*152. Whigs and Tories.*--The seventeenth-century origins of political parties in England, the development of Whigs and Tories following the Revolution of 1688-1689, and the prolonged Whig supremacy during the reigns of George I. and George II., have been alluded to in another place.[211] During the eighteenth century the parliamentary system was but slowly coming into its own, and again and again party lines all but disappeared. The recurring rivalry of Whig and Tory elements, however, brought about gradually a habitual recognition of the responsibility of ministers, and this responsibility, in turn, reacted to accentuate party demarcation. The efforts of George III. to revive the royal prerogative had the effect of calling into existence a body of new Tories, not Jacobite, but Hanoverian, who supported the king in his purpose, and at the same time, of driving the forces of opposition to a closer union and more constant vigilance. Throughout the century the tone of party politics was continuously low. Bribery and other forms of corruption were rife, and the powers of government, both national and local, were in the hands regularly of an aristocratic minority which ruled in its own interest. The high-water mark of intrigue was reached in 1783 when the old Tories, led by Lord North, allied themselves with the old Whigs, led by Charles James Fox, to retain power and to curtail the influence of the king. The coalition was unsuccessful, and the defeat of Fox's India Bill, in December, 1783, became the occasion of the younger Pitt's elevation to the premiership, followed within three months by a national election which precipitated an end of the seventy years of Whig ascendancy.
