Karl was the only surviving child of the Duke Julius Siegmund of Württemberg-Juliusburg (1653–1684) from his marriage to Anna Sophia (1647–1726), the daughter of the Duke Adolf Frederick I of Mecklenburg-Schwerin.
He became Duke of Württemberg-Juliusburg when his father died in 1684, although he stood under guardianship until he came of age in 1704. The marriage remained childless. Charles ruled arbitrarily and wastefully.
In 1740, his councilors therefore turned to emperor Joseph I, who ruled against the Duke.
In 1742, Karl asked his country"s captain for a new wig, however, it was not granted due to an empty treasury. He then sold off the Lordship of Goschütz and the city of Twardogóra, the latter to Count henry of Reichenbach-Goschütz (1705–1775).
Charles died in 1745.
