__________ was a major factor that contributed to the rise of the Sokoto Caliphate.

Step 1: Analyze the question The question asks for the major factor that led to the rise of the Sokoto Caliphate, which was founded in the early 19th century in Hausaland (northern Nigeria).

Step 2: Explain the concept The Sokoto Caliphate was created through the Fulani Jihad (1804-1808) led by Usman dan Fodio, a Fulani Islamic scholar. He was unhappy with the way the Hausa rulers governed, citing:

• Heavy and unjust taxation
• Corruption and oppression of the common people
• Mixing Islam with traditional (pagan) practices (syncretism)
• Enslaving free Muslims

He preached reform, gathered followers, and when the ruler of Gobir (Yunfa) turned against him, he declared a jihad. After the jihad succeeded, the Hausa states were united under a single Islamic empire, with its capital eventually at Sokoto. Flag bearers were appointed as emirs to rule various territories.

Step 3: Evaluate the options

• A. Agricultural revolution: There was no such revolution that triggered the caliphate's rise.
• B. Slave trade: The caliphate later used slave labour, but it was not the cause of its founding.
• C. European colonization: This came later. The British conquered the caliphate in 1903, so it ended the caliphate rather than creating it.
• D. Islamic Jihad: This was the direct cause. The jihad was the movement that established the caliphate.

Step 4: Answer The correct answer is D. Islamic Jihad.

Tip: Remember the chain: Usman dan Fodio → Jihad (1804) → Sokoto Caliphate. Whenever you see "Sokoto Caliphate" and "rise" in a question, think of the jihad. Also remember that colonization (1903) marks the fall, not the rise.
