Countess Henriette Catherine of Nassau

The Thirty Years War had left Germany in ruins but the Netherlands under the reign of Henriette's father, Frederick Henry, had made great progress since the assassination of William the Silent. Her father wanted to make peace with Germany and so married some of his daughters off to German nobles.

Her mother, continuing this policy had Henriette married to John George II, Prince of Anhalt-Dessau in Groningen on 9 September 1659. Henriette's consent cannot have been taken for granted: she was a woman of spirit and independence, who had already refused to marry a cousin whom she disliked,[2] and for a time considered marrying her brother-in-law Charles II of England. Judging by his letters Charles may have been genuinely in love with her, but later said that he was happy about her marriage, and believed that Henriette and John had married for love.[3]

Henriette and John George were a great influence over the German court at agriculture, construction of ports, levees, architecture and painting. In 1660, John George gave his wife the town of Nischwitz where she built houses and a cemetery, made glass and brought it to fruition.[4]

John George died in Berlin 1693. Their son, Leopold was still only a minor, so Henriette resumed regency for his son until he came of age, and resigned from regency in 1698.[5] She was first regent during his minority; when he became of age, however, she continued as regent due to his absence from the Principality, and thus did not resign her regency until 1698.

During her regency, she founded a refuge home for children and women and instituted regulations for lawyers and a system for the care of orphans.[6]

Henriette died in 1708.
