UPGA did not disintegrate because the East and the North went into traditional alliance at the Federal. No, UPGA was formed after NCNC and NPC fell out. The pressure for an NCNC-AG coalition started after the 1959 elections, but did not materialize then. It is noteworthy that Dr. Okpara was one of the proponents of the move. It is therefore not surprising that he went headlong for UPGA when he led NCNC. UPGA, like other political associations, died with the advent of Military Rule.
I must confess that until my stay in the North, I did not realize that the Hausas had their own culture, different from Islamic tradition. It was a student from Sokoto who led me to this realization. The onus now is on the Hausas to free themselves. The concept of Hausa/Fulani creates the impression that the Hausas are happy with being identified as Fulanis. I find this strange because throughout the history of mankind, most conquered people had always fought, in one way or the other, to regain their freedom. Perhaps, the association gave the Hausas some political advantage which is currently under threat.
I agree with you on the above. I shall hasten to add that the unity of mind should be with the ultimate objective of restructuring the nation.
