A shaker can refer to different things, but based on the search results, it can refer to the United Society of Believers in Christs Second Appearing, commonly known as the Shakers. The Shakers are a millenarian restorationist Christian sect founded in England in the mid-1700s and organized in the United States in the 1780s. They practice a celibate and communal utopian lifestyle, pacifism, uniform charismatic worship, and their model of equality of the sexes, which they institutionalized in their society in the 1780s. They are also known for their simple living, architecture, technological innovation, music, and furniture. The Shakers believed in opportunities for intellectual and artistic development within the Society. Simplicity in dress, speech, and manner were encouraged, as was living in rural colonies away from the corrupting influences of the cities. Dancing was a key expression of Shaker spirituality, and was often described as a spiritual and physical means through which the Believers could shake off their sins.
