Boleslaus II
When Boleslaus II allied with the Lutici and entered into war with Mieszko I of Poland in 990, Margrave Eckard led the united German-Polish forces against Bohemia. Margrave Eckard had to restore Thiadric, Bishop of Prague to his see after his expulsion by Boleslaus II of Bohemia. In 996 he accompanied Otto III on his campaign to Rome, where the king was crowned Holy Roman Emperor by Pope Gregory V. Two years later, Eckard's forces helped to suppress the revolt of Crescentius the Younger in 998 by storming Castel Sant'Angelo. Eckard was high in the favour of Otto III, who rewarded him handsomely by converting many of his benefices (fiefs) into "proprietas" (allods).
