Rudolf II of Austria

Rudolf II of Habsburg (c. 1270–1290), called the Debonair, was the youngest son of King Rudolf I of Germany. In 1282 his father enfeoffed him and his elder brother Albert with Austria and Styria jointly, but under the Treaty of Rheinfelden in 1283 Rudolf surrendered his share to Albert, receiving instead the honorific title Duke of Swabia.

In 1289 he married Agnes, daughter of King Ottokar II of Bohemia. He died in May 1290, aged twenty; his son John Parricida later murdered Albert in 1308.
