*33. Elements of Stability and Change.*--Structurally, the English governmental system was by the close of the seventeenth century substantially complete. The limited monarchy, the ministry, the two houses of parliament, the courts of law, and the local administrative agencies were by that time constituted very much as they are to-day. The fundamental principles, furthermore, upon which English government is operated were securely established. Laws could be enacted only by "the king in parliament"; taxes could be levied only in the same manner; the liberty of the individual was safeguarded by a score of specific and oft-renewed guarantees. In point of fact, however, the English constitution of 1689 was very far from being the English constitution of 1912. The overturn by which the last Stuart was driven from the throne not only marked the culmination of the revolution commenced in 1640; it comprised the beginning of a more extended revolution, peaceful but thoroughgoing, by which the governmental system of the realm was amplified, carried in new directions, and successively readapted to fresh and changing conditions. At no time from William III. to George V. was there a deliberate overhauling of the governmental system as a whole. Save in occasional parliamentary enactments and judicial decisions, the constitutional changes which were wrought were rarely given documentary expression. Yet it is hardly too much to say that of the principles and practices which to-day make up the working constitution of the United Kingdom almost all were originated or reshaped during the eighteenth and nineteenth centuries. In describing, in succeeding chapters, the principal aspects of this governmental system it will be necessary frequently to allude to these more recent constitutional developments, and it would but involve repetition to undertake an account of them at this point. An enumeration and a brief characterization of a few of the more important will serve for the moment to impress the importance constitutionally of the period under consideration.
