Which of these leaders succeeded Usman dan Fodio as the head of the Sokoto Caliphate?

The leader who succeeded Usman dan Fodio as the head of the Sokoto Caliphate was Muhammadu Bello. Usman dan Fodio was a prominent Islamic scholar and founder of the Sokoto Caliphate in the early 19th century in what is now northern Nigeria. After his leadership, his son, Muhammadu Bello, took over the reins of the caliphate.

Muhammadu Bello was instrumental in consolidating the achievements of his father and further expanding the territory and influence of the Sokoto Caliphate. He was known for his administrative skills and efforts to develop the caliphate into a region with strong Islamic governance.

To further clarify:

• Umar Tall was a West African leader, but he was associated with the Toucouleur Empire, not the Sokoto Caliphate.
• Al-Kanemi was a leader in Borno and opposed the Sokoto forces, not a successor in the Sokoto Caliphate.
• Muhammad al-Amin is another historical figure associated with the Borno region, not the Sokoto Caliphate.
