Wicca is a modern pagan religion influenced by ancient Celtic traditions and Egyptian/Greco-Roman goddesses. It focuses on nature and celebrates seasonal holidays and rituals. Key beliefs include practicing magic/witchcraft, following the Wiccan Rede of "harming none", and worshipping both a Mother Goddess and Horned God representing nature. Major holidays include Ostara/Easter in spring, Samhain/Halloween in fall, and Yule in winter. Rituals may involve elements, deities, and binding ceremonies like handfasting.
