Paganism is a broad group of religions, including modern pagan religions, indigenous religions and historical polytheistic religions. Modern knowledge of old pagan religions comes from several sources, including: anthropological field research records, the evidence of archaeological artifacts, and the historical accounts of ancient writers regarding cultures known to the classical world. Paganism is often taken to exclude monotheism, and to express a worldview that is pantheistic, polytheistic, and/or animistic. In a wider sense, paganism has also been understood to include any non-Abrahamic, folk, or ethnic religion.
Contemporary or modern paganism, also known as neopaganism, is a group of new religious movements influenced by, or claiming to be derived from, the various historical pagan beliefs of pre-modern Europe.
