Wicca was born in 1950’s and one of it’s biggest influencers was Gerald Gardner and it is quite wide spread neo-pagan religion. Main things in wicca are honoring the nature, witchcraft and sabbaths. Even if the witchcraft is a part of wicca, not all wiccans are witches.
There are two main branches of wicca, the more traditional way of Wicca that has quite strict rules about everything and then the eclectic wicca that gives the practitioner more room to modify his/her habbits of practicing the religion.
Wicca has gotten some influences from Celtic and Germanic cultures and the wiccan sabbaths are based on the sabbaths of these cultures; Samhain (new year in october), Yule, Imbolc, Ostara, Beltaine, Litha, Lughnasadh and Mabon.
The traditional wicca is dualistic religion so there is one god and one goddess. The eclectic wicca is polytheistic religion and there’s many different gods and goddesses. One of the best known features of (traditional) wicca is the coven – a circle of practitioners that usually spend the sabbaths together and have their own traditions and ways od practicing wicca. If the (eclectic) practitioner doesn’t belong to any coven, he/she is called solitary practitioner.
Wiccans perform many kinds of rituals especially during sabbaths, but also off sabbaths. Many wiccans have their own altar where can be found a candle, an athame (ritual knife that symbolizes the god), a chalice (that symbolizes the goddess) and a pentacle (that symbolizes the elements of fire, earth, air and water).
Wicca is one of the official religions of the USA.
