effected their whole national life in war and in peace, in religion and in morals, in literature and in art. The individual achievements and actions of some of these rulers constitute the very foundation stones in the structure of modern British power. Others again have helped to build the walls of the national edifice until the Sovereign at the beginning of the twentieth century has become the pivot upon which turns the constitutional unity of a great Empire and which forms the only possible centre for a common allegiance amongst its varied peoples.
