Many historians, including Ellen Ross, Shani D'Cruze, and James Hammerton, have explored domestic abuse in the working class 2. Though their approaches differ, these historians share one assumption-that married couples and cohabiting couples were virtually indistinguishable. In many ways, historians are justified in doing this, since long-term cohabitees did share many of the experiences of those legally wed, both socially and legally. But these similarities can be overstated; cohabitees had peculiarities all their own. The motives and justifications for violence show that for many couples, cohabitation was similar to marriage, yet did not have its security or legal status. The irregular status of the couple compounded the well-known strains of living together in poverty and with strongly gendered expectations. The Victorian courts, too, struggled with the problem of applying marital expectations to non-marital couples; the results could be contradictory decisions and conflict between judges and juries. Ironically, in an age in which many couples could not marry legally, the courts held couples, but especially men, to middle-class domestic standards. 2 I will base my conclusions on a sample of 217 violent incidents within cohabiting families culled fromthe Yorkshire Gazette, Lancaster Guardian, and London Times between 1850 and 1905. To find this sample, I read through all the issues of the Yorkshire Gazette and the Lancaster Guardian (both weeklies) in ten separate years between 1850 and 1905, finding the cases in police reports, assize reports, and magistrates' court reports. For the Times, which as a daily had far more issues, I limited myself to reading the police, assize, and Old Bailey reports for four months (March-April and August-September) in nine separate years between 1853 and 1893 3. I also included cases from other sources, such as criminal appeals casebooks, and supplemented The Times with reports in local newspapers whenever possible. I then looked up all the relevant Old Bailey and Home Office files, in
