This paper extends the scope of earlier studies of Karl Barth's relationship with Charlotte von Kirschbaum by exploring his marriage to Nelly Barth and the deterioration in their relationship in the 1920s. It traces the development and character of Barth's relationship with Kirschbaum, and the Notgemeinschaft (emergency community) they formed with Nelly. The paper makes use of Nelly Barth's unpublished letters to her family in which she accounts for her reluctance to divorce her husband in the early 1930s. The second half of the paper explores the impact of Barth's relationship with Kirschbaum on others and goes on to suggest ways in which this had consequences for his theology, particularly in his thinking in Church Dogmatics III/4 about the relation between man and woman.
