In the course of 1628 he discovered an affair of his wife, Kirsten Munk, with one of his German officers. When he put her away she tried to cover up her own disgrace by suggesting an affair between one of her fired maids and the king. In January 1630 they separated completely. Kirsten went away to Jutland. Meanwhile, Christian openly declared Vibeke as his mistress. She gave birth to a large family. Vibeke's children were of course the natural enemies of the children of Kirsten Munk. The anger of the two families influenced the future history of Denmark.
