Anna of Nassau-Dillenburg (1541–1616)

Anna of Nassau-Dillenburg (21 September 1541 in Dillenburg – 12 February 1616 in Weilburg) was a countesses of the House of Nassau. She married her cousin Albert, Count of Nassau-Weilburg and settled in Schloss Weilburg, where he ruled the district of Weilburg.

Life
Anna was a daughter of Count William "the Rich" of Nassau-Dillenburg and his second wife, Countess Juliana of Stolberg. She was the seventh child in their marriage, the fourth daughter. The eldest was William I of Orange (1533–1584), known as William the Silent. She had the same name as her aunt Anna of Nassau-Siegen (1440/41–1514), who had died twenty seven years before she was born.

She married Count Albert, Count of Nassau-Weilburg on 16 June 1559 in the Castle of Dillenburg. On that day in Dillenburg two other marriages in the House of Orange took place: Johann VI, Count of Nassau-Dillenburg married Elisabeth of Leuchtenberg, and Elisabeth of Nassau-Dillenburg married Conrad, Count of Solms-Braunfels.

Over the years their house inherited part of the county of Nassau-Weilburg. After his fathers dead in 1561 Albert gained part of territory and his father's debts: Weilburg, Gleiberg, Cleen, labor and Burgschwalbach.

In 1574 he inherited another part of Nassau-Saarbrücken after the death of Count John III. In 1574 a new castle was built in Ottweiler, which became their residence.
