Soon after Mieszko had concluded peace with the Empire, he was deposed by Bezprym. When Mieszko had assumed the Polish throne in 1025 he exiled his brother, who had fled to the Kievan Rus, east of Poland. Bezprym, with approval of Conrad, persuaded the Kevian Grand Price Yaroslav I the Wise to invade Poland and install Bezprym as sovereign. The Kievan invasion was a success. Mieszko fled to Bohemia where he was imprisoned and castrated by Duke Oldrich in retribution for Mieszko's father Bolesław's blinding of Duke Boleslaus III, Oldrich's brother, thirty years earlier. Shortly after taking power, Bezprym sent the Polish regalia to Conrad, officially renouncing the sensible title ""king"" in favor of the traditional title ""duke"" and accepting the overlordship of the Empire over Poland. The royal regalia were delivered by Mieszko II's wife, Richeza of Lotharingia.
