The Witchcraft Research Association.
In 1964 Doreen Valiente was involved in the creation of the Witchcraft Research Association. It was set up by Gerard Noel in an effort to unite Britain's Witches, no matter what tradition they came from. To this end, they produced a small publication called Pentagram which is available for download below.
