Causes for Federalism
The demand for the creation of newer states in Nigeria tends to emanate from sub-state groups, often ethnic- or tribal-interest groups, which accuse the current larger state governments of subverting or ignoring the interests and necessities of the more local regions.
Effects of Federalism
A much-criticized effect of the current type of federalism, of 36 states from previous pre civil war 3 regions is the creation of a political subclass of state bureaucracies, often headed by governors who are accused of and sometimes successfully prosecuted for, monetary corruption.
Furthermore, one of the outstanding peculiarities of Nigerian politics emanates from the promulgation of sharia law in the northern states, which is only applicable to Muslim residents, while Nigerian states outside the “sharia zone” operate their legal systems by common and customary law.
