This article considers, with particular reference to London, the impact of legislation during the second quarter of the nineteenth century on the churches’ practice of rites of passage in relation to births, marriages and deaths. It investigates the religious, political and social reasons for legislation relating to these rites which many contemporaries and subsequent historians considered an attack on the Church of England and evidence of advancing secularization. It shows that despite significant constitutional, social and religious changes during these years, religiously motivated politicians, sympathetic to the established church, achieved legislation introducing general registration of births, marriages and deaths, and providing for more satisfactory burial of London's rapidly growing population in the context of a high death rate. While satisfying some grievances of religious Dissenters, this protected the established church's interests, and evidence suggests that a high proportion of London's population continued to access its rites of passage for baptism, marriage and burial.
