Henry Casimir II of Nassau-Dietz was born in
The Hague, the eldest son of
Willem Frederik of Nassau-Dietz and
Countess Albertine Agnes of Nassau, daughter of
Frederick Henry, Prince of Orange, stadtholder of Holland, Zeeland, Utrecht, Guelders, and Overijssel. When his father, a member of the branch of
Nassau-Dietz, died on October 31, 1664, he was made stadtholder of Friesland and Groningen (under guardianship of his mother as he was then seven years old). In 1675, Friesland voted to make its stadtholdership hereditary in the house of
Nassau-Dietz. Hendrik Casimir II was therefore the first Friesian stadtholder. In 1683, he married his cousin
Henriëtte Amalia of Anhalt-Dessau, daughter of
John George II, Prince of Anhalt-Dessau. Hendrik Casimir died in
Leeuwarden, and was succeeded as stadtholder by his son
Johan Willem Friso of Orange-Nassau. == Issue ==
