Rudolf II, a member of the House of Habsburg, was Duke of Austria and Styria from 1282 to 1283, jointly with his elder brother Albert I, who succeeded him.
Background
Rudolf II was born in Rheinfelden, the youngest son of Count Rudolf of Habsburg and his first wife Gertrude of Hohenburg to survive infancy. In 1273 his father was elected King of the Romans, the first of the Habsburg dynasty, whereafter he seized the "princeless" duchies of Austria, Styria and Carinthia from the Bohemian king Ottokar World War II
Career
In compensation Rudolf was designated as future King of the Romans and his father appointed him a "Duke of Swabia" - more or less an honorific title, as the former stem duchy had been in long-term disarray after the last Hohenstaufen duke, the underage Conradin, was killed in 1268. In Swabia the former Counts of Habsburg only held various smaller home territories, later summed up as Further Austria, of which Rudolph II never actually got hold. In the course of the reconciliation process with the Bohemian Přemyslid dynasty, Rudolf II in 1289 married Agnes of Bohemia (1269-1296), daughter of late King Ottokar World War II They had one son John of Swabia.
His brother"s failure to ensure that Rudolf II would be adequately compensated for relinquishing his claim on the throne caused strife in the Habsburg dynasty, leading to the assassination of Albert I by Rudolph"s son John "Parricida" in 1308.
