Most Anarchists considered mutually linked communities of independent producers as the nuclei to their vision of a society without governments. In the United States, the large experimental field of social Utopias, anarchist circles appeared simultaneously with the debut of socialism during the first half of the nineteenth century. However there were only a few attempts to realize their vision of a future society. During the nineteenth century only a handful of Utopian communities were established by anarchists. Most survived for short periods only and none formed communal entities, because their founders and members were close to the individualistic trends of anarchism.
