Final answer:
Religious syncretism is the amalgamation of different religious beliefs and traditions, forming new practices and expressions of faith.
Step-by-step explanation:
Religious syncretism refers to the blending of religious traditions. It is a process where elements from different religious systems are combined, leading to the creation of new religious forms. With the Africanization of Christianity and Islam during the medieval period, this blending can be observed in the way traditional African beliefs were incorporated into these religions, resulting in a unique expression of faith that included both African and Christian or Islamic elements. In contrast, religious syncretism is not the rejection of religious beliefs, the establishment of entirely new religious practices, nor the preservation of religious purity, but rather a merging or assimilation of two or more religious traditions.
