Henry I the Bearded
When she was three years old, Agnes was entrusted to the care of St. Hedwig of Andechs, the wife of Duke Henry I the Bearded of Silesia. Hedwig placed her to be educated by a community of Cistercian nuns in a monastery which she herself had founded in Trzebnica. Upon her return to Prague, Agnes was entrusted to a priory of Premonstratensian Canonesses to continue her education.
