Baldwin I, Count of Flanders
and the couple fled to the court of Lothair II, king of Lorraine. He was Judith's cousin. Once they were safely out of her father's reach Baldwin married her. This was about 863. King Charles had his bishops excommunicate the couple. He also demanded that his nephew return Baldwin and his daughter Judith to him. At this point Baldwin and Judith fled to Rome. They asked Pope Nicholas I to intercede and legitimize their marriage. Baldwin made known his intent to join the Vikings if his marriage was not allowed. Vikings were a constant threat in northern France and Baldwin was needed to help fight them. The pope decided their marriage was valid and had the bishops withdraw their excommunication. Charles the Bald was forced to accept Baldwin as his son-in-law. The couple was married a second time, in public. Her father did not attend but sent officials to witness the marriage. He gave Baldwin the honors the pope recommended.
