This paper is the first fruit of a study of electoral politics in the Borough of Cambridge between the first and second Reform Bills, in which we are attempting to explore in detail some of the most important general questions about the political history of mid-Victorian Britain.

The critical importance of the period between 1832 and 1868 to the transition from aristocratic rule to parliamentary democracy in Britain is not in doubt. In the terms of the most useful comparative study (Lipset and Rokkan 1967) 1832 represented an early, genuine but limited concession by the old elite to bourgeois and working class claims to political influence, a remarkably Whig view. The major works on the politics of the period (esp. Gash 1933 and Hanham 1959) have emphasised the limited nature of the concession while other have thrown doubt on the notion of concession, at all, pointing out the conservative intentions behind the First Reform Bill (Moore 1966, 1976) and the contingent pressures on the actual provisions of the Second (Cowling 1967). Control of Parliament remained largely where it had been before; the decline of aristocratic government was long drawn out; adaptation of the political system followed slowly in the wake of economic and social change. Middle class reform and militant labour were gradually accommodated in the parliamentary system, enlisted in the ranks of the aristocratic parties, which though transformed, even now, moderate, loyal, constitutionalist, bear the marks of their origin. Part of the explanation for the success of gradualism must be sought in the weakness of the labor movement and its failure at the revolutionary moment, which has been illuminated in detail by Foster's studies of industrial towns (1967, 1968, 1974).
