From the early 1800s through the 1920s the image of the ideal domestic servant varied dramatically—native white women, European immigrant women, and black women. However, at all times the racial/ethnic identity of the domestic servant played a critical role. The transition from the casualness of “help” to the formality of the “domestic servant” relationship marked the historical moment in which a subordinate racial identity became a precondition of servanthood. The semantic change from help or hired girl to domestic servant reflected a more fundamental change in the nature, organization, and expectation of the work role. Using a comparative-historical approach, we provide a sociological analysis of how shifting labor patterns and societal demands led to the decline of help, the rise of domestic service, and the centrality of a racialized identity to the performance of household work during the nineteenth and early twentieth centuries.
