How did the Sokoto caliphate organize its central government?

Usman dan Fodio sought to establish a simple, non-exploitative administrative system for the Sokoto caliphate. His vision for the central government, as outlined in his treatise Bayān wujūb al-hijra, included a limited bureaucracy consisting of a loyal vizier, judges, a chief of police, and a tax collector.1

The caliphate’s governance was structured as follows:

• Central Authority: The caliph, titled amīr al-muʾminīn ("commander of the faithful"), held supreme authority. In 1812, the administration was reorganized, with the caliph’s viziers, Abdullahi dan Fodio and Muhammad Bello, taking responsibility for the western and eastern sectors, respectively.12
• Local Administration: Regional governance was managed by emirs selected from the scholarly class, chosen specifically for their piety, learning, integrity, and commitment to justice.1
• Autonomy and Oversight: While individual emirates maintained autonomy, they pledged loyalty to the central authority in Sokoto and contributed to its upkeep. Disputes within or between these emirates were referred to Sokoto for resolution, with officials traveling to oversee regional developments.2
