After the early death of her father in 1326, Agnes and her older sister
Katharina (later by marriage Lady of Coucy) were placed under the guardianship of their paternal uncles,
Frederick the Fair and
Albert II. On 1 June 1338 Agnes married with
Bolko II the Small, Duke of
Świdnica, who wanted with this union to enhance his international position against the
House of Luxembourg, direct competitors of the Habsburgs. The marriage apparently was childless, although some sources stated that they had two children: a daughter, Elisabeth (d. 1407) and a son, Bolko, who, according to old Silesian legend, died at only nine years old, accidentally killed by the court jester Jakob Thau, when he threw a stone to him during a game. After the death of her husband in 1368, and according to his will, Agnes received
Świdnica,
Jawor and
Lwówek as her
dower. Agnes died on 2 February 1392 in Świdnica and was buried in the Franciscan Princely Chapel (
Fürstenkapelle) of the
Grüssau Abbey. According to the treaty of 1353 between Bolko II and the
Emperor Charles IV, on her death the duchies were incorporated into the
lands of Bohemia by
Wenceslaus, King of the Romans. Under the rule of the Abbot Benedict II Seidel (1735–1747) was built in the
Fürstenkapelle a sculpture of white marble from Agnes, which is still there. ==References==
