History
The National Spiritual Alliance of the U.S.A. was formed in 1913 by the Rev. G. Tabor Thompson, previously a medium with the New England Spiritualist Camp Meeting Association, and an advocate of belief in reincarnation, an opinion at variance with the National Spiritualist Association of Churches (NSAC).
