<P> Abjectivication through discourses of dirt and sanitation are used to draw distinctions between the Western governing figures and the local population . Dirt being seen as something out of place, whilst cleanliness being attributed to the "in group", the colonisers, and dirt being paralleled with the indigenous people . The reactions of disgust and displeasure to dirt and uncleanliness are often linked social norms and the wider cultural context, shaping the way in which Africa is still thought of today . </P> <P> Brown discusses how the colonial authorities were only concerned with constructing a working sewage system to cater for the colonials themselves, and weren't concerned with the Ugandan population . This rhetoric of sanitation is important because it is seen as a key part of modernity and being civilised, which the African population are therefore seen as not being . This lack of sanitation and proper sewage systems add to this discourse of the people of Africa and Africa itself being savages and uncivilised, playing a central role in how the west justified the case of the civilising process . Brown refers to this process of abjectification using discourses of dirt as a physical and material legacy of colonialism that is still very much present in Kampala and other African cities today . </P> <P> Critical theory on the colonisation of Africa is largely unified in a condemnation of imperial activities . Postcolonial theory has been derived from this anti-colonial / anti-imperial concept and writers such as Mbembe, Mamdani and Brown, and many more, have used it as a narrative for their work on the colonisation of Africa . </P> <Dl> <Dd> <Dl> <Dd>' Post colonialism can be described as a powerful interdisciplinary mood in the social sciences and humanities that is refocusing attention on the imperial / colonial past, and critically revising understanding of the place of the west in the world .' </Dd> </Dl> </Dd> </Dl>
