From 976 until 1246, the Margraviate of Austria and its successor, the Duchy of Austria, was ruled by the House of Babenberg. At that time, those states were part of the Holy Roman Empire. From 1246 until 1918, the duchy and its successor, the Archduchy of Austria, was ruled by the House of Habsburg. Following the defeat of Austria-Hungary in World War I, the titles were abolished or fell into abeyance with the erection of the modern Republic of Austria.
