Spring – Coup of Kaiserswerth: The 11-year-old King Henry IV is abducted, as a result of a conspiracy of German nobles led by Anno II, archbishop of Cologne. Henry's education and training is supervised by Anno, who acts as his regent and is called his magister (his "master" or "teacher"). Empress Agnes of Poitou (Henry's mother) resigns the throne, and Anno with the archbishops Siegfried I and Adalbert of Hamburg takes her place.[1]
