Colonial policies and practices were very instrumental in the creation of the Luo Diaspora. This Diaspora extended far beyond the physical and cultural boundaries of Central Nyanza as was constituted by the colonial administration. To colonial officials, this Diaspora represented ‘detribalized natives’ responsible for social decay and immorality in the colonial townships. Similarly, to the male elders in the rural areas, this Diaspora was an affront towards destabilizing tribal authority and sanctions, which governed Luo moral order, Luo marriage, and Luo identity as it existed prior to colonialism. This article uses patriarchy as an analytical framework to understand how male elders and colonial officials collaborated to assert control over young women under suspicion of prostitution. The article argues that the Ramogi African Welfare Association (RAWA) was a post-war patriarchal institution which was used by male elders, with the encouragement of the colonial officials, to intimidate, harass and repatriate young women seeking wage employment within the emerging colonial townships. In this article, I use archival and field data gathered from Central Nyanza between 1999 and 2002 to illustrate how institutionalized patriarchy threatened many women and young girls seeking to migrate to colonial towns in order to exploit the limited economic and social opportunities that colonialism provided
