Mohamed Ould Cheikh Hamahoullah, popularly known as Bouyé Haïdara, is a revered Sufi leader whose influence extends across West Africa. At 84, he continues to guide millions from his zawiyah in Nioro du Sahel, Mali. As the heir to the spiritual legacy of his father, Sheikh Hamahullah, Bouyé Haïdara leads the Hamallism branch of the Tidjane brotherhood, a movement that gained prominence through its resistance to French colonialism. His following, estimated at 5-10 million talibés, testifies to the enduring appeal of Sufi traditions in the region. Bouyé Haïdara’s teachings bridge historical anti-colonial sentiment with contemporary spiritual guidance. His influence transcends religious spheres, making him a key figure in Mali’s social and political landscape.
