As Nigeria grew as an independent nation, the role of the Church Missionary Society (CMS) began to evolve, reflecting the needs of a burgeoning multi-ethnic society. This transformation is particularly evident in the Diocese on the Niger – the first indigenous Anglican diocese in Western Africa – a topic of debate within various factions of the Church of Nigeria, Anglican Communion. These contentions – centred on historical accuracy, heritage and primacy – mirror broader socio-political disputes concerning the Igbo people’s history and reveal postwar ethnocentric trends in Nigeria. We propose that the strategic positioning of the Diocese on the Niger was part of the CMS mission’s expansion plan into Islamic-dominated Western and Northern Nigeria. Igboland, with its geographical significance and potential as a fertile ground for the gospel, was a deliberate choice. The debates around these contested viewpoints and legacies epitomize the societal disputes over historical interpretation and its theological implications – extending beyond the events themselves and prompting reflection on the embodiment of Christ’s teachings in navigating socio-political complexities. These discussions go beyond religious or geographical disagreements – they symbolize a broader struggle to understand and interpret the past.
