As Brysing mentioned, the Anglo-Saxons were Germanic tribes that first invaded Britain in the 5th century AD and continued to rule Britain until the invasion of the Normans under William the Conqueror in 1066. The Anglo-Saxon words " Wicce " (a female Witch) and " Wicca " (a male Witch) are the root of the modern Wicca as a religion.
There are two forms of Dianic Witchcraft (not Wicca). The first was founded by Z. Budhapest and is strictly for women only and for the worship only of the Goddess. There is no male deity in her form of Wicca. The other group are the McFarland Dianics who do permit men into their circles and who worship the God as a consort, but lesser than the Goddess.
Wicca on the other hand is based on gender polarity/equality. Both the God and the Goddess are essential to Wicca as the religion is basically a fertility cult..
