The use of child soldiers violates human rights and international norms, yet children continue to be abused as soldiers, human shields, and they are forced to participate in armed conflicts worldwide. This is shown to impact the children in many ways and therefore they need extra help when leaving the armed groups. The reintegration process is often part of countries' Disarmament, Demobilization, and Reintegration (DDR) programs and is crucial for both the children's and the country's future. This study aims to examine the reintegration of former childsoldiers in Sierra Leone and northern Uganda. By comparing and analyzing the processes and outcomes in these two countries using existing materials, this study highlights key aspects of reintegration. By using the social integration theory and focusing on the factors of family, school, and religion, this study compares and analyzes the two cases. The results indicate that while both Sierra Leone and northern Uganda have engaged in the reintegration of childsoldiers, their approaches differ. Sierra Leone has demonstrated a more effective process concerning school and family reintegration, whereas northern Uganda has placed greater emphasis on the role of religion, despite efforts to provide both educational opportunities and familial connections for the children.
