Since the 1950s, historians of the eighteenth- and nineteenth-century Church of England have generally maintained that the Sacramental Test Act (1828), the Roman Catholic Relief Act (1829) and the Reform Act (1832) amounted to a ‘constitutional revolution’, in which Anglican political hegemony was decisively displaced. This theory remains the dominant framework for understanding the effect of legislation on the relationship between church and state in pre-Victorian England. This article probes the validity of the theory. It is argued that the legislative reforms of 1828–32 did not drastically alter the religious composition of parliament, which was already multi-denominational, and that they incorporated clauses which preserved the political dominance of the Church of England. Additionally, it is suggested that Anglican apprehensions concerning the reforming measures of those years were derived from an unfounded belief that these reforms would ultimately result in changes to the Church of England's formularies or in disestablishment, rather than from the actual laws enacted. Accordingly, the post-1832 British parliamentary system did not in the short term militate against Anglican interests. In light of this reappraisal, these legislative reforms may be better understood as an exercise in ‘constitutional adjustment’ as opposed to a ‘constitutional revolution’.
