In 1910-1940, the success of Hamallist Information Networks to beat the French imperial machinery in the Nioro of the Sahara located in the French Sudan (known as Mali nowadays), leads to reconsidering the power relationship organizing the authority and the challenge to establish the authority relation during colonial period. That calls into question the idea of a sole and unique domination by French imperialism during colonization and at the same time, it indicates that indigenous people were very active in the historical processes, which determined their existence.展开更多
