In 1370 and 1374 John I, Duke of Lorraine, had twice to re-take possession of Saint-Hippolyte, which he then passed to his father-in-law Eberhard II, Count of Württemberg, who two years later resold it, in 1393, to the bishop of Strasbourg. Eberhard III, Count of Württemberg then took control of Saint-Hippolyte, before returning it to Friedrich von Blankenheim, bishop of Strasbourg. In 1430, Anton von Hattstatt of Viller received a grant for life from Charles II, Duke of Lorraine, of the town of Saint-Hippolyte and the castle of Haut-Koenigsbourg, in return for which Antoine made Charles his heir.
