In page Otto III, Holy Roman Emperor:
"Otto III's cousin Henry II had been deposed as Duke of Bavaria by Otto II in 976 following his failed rebellion and imprisoned within the Bishopric of Utrecht. Following Otto II's death, Henry was released from prison. As Otto III's nearest male Ottonian relative, Henry II claimed the regency over his infant cousin.[1] Archbishop of Cologne Warin granted Henry II the regency without substantial opposition. Only Otto III's mother Theophanu objected, along with his grandmother, the Dowager Empress Adelaide of Italy, and his aunt, Abbess Matilda of Quedlinburg. Adelaide and Matilda, however, were both in Italy and unable to press their objections.[citation needed]
