Wicca is another term for the Wiccan religion, one of the main Pagan faiths. It is Earth-centered and worships the gods and the goddesses of nature. There are many branches of Wicca — and just as many claims as to where it originated. The truth is that while it is a very old religion, Wicca today is more neo-Paganism than anything. You can practice witchcraft without being Wiccan.
