The traditional religion of the Ijaw people of Nigeria's Niger Delta is shared in its broad shape across many sub-groups, among them the Kalabari, Nembe, Okrika and the western Ijaw, even where local naming and emphasis vary. A high creator is held responsible for making and for controlling the destiny of everything on earth, called Woyengi, meaning our mother, among the western Ijaw and Tamuno among the Kalabari, the difference in name sitting over a broadly common cosmology rather than a different creator altogether. Day to day religious life centers less on that distant creator than on ancestor veneration and on a wide range of bush and water spirits who must be properly propitiated for the community's wellbeing. Egbesu, a war and justice deity invoked to enforce oaths and redress wrongs, has kept a public role well beyond the purely religious, remaining a living reference point in Niger Delta public life into the twenty first century, invoked in contexts far from a shrine. Ancestor veneration and belief in these spirits persist among Ijaw communities that have not converted to Christianity, and continue today alongside widespread Christian affiliation rather than in opposition to it.
