This article analyses convicted cases of annuity fraud published in the Old Bailey Criminal Court journal, The Proceedings, from 1766-1800. These cases were identified using digital research methods and the online database “The Proceedings of the Old Bailey, 1674-1913”. Defendants were found guilty on counts of forgery and personation in attempting to steal Bank of England annuities or annuity dividends. Annuity fraud was a specific type of securities fraud that often involved impersonation or what we might today call “identity theft”. This underexamined area of crime history is analysed in relation to the consumer revolution in eighteenth-century England.
