This article explores how ideas of patriarchy have shaped the nature and effect of rape law. It argues that rape law reinforces patriarchy, and because of the inherent inconsistencies between the male roles of aggressor and protector, it has remained ineffective. Taking Kenya as its springboard, it analyses how ideas of sexual relations within and outside marriage are transplanted through colonialism; and how they morph and merge with analogous indigenous conceptions to entrench and formalise the continued subjugation of the female body. It explores the unintended consequences of the internationalisation of English Monogamy; and rape law reform and its continuity/discontinuity with the Civilising Mission
