Beginning with trans-Atlantic slavery, which forced hundreds of thousands of people into what is presently the United States, religion among African Americans consistently featured a complex of efforts toward innovation, preservation, and agential intervention rooted in efforts toward survival against structures of racial domination. Social factors including slavery, black responses to a range of political conflicts, influences of immigration, and the varieties of genealogies that have constituted religious formations among African Americans contributed to the creation of formal Christian denominations, intentional communities of Orisha, and transnational movements of Islam. Also important are the insurgent challenges that African Americans have proffered as a rejoinder to social oppression. But this progressive tendency has been paralleled by sharply conservative religious formations that check any easy generalization of African American religions as being predisposed toward social justice movements. Also important are social sources of autonomous church formation, the role of Black Nationalism, anticolonial forms of religion, and Yoruba revivalism of the mid-20th century.
