The term 'Shakers et al' refers to a group of religious SECTS, including the Shakers, who were founded in the 18th century. These SECTS were characterized by their communal lifestyle, celibacy, and spiritual practices such as ecstatic dancing and singing. They were also known for their simple and plain dress, furniture, and architecture. The Shakers were one of the most successful of these SECTS, with members in the United States, Canada, and England.
