Following his coronation, a rift developed between Otto II and his mother, the Dowager Empress Adelaide of Italy. From the death of Otto the Great until Easter 974, Adelaide accompanied the Emperor at all times, traveling throughout the Empire with him. However, Otto II's mother and his wife Theophanu each mistrusted the influence the other held over the Emperor, causing friction within the Imperial household. A final meeting between Otto II and Adelaide was arranged shortly before Pentecost in 978, but a peaceful outcome was not achieved, forcing Adelaide to retire to Burgundy and to the protection of her brother King Conrad of Burgundy.
