Henry II, Duke of Bavaria
Henry II the Wrangler (951–995) inherited Bavaria at four and married Gisela of Burgundy in 972. Under Otto II he fought the emperor over a bishopric and Swabia, and a plot of 974 landed him in prison at Ingelheim. He escaped in 976 and raised Bavaria in revolt, but Otto II took Regensburg, deposed him and carved Carinthia from Bavaria.
Freed in 983, he abducted the infant Otto III and had himself proclaimed king, but submitted in 985. He recovered Bavaria and later Carinthia, dying on 28 August 995; his son became Emperor Henry II.
