The student who would attempt such a problem as this must be familiar with the outlines of English constitutional development, but he must also be prepared to banish from his mind all prejudices and prepossessions derived from such knowledge. For he will find here no record of liberty slowly broadening from precedent to precedent, no statesmen kings, surrounded by sagacious advisers, defining the scope and the purpose of a legal system, no patriotic barons, banded together to wrest from an unwilling monarch a power which was not being wielded for the national good, no common aim uniting reformers of the thirteenth century with reformers of the seventeenth. He can name here no great names in the progress of constitutional freedom or in the growth of a consistent system of law; Scotland produced no Henry the Second, no Simon de Montfort, no Edward the First, no Hampden and no Sydney. He must divest himself of the atmosphere of English history and be prepared to find a separate people, affected by influences widely different, and responding to impulses clearly divergent from the familiar movements of English history. The story is not without its heroes, but they are of a wilder and more romantic type than in England. James I, throwing himself bravely and fiercely against the system of abuses which he found in Scotland, and paying with his life for his courage and devotion, is a constitutional hero utterly unlike a Henry or an Edward. This aspect of Scottish history is the less interesting and the less definite because it is so largely impersonal; there are many famous names in the political and in the ecclesiastical story of Scotland, but few indeed lend themselves to brighten the pages that tell of constitutional development. It is, perhaps, for this reason that historians have left it alone. Writers on Scottish history from Boece and Major to Tytler and Hill Burton have ignored its existence; even the learned editors of such constitutional documents as the Privy Council Register and the Treasurer's Accounts have been pre-occupied by the varying scenes of the political drama, and are largely silent on questions relating to the constitution.[1] The conditions of government, justice, and finance before the reign of Malcolm Canmore, and the relations of the king to his seven mormaers or earls, are unexplored mysteries. Not less difficult are the questions that relate to the next period. How did the burghs come into being, and whence did they derive that system of law and custom which was administered by the Four Burghs and the Hanse Burghs, and which even Edward I was unable to ignore? How did the clan-system of the tenth century pass, in the Lowlands, into the family-system of the twelfth? Who were the good men who formed the community of the kingdom, and on whose advice the kings granted charters and liberties? What was the real signification of these charters themselves, and what privileges did they confer? What was
