Duchy of Franconia
With his successes and failures in Saxony and Bavaria, Henry II's claims depended on gaining support in the Duchy of Franconia, which was a direct possession of the German kings. The Franconian nobles, led by Archbishop Willigis of Mainz (the Primate of Germany) and Conrad I, Duke of Swabia, refused to abandon Otto III. Fearing outright civil war, Henry II relinquished Otto III to the joint-regency of his mother and grandmother on 29 June 985. In return for his submission, Henry II was restored as the Duke of Bavaria, replacing Henry III who became the new Duke of Carinthia.
