Anna von Sachsen (1544–1577)
The only child of of Maurice (1521–1553), elector of Saxony and Agnes of Hesse (1527–1555), Anna was born in Dresden in 1544. Following the death of her parents, she was placed under the guardianship of her grandfather Philip of Hesse and her uncle Augustus of Saxony. Despite being raised a Lutheran, the husband finally selected for her—William of Orange (1533–1584)—was a practising Catholic. Negotiations for the match were protracted and Philip II, in particular, raised objections. The ceremony was conducted on 12 August 1561 but, despite the birth of five children, the marriage was not happy. William found Anna difficult and demanding, and their relationship deteriorated when William left to fight the duke of Alva, leaving Anna with his family in Dillenburg.
In October 1568, Anna departed for Cologne with her court. She did not have sufficient funds to sustain independence and, when she found herself in debt, William and his family refused to help. William asked his wife repeatedly to return to Dillenburg, but she refused. Following confirmation in 1571 of her pregnancy with a child that could not be William’s, her legal advisor (and ultimately the father of the painter and diplomat Paul Peter Rubens) Jan Rubens (1530–1587) was arrested and William arranged the annulment of the marriage. The following year Anna was sent to Beilstein Castle, where she was kept in solitary confinement that was relieved only for visits from a Lutheran preacher. In 1575 Anna was transferred to Dresden, where she was forced to live in a windowless room and her food was delivered through a panel in the door. Anna suffered both mentally and physically during her imprisonment. She died in 1577 at the age of just thirty-two and was buried in Meissen.
