This dissertation aims to understand, in general, dynamic political, social and economic of the Congo in the late eighteenth century. Based on reports of European missionaries, this research aims to deepen the dynamics between the provinces of the kingdom and the central power and how congolese elite will use relations with the Europeans to politically assert in the region. Questioning the sphere of power exercised by the king in this historical period and the circulation of political and religious knowledge and practices. Europeans, especially the missionaries sought to map this company so that it would fit the political mold, social and religious established by them, based on the concepts of kingdoms and empires, so that might have failed to understand the current political and social structure of the Congo. What would appear in the eyes of the missionaries a political decentralization of Congo caused by the civil war and the consequent dismantling of the provinces could set up a characteristic of these companies in other contexts. They would be articulated through a chain of companies, in which some were encompassed and other encompassing through large spaces varied as trade, religious, linguistic and political and war.
