Political and social idea of the mid-19th century.
Adapted from such reformers as Robert Owen and Charles Fourier , utopian socialism drew from early communist and socialist ideas. Advocates included Louis Blanc , noted for his theory of worker-controlled "social workshops," and John Humphrey Noyes , founder of the Oneida Community in the U.S. Utopian settlements were also attempted by religious groups such as the Mennonite s, Shaker s, and Mormon s.
