Are the Shakers the only religious group able to establish a lasting Uptopian community?

Did even the Shakers achieve that?

To the extent which Shakers achieved it, which is to say to the extent which some small set of fervent believers band together to create a community which they largely believe is following principles they all believe, well that kind of thing (whether you call it a cult or a community) happens all over the place. Consider monastic orders such as the Benedictines, which have existed for hundreds of years.

Everyone's utopia is different, but you can find small groups close enough to agreement to make it work, sometimes for much longer than Shakers.
