Болеслав II
After initially siding with Henry II against Otto II during Henry's failed revolt in 977, Boleslaus II swore loyalty to Otto II. When Otto II died suddenly in 983 and was succeeded by the three-year old Otto III, Boleslaus II again supported Henry II in his bid for the German throne. As in 977, Henry's bid failed, and Boleslaus II swore loyalty to Otto III.
