This article is about women's labour in nineteenth-century Abẹ́òkúta, in present-day south-west Nigeria. It is based on primary research which explores women's economic independence and its intricate connection to the indigenous institution of polygyny. By examining the institution from the perspective of Anglican Church Missionary Society evangelists, it also demonstrates how indigenous culture conflicted with the newly introduced Christian religion and its corresponding Victorian bourgeois ideals of the male breadwinner and the female homemaker. It investigates the extent to which missionaries understood women's work in the Yorùbá context, their representations of the practice, their attempts to halt female labour and their often unsuccessful efforts to extricate their congregations and their own families from these local practices. It argues that European Christian principles not only coloured missionary perceptions of women's labour, but influenced their opinions of the entire Yorùbá matrimonial arrangement.
