Frederick II (German: Friedrich II.; 25 April 1211 – 15 June 1246), known as Frederick the Quarrelsome (Friedrich der Streitbare), was Duke of Austria and Styria from 1230 until his death. He was the fifth and last Austrian duke from the House of Babenberg, since the former margraviate was elevated to a duchy by the 1156 Privilegium Minus.[1] He was killed in the Battle of the Leitha River, leaving no male heirs.


Born in Wiener Neustadt, Frederick was the second surviving son of the Babenberg duke Leopold VI of Austria and Theodora Angelina, a Byzantine princess. The death of his elder brother Henry in 1228 made him the only heir to the Austrian and Styrian duchies.

His first wife was Byzantine princess Sophia Laskarina, probably a daughter of Theodore I Laskaris and his first wife Anna Komnene Angelina, who died in 1222. Frederick secondly married Agnes of Merania in 1229, a member of the noble House of Andechs whose dowry included large possessions in Carniola and the Windic March. From 1232 Frederick called himself Dominus Carniolae ("Lord of Carniola"), however, the couple divorced due to childlessness in 1243.
