A spiritualist church is a church affiliated with the informal spiritualist movement which began in the United States in the 1840s. Spiritualist churches are now found around the world, but are most common in English-speaking countries, while in Latin America, Central America, Caribbean and Sub-Saharan Africa, where a form of spiritualism called spiritism is more popular, meetings are held in spiritist centres, most of which are non-profit organizations rather than ecclesiastical bodies.
The origin of mediumship is usually linked to the seances conducted by the Fox sisters at Hydesville, Arcadia, New York, in 1848, but some believers date the unofficial beginning of modern American Spiritualism to the Shakers and similar religious groups. By 1853 the movement had reached San Francisco and London, and by 1860 was worldwide. The Fox family remained very active in Spiritualism for many years. Other notable Spiritualists of that era were Mercy Cadwallader, who became a sort of missionary for the movement, and Emma Hardinge Britten, who wrote for the first Spiritualist newspaper in Britain, The Yorkshire Spiritual Telegraph.
By the 1870s there were numerous Spiritualist societies and churches throughout the US and Britain, but there was little in the way of national organization of mediums in Britain or the United States although some regions of Britain had organized Federations that might have up to thirty circles of similar beliefs. In 1891 the National Federation of Spiritualists (NFS) came into existence and grew quite large before its name change to the Spiritualists' National Union (SNU) in 1902.
British spiritualists of this time were often adherents of the temperance and anti-capital punishment lobbies, often held radical political views and were frequently vegetarians. Some were active in the advocacy of women's rights and female suffrage, and a minority espoused Free Love: the popular perception of Spiritualists was often of radicals in the Victorian period.
