The constitution of the Third Republic was drafted in 1989, marking the culmination of the work of a constituent assembly. General
Ibrahim Badamasi Babangida (IBB), the
military Head of State at the time, had initially pledged to end military rule by 1990. However, this timeline was later extended to 1993. In the spring of 1989, IBB lifted the ban on political activities, which had been in place since the 1983
coup. The constitutional conference established two government-created political parties: the centre-right
National Republican Convention (NRC) and the centre-left
Social Democratic Party (SDP). Both parties were mandated to have a national outlook, rather than being based on ethnic or regional affiliations.
Gubernatorial and state legislative elections were held in December 1991. The elected civilian governors and state legislators assumed office in January 1992. The presidential election, originally scheduled earlier, was postponed until 12 June 1993 due to political instability.
Moshood Kashimawo Olawale (MKO) Abiola, a wealthy
Yoruba businessman, won a decisive victory under the SDP platform, defeating
Bashir Tofa of the NRC. Abiola won in Tofa's home state in the North, the Federal Capital Territory (
Abuja), military polling units, and in over two-thirds of Nigeria's states. Despite northern dominance in the country's post-independence political landscape, Abiola's appeal was national. Years later, IBB reportedly described the annulment of the 1993 election as unfortunate, though he maintained it was the right decision at the time. He claimed to have received intelligence suggesting that Abiola's government would soon be overthrown in a military coup, which in his view made a transition to civilian rule futile. He acknowledged the irony of General
Sani Abacha's subsequent coup, but insisted that the eventual military takeover was precisely what he had hoped to avoid. The federal legislators were, however, more fortunate. After a series of delays following the 4 July 1992 legislative elections, the Third
National Assembly was finally inaugurated on 5 December 1992. The same election saw the emergence of notable political figures such as
Bola Ahmed Tinubu, then a protégé of
Abiola, elected as Senator for
Lagos West, and
Chuba Okadigbo, a philosopher and later Senate President in the
Fourth Nigerian Republic, elected as Senator for
Anambra North. Informal sources alleged that General
Babangida supported the establishment of a legislature to give the government the appearance of representative democracy, but had no intention of relinquishing executive power to an elected president. While he continued to delay the presidential election, he reportedly lobbied members of the National Assembly to recognise him as the legitimate president, offering them the continuation of their positions as an incentive. The eventual collapse of the Third Republic was seen by many as inevitable. ==Political parties==
