It is often assumed that Sir Lewis Namier and Sir Herbert Butterfield demolished the ‘Whig interpretation of history’. In fact, much was allowed to remain standing by their failure to offer a new synthesis of English party politics. In this book Dr Clark provides the key component for such a new synthesis by a detailed exposition of the crisis of the 1750s, which was instrumental in the destruction of the party system and the emergence of new practices in the multi-factional world. The Court v. Country analysis of the politics of c. 1714–1760, still widely current, is refuted by a demonstration of the survival of the Whig and Tory parties of Queen Anne’s reign until the 1750s; the long debate about George III and the constitution is set in a new perspective; and major new insights are offered into the nature of party and party politics.
