Editing House of Babenberg (section)

===Extinction===
[[Frederick II of Austria|Frederick II]], [[Leopold VI, Duke of Austria|Leopold VI's]] son by [[Theodora Angelina (wife of Leopold VI of Austria)|Theodora Angelina]], succeeded his father as duke upon the elder man's death in 1230. Frederick II soon earned the epithet "the Quarrelsome" from his ongoing disputes with the kings of [[Kingdom of Hungary|Hungary]] and [[Kingdom of Bohemia|Bohemia]] and with [[Frederick II, Holy Roman Emperor|Holy Roman Emperor Frederick II]]. Duke Frederick deprived his mother and sisters of their possessions, was hated by his subjects on account of his oppressive rule, and, in 1236, was placed under the imperial ban and driven from Austria.<ref name="EB1911"/> However, he was later restored to his duchy when Emperor Frederick II was excommunicated. Subsequently, Duke Frederick II treated with Emperor Frederick II in vain to make Austria a kingdom.

The male line of the Babenbergs became extinct in 1246, when Frederick II was killed in battle (the [[House of Henneberg|Henneberg branch]] of the Franconian Babenbergs lived on until 1583 when its lands were divided among the two branches of the [[Wettin Dynasty|Wettin family]]).

Frederick's heir general was [[Gertrude of Austria]], the only child of his late elder brother, [[Henry of Austria]] by that man's wife, [[Agnes of Thuringia]]. However, neither her husbands nor her son succeeded in settling the Babenberg inheritance under their power. Gertrude's only surviving child, [[Agnes of Baden, Duchess of Carinthia|Agnes of Baden]], tried to reclaim at least part of her inheritance through her third husband [[Ulrich II of Heunburg]], but was unsuccessful.

After some years of struggle known as the {{ill|Austrian Interregnum|de|Österreichisches Interregnum|uk|Австрійська війна (1246—1278)}} or War of the Babenberg Succession (1246–1256/78/82), the Duchies of Austria and Styria fell to [[Ottokar II of Bohemia]], and subsequently to [[Rudolph I of Germany|Rudolph I]] of [[Habsburg]], whose descendants were to rule Austria until 1918.
