There is an explicit link between the historical evolution of migratory movements, their social and economic significance, the various phases of the development of states and the stability of the relationships between individuals and states sharing common borders. The starting point of this study is motivated by the denaturalization of reality by political actors through inappropriate responses, based on mixed considerations of the migrations of Rwandans and of Hutu or Tutsi peoples living in the DRC compared to Ugandan nationals. On the one hand, most of them move between these three states and invade agro-pastoral and mining lands in fertile or mining areas, especially in the DRC. Our study aims to identify the causes of the persistence of the crises between the DRC, Uganda and Rwanda, which crises are linked to the multiple migratory movements of their respective nationals. In practical terms, we will determine the characteristics of the migratory movements between the three states and present the causes of this persistence of the crises. We have identified direct and indirect causes, among which uncontrolled migration by clandestine routes constitute a major cause of the security crises between these three states.

Since the 1960s, whenever a conflict has occurred in one of the states of the great lakes’ region of Africa, the balance of neighboring countries has also been threatened. The efforts were made by public and private actors, among others the institutions of these states, international un animators and civil society actors (national, international NGOs, independent actors). And between 2003 and 2006, to restore peace to the region, these efforts resulted in the formal cessation of hostilities and the engagement of countries in the region in the peacebuilding process. All the countries of the region, in particular the Democratic Republic of the Congo and Uganda, still face social injustice, the lack of democracy as well as the problem of managing the border areas essential to maintain a lasting peace. Through this study, we would like to address the situation of the border conflict between the Democratic Republic of the Congo and Uganda. And therefore, we will discuss the different approaches to the analysis of this conflict, the character, the actors, the factors, the challenges and evaluate the various attempts to end the crisis already made.
