Grand Duchy

n. territory governed by a grand duke or duchess

A grand duchy is a territory whose head of state is a Grand Duke or Grand Duchess.The only grand duchy in existence today is Luxembourg. It has been a grand duchy since 1815 when the Netherlands became an independent kingdom and Luxembourg was handed over to the King of the Netherlands, William I. Luxembourg remained a Dutch dominion until 1890 when William III, King of the Netherlands and Grand Duke of Luxembourg, died without leaving a male heir, so that in the Netherlands he was succeeded by a female and, in the Luxembourgish Grand Duchy, by a distant male cousin, Duke Adolf of Nassau who became HRH Grand Duke Adolphe—an arrangement necessitated by  Salic law being applicable to Luxembourg but not to the Netherlands. The present Grand Duke of Luxembourg is Henri.
