The historic and geographic ethnic minority Delta region of Nigeria, which may be called the Nigerian Delta region or the Niger Delta region, has been in existence from time immemorial, as other primordial ethnic nationality areas and regions, which were in existence centuries before the birth of modern Nigeria. In the early times, the people of the Niger Delta region established foreign relations between and among themselves, as people of immediate neigbouring primordial areas or tribes. They also established long-distance foreign relations with distant tribes that became parts and parcels of modern Nigeria. The Niger Delta region, known as the Southern Minorities area of Nigeria as well as the South-South geo-political zone of Nigeria, is the primordial and true Delta region of Nigeria. The region occupies a very strategic geographic location between Nigeria and the rest of the world. For example, with regard to trade, politics and foreign relations, the Nigerian Delta region has been strategic throughout history, ranging, for instance, from the era of the Atlantic trade to the ongoing era of petroleum resources development in Nigeria. Ancient Niger Delta represents a distinct area of primordial African civilisation. So, the existence of the oil-rich ethnic minority Delta region predates petroleum resources development operations in Nigeria, which operations commenced with the discovery of commercial quantities of crude oil in the oil producing communities of the region in the late 1950s. Thereafter, when petroleum resources were discovered in the communities of neighbouring States of the true Niger Delta region, namely Abia and Imo States of the Igbo major ethnic group, and Ondo State of the Yoruba major tribe, these three oil producing States became integrated into the framework of the true Delta region, by virtue of the Niger-Delta Development Commission (Establishment, Etc.) (NDDC) Act, 2000 (as NDDC States). This Act made the Niger Delta region to be synonymous with petroleum resources development. It is significant to highlight that ceaseless agitation of citizens and citizen-groups of the oil-rich ethnic minority Delta region helped to persuade the Federal Government (FG) to take appropriate steps to address the age-long problems of neglect, marginalisation and deprivation of the region. The agitation of interest groups of the Niger Delta region stems from the fact that whereas the region has been the goldmine of Nigeria, it is experiencing paradoxes associated with unsustainable petroleum resources development operations. These paradoxes made the Delta region to become endangered and crises-ridden as well as generated the region’s historic ‘resource control’ movement, which advocates that the region deserve to have maximum benefits from petroleum development operations in its oil-rich communities. Consequently, through the National Assembly, the FG led by President Olusegun Obasanjo had to take key steps, one of which was the enactment of the NDDC Act that formally repealed the Oil Mineral Producing Areas Development Commission Decree (OMPADEC) Decree, No. 23 of 1992, and dissolved the Commission established thereby. Therefore, the aim of this study is to demonstrate that the true Niger Delta region is distinct and thus improperly categorised with other oil producing States and areas in the context and framework of the NDDC Act. This is a food for thought that warrants serious consideration, analysis and evaluation. Consequently, the study recommends that there is a need for the FG, through the National Assembly, to further amend the NDDC Act, to make its provisions align more with petroleum resources development and that meanwhile the erroneous manner of referring to or considering the Niger Delta region as the ‘Nigerian Niger Delta region’ or the ‘Niger Delta region of Nigeria’, should, at least, be corrected in the parlance of the knowledge industry, by stakeholders of the industry, particularly scholars, beginning with Nigerian scholars .
