Henry, Prince of Nassau-Dillenburg

He studied at Herborn Academy, which could enjoy an upswing during his rule, and in France. After completing his studies, he served in the Dutch army, where he reached the rank of commander. When his grandfather, Louis Henry, Prince of Nassau-Dillenburg, died in 1662, he inherited the county, because his father had already died. When his uncle Adolph died without a male heir in 1676, he inherited Nassau-Schaumburg as well.

His reign is regarded as competent but unspectacular. He tried unsuccessfully to claim the inheritance of his father-in-law, George III of Brieg. After his death, he was succeeded by his oldest son William II, and after William II died without a son, by his younger son Christian.

He married in 1663 with Dorothea Elizabeth, the daughter of Duke George III of Brieg.
