Brüderbewegung
The Open Brethren form independent, autonomous assemblies and the name "Open" is given to them to distinguish them from "Exclusive Brethren", with whom they share historic roots. The division of the Plymouth Brethren into the Open Brethren and the Exclusive Brethren took place in 1848. Open Brethren are also commonly known as "Plymouth Brethren", especially in North America. Many Open Brethren outside North America, however, are unwilling to use the "Plymouth Brethren" designation because it is associated with the Exclusive Brethren, particularly the Plymouth Brethren Christian Church, which has often been accused of being a cult and has attracted a considerable degree of unfavourable publicity in the media.
