Migration and inter-group relations is a historical phenomenon relating to the formation of Nigerian society that has attracted many studies. Human beings moved from one place to another in search of varieties of things such as economic opportunities and security. Through oral interviews, thesis, books and careful examination of archival materials among several other sources, this study examined the factors of migration of Igbo community into Katsina metropolis, 1903 to 2011. It seems that the migration of Igbo into Northern cities of Nigeria in general was influenced by many factors which included the establishment of the British Royal West African Frontier Force (WAFF), colonial firms, Sabon Gari and Tudun Wada settlements, missionary schools, aftermath of the Nigerian Civil War, commerceand family bonds but the case of Katsina was different. For example, there was no rail station or termina to Katsina as was the case of Nguru, Kaura Namoda, Zaria, Kano and Gusau for that matter. Similarly, unlike these cities mentioned above, Katsina had no Sabon Gari and Tudun Wada that were specially reserved for non-indigene settlers. The absence of Sabon Gari and Tudun Wada was due to non-declaration of Katsina as a township by the colonial authority during the colonial period. There was also little influence of missionary schools to attractIgbo migrantsinto Katsina as compared to most Northern cities. The research also revealed that, the loyalty/liberal disposition of Dikko to the British, and the highly cosmopolitan nature of Katsina metropolis, the tolerance and the famed hospitality of the indigenes of Katsina,National Youth Service (NYSC)Scheme, all contributed to the migration of the Igbo- migrant community into Katsina. The study further examined Igbo contributions towards the economic development of Katsina metropolis as well as why their rate of integration was basically commercial but socially slow compared to Yoruba and Nupe migrants. From this study, it is clear that the migration of Igbo community to Katsina metropolis was as a result of push and pull factors and inter-group relations.
