Modern paganism, also known as contemporary paganism and neopaganism, is a type of religion or family of religions influenced by the various historical pre-Christian beliefs of pre-modern peoples in Europe and adjacent areas of North Africa and the Near East. Although they share similarities, contemporary pagan movements are diverse and as a result, they do not share a single set of beliefs, practices, or texts. Scholars of religion often characterise these traditions as new religious movements. Some academics who study the phenomenon treat it as a movement that is divided into different religions while others characterize it as a single religion of which different pagan faiths are denominations.

Prehistoric religion is the religious practice of prehistoric cultures. Prehistory, the period before written records, makes up the bulk of human experience; over 99% of human experience occurred during the Paleolithic period alone. Prehistoric cultures spanned the globe and existed for over two and a half million years; their religious practices were many and varied, and the study of them is difficult due to the lack of written records describing the details of their faiths.
