Post colonial Ibo religion
However, prior to the post colonial period, they began converting to Christianity due to the missionaries presence in Nigeria. This caused many of them to go from polytheism to monotheism. Although this was a huge impact on the Ibo people, many of them still remained indigenous to their religion. For example, Ibo people still believed in the governments law of retributive justice being controlled by Ofo and Ogu. Which determined ones fate in which people were either guilty or not. This heavily depended on their fortune of misfortune that was upon them. (Ibo people new world encyclopedia)
