ABSTRACT
The problem of federalism and the associated crises of national integration in Nigeria raise serious alarm. The situation attracts growing interest and concern. The crises are very severing such that they culminate in a strong force being mounted on the federation with tendency to disintegrate the country. The works addresses this phenomenon by investigating and analysing the problem. Documentary research method is used in gathering and analysing data. So textbooks, journals, periodical publications by related government agencies formed necessary source of our data while we employed system theory for pour analytical framework. The work identifies the method of revenue allocations as the major factor responsible for the crises of national integration in the Nigerian federalism. It concludes that in face in this problem, harmonious unification or integration cannot take place, political system cannot successfully adapt to both internal and external environment such that the survival of the system is difficult. The work recommends among others that federalism is the ultimate solution to the problems of national integration, so federal character and other related approaches should be effectively enforced. Again the current unjustifiable method of revenue allocation should be reformed to reflect justice, equity and fairness.
