Confréries et pouvoir. La Tījānīyya Hamāwiyya en Afrique occidentale (Burkina Faso, Côte d'Ivoire, Mali, Niger) : 1909-1965 The shaykh Sidi Mohammad Ben Abdallah, also known under the name shaykh Lakhdar was the initiator of the eleven jawaharatu-l-kamali prayer of the tijaniyya muslim group at nioro du Sahel in the former french Sudan. That was in 1909. This singular branch of the tijaniyya is also linked to the name of the shaykh Hamahoullah or Hamallah who was the follower and the successor of the shaykh Lakhdar. From the political point of view, the emergence of the hamawiyya or hamallisme, squares with the setting up of the colonial administration after the conquest, and from the religious point of view, to the end of the jihad and the acceptance of the colonial situation by many muslim leaders. The refusal by the shaykh Hamahoullah of a colonial compromise and the activities of the hamawi, placed the tijaniyya hamawiyya in a warring situation against the french administration between 1925 and 1948. Following a conflict between several moorish tribes in the nioro and assaba districts in august 1940, the colonial administration took the advantage to put down the hamawiyya. This resulted in the confinement of the hamawiyya top leaders in various african prisons and in the death in prison in january 1943 of Hamahoullah. However, the hamawi took the advantage of the decolonization process in the late 1940s with the creation of political parties to develop new prospects and move towards the urban centres. In the post-colonial states, the attitude of tijaniyya hamawiyya zealots is devided between the reconciliation with the national umma and a rigid moralist position which would give it the image of a fundamentalist sect.
