As southern Nigeria was not as united as the north, it was disadvantaged in the power struggle. During his tenure, killing of Easterners in the north continued; several retaliatory actions took place, eventually resulting in the Biafran war.
In July 1966 Northern officers staged a counter-coup to revenge on the easterners for the targeting their own political leaders in the first coup; Lt. Nigeria, which gained independence from the United Kingdom in 1960, had at that time a population of 60 million people, made up of more than 300 differing ethnic and cultural groups.

Intended for better administration due to the close proximity of these protectorates, the change did not account for the great difference in the cultures and religions of the peoples in each area.

A statement issued by the hospital chain revealed their family had done an 'excellent job' caring for them and they were in good health.
The pair made the 4,600-mile (7,500km) journey to a specialist hospital in Bangalore for the marathon operation that involved 22 specialists.
Medics now claim the twins are ready to live 'independent lives' - despite spending the first six months of life attached to each other.
Conjoined twins, who arise from a single embryo, strike just one in every 100,000 births, according to medical literature.
Survival rates are very low, about half of them may die before birth and another 25 per cent soon after. Unlike normal twins, they fail to separate in the womb and the pair end up joined together at some parts of their body.
