Correct Option: D. Gwandu Detailed Explanation: The Sokoto Caliphate, established in the early 19th century by Usman dan Fodio, was a significant Islamic state in what is now northern Nigeria. It was divided into various administrative zones, each governed from key cities. Understanding the administration of the western zone of the Sokoto Caliphate requires knowledge of its historical context and the roles of the cities mentioned in the options.

1. Historical Context:
2. The Sokoto Caliphate was formed as a result of a jihad (holy war) aimed at reforming Islam and establishing a more orthodox Islamic state. It expanded rapidly and included various regions, each with its own local governance structures.
3. The caliphate was divided into provinces, each overseen by an emir who reported to the Sultan of Sokoto.
4. Role of Gwandu:
5. Gwandu was one of the key cities in the Sokoto Caliphate and served as the administrative center for the western zone. It was strategically located and played a crucial role in the governance and organization of the caliphate.
6. The city was known for its educational institutions and was a hub for Islamic scholarship, which further solidified its importance in the administration of the caliphate.
7. Why Gwandu is Correct:
8. Gwandu was specifically designated as the administrative center for the western zone, making it the correct answer. The emir of Gwandu had significant authority and was responsible for the governance of the surrounding areas, including Kebbi and Ilorin.

Analysis of Other Options:

• A. Kebbi:
• While Kebbi was an important region within the Sokoto Caliphate, it was not the administrative center for the western zone. Instead, it was governed under the authority of Gwandu. Kebbi had its own emir but was subordinate to the emir of Gwandu.
• B. Ilorin:
• Ilorin was a significant city, especially in the context of the Yoruba and Fulani interactions. However, it was not the administrative center of the western zone of the Sokoto Caliphate. It was more of a frontier city and had a different political structure, often influenced by the Oyo Empire.
• C. Bida:
• Bida was the capital of the Nupe Kingdom and was not part of the Sokoto Caliphate's western zone administration. It was a separate entity with its own governance and was not directly administered from Gwandu.

Summary of Key Points:

• The western zone of the Sokoto Caliphate was administered from Gwandu, which served as the key administrative center.
• Gwandu was strategically important for governance and Islamic scholarship within the caliphate.
• Other options like Kebbi, Ilorin, and Bida were significant but did not serve as the administrative center for the western zone.
• Understanding the historical context and the roles of these cities is crucial for grasping the administrative structure of the Sokoto Caliphate.

Revision Summary:

• Gwandu was the administrative center of the western zone of the Sokoto Caliphate.
• The caliphate was divided into provinces, each governed by an emir.
• Kebbi and Ilorin were important regions but not administrative centers for the western zone.
• Bida was a separate kingdom and not part of the Sokoto Caliphate's administration.
