The answer is they involve elaborate initiation rituals.
This is not a general feature of African religions. While some religions, like Islam, require pilgrimages to sites on other continents (e.g., Mecca), African traditional religions typically focus on local sacred sites and do not mandate pilgrimages to other continents.
African religions are often characterized by syncretism, where elements of different religious traditions are blended. This is evident in how African traditional beliefs have integrated aspects of Christianity and Islam in various regions.
African religions are generally pluralistic, with a wide variety of beliefs and practices that can coexist. This pluralism is seen in the diversity of deities, spirits, and rituals across different ethnic groups and regions.
Elaborate initiation rituals are a common feature of many African religions. These rituals often mark important life stages, such as the transition from childhood to adulthood, and involve complex ceremonies that are deeply rooted in the community's cultural and spiritual life.
