The world's longest-lasting and most successful communal society, the Hutterites have a model of governance that has served them well for almost five hundred years. In the past the colony was an "ark," isolated from both the secular world and the host society. But today colonies face new challenges because of globalization and digital technologies and are losing much of their ability to exclude these influences from their lives. Based on extensive fieldwork with the Schmiedeleut branch of the Hutterites, the book includes the Conference Letters and Regulations, published for the first time in English translation, that provide invaluable insights into strategies for managing change.
