The lbadan Conference of 1950 was convened to discuss the provisions of the ....

Step 1: Analyze the question The question asks which constitution was discussed at the Ibadan Conference of 1950. This is a Nigerian constitutional history question, so we need to match the conference to the right constitution.

Step 2: Recall the concept Nigeria's colonial constitutions came in this order:

• Clifford Constitution (1922): introduced elective principle in Lagos and Calabar
• Richards Constitution (1946): introduced regional legislative councils (Houses of Assembly in the North, and Houses of Assembly in the West, plus the House of Chiefs in the North and West)
• Macpherson Constitution (1951): the result of widespread consultation
• Lyttleton Constitution (1954): introduced federalism

Step 3: Work through the solution The Richards Constitution was criticized for being introduced without consulting Nigerians. In response, Governor Sir John Macpherson, who succeeded Richards, started a wide consultation process. It began at the village and district levels, then moved to the provincial and regional levels. It ended with the General Conference at Ibadan in January 1950, where delegates from the three regions reviewed the proposals and recommendations.

The Ibadan Conference therefore reviewed the proposals for a new constitution, and these were the foundations of the Macpherson Constitution of 1951. It is the constitution whose provisions were discussed there and then enacted.

Step 4: Answer The Ibadan Conference of 1950 was convened to discuss the provisions of the Macpherson Constitution, which is option B.

Step 5: Exam tip Remember the sequence with the years: 1922 Clifford → 1946 Richards → 1951 Macpherson → 1954 Lyttleton. Link "Ibadan 1950" with "Macpherson 1951": the conference came just before the constitution took effect. Also remember that Macpherson's approach was consultative, going from the grassroots up to Ibadan, which is why it is remembered as more democratic than Richards'.
