evidence: Since independence from British colonial rule, large numbers of South Sudanese and Ugandans have repeatedly crossed the shared border to escape civil wars. These forced movements of large populations have created shifting labels of ‘refugees’ and ‘internally displaced persons’ (IDPs), with tremendous social, economic and political repercussions for the persons to which these labels are applied. [...] Different ethnic groups that have seen clashes over contested territories have also been forced into settling in areas of close proximity following unrest in their respective homelands. My own research reveals the Kuku of Kajokeji in South Sudan were so suspicious of the Madi in the Ugandan Moyo district that, when they settled in the latter’s region, they avoided treatment in the Moyo hospital for fear of maltreatment by Madi medical personnel. The history of conflict over certain borders has a direct bearing on the welfare of refugees in the present.
