The people of Iyankpo (Tombia and Finnema) in the present RiversState of Nigeria where one people in pre-colonial times before Tombia moved to the western Rio-Real area and settled prior to the emergence of Kalabari in the Rio Real area. But the people of Kalabari claim to participate in the trans-Atlantic trade of salt salted fish and later slaves when neither Bonny nor Kalabari was in existence in the 15^th century. The Kalabari claim to have participated in the trans-Atlantic trade with the Portuguese is problem statement to this study. The reaearch method is qualitative gathering materials from primary and secondary sources.  Theory is post-colonial theory of correcting historical fallacies in African history. From the findings of the study the Iyankpo people settled the Bonny people at Orupiri while the Kalabari were developed by the magnanimity of the Tombia people. The Portuguese records of the period mentioned only the deity Simingi, of the Iyankpo (Tombia and Finnema) people who they traded with. Then there was no Ikuba of the Bonny people or Akaso of the Kalabari people. Thus, the need to clarify historical fallacies in post-colonial history. 

Key words: Tombia, Bonny and Kalabari Niger Delta.
