Silver Pfennigs and Small Silver Coins of Europe in the Middle Ages

Rudolph II, son of King Rudolph I, Duke 1282-1283
Jointly with his Brother, Albrecht I
Duke Rudolph II of Austria, titular Duke of Swabia (1270–May 10, 1290) was the younger son of Rudolph of Habsburg, from
1273 King of the Romans, and Gertrude of Hohenburg.
In December 1282 he became Duke of Austria and Styria jointly with his brother Albert I. However, in the Treaty of Rheinfelden
(June 1, 1283) he had to relinquish his share. In 1289 he married Agnes of Bohemia (1269-96), daughter of Otakar II of Bohemia
and had one son John. He died in the same year his son was born, at the age of 20.
His brother's failure to ensure that Rudolf would be adequately compensated for relinquishing his claime on the throne caused
strife in the Habsburg family, leading to the assassination of Albert by Rudolph's son John Parricida in 1308.
His father King Rudolf also made him Duke of Swabia, a province in long-term disarray where the last duke, the underage
Conradin, had been killed in 1268 and where the Habsburgs themselves were the most powerful provincial lords.
Rudolph III, son of Albert I, Duke 1298-1307
Jointly with his Father, Albrecht I
Rudolf I of Habsburg (Czech: Rudolf I. Habsburský; 1281 – 3/4 July 1307,
Horadovice in Bohemia) was King of Bohemia (1306–1307), Duke of Austria (as
Rudolph III), and titular King of Poland 1306–1307. He was the son of Albert I of
Germany and Elisabeth of Tirol.
On May 25, 1300, he married Blanche, daughter of Philip III of France by his second
wife Maria of Brabant. Their only daughter died young, and Blanche herself
died in 1305.
Rudolf was presented in 1306 as a rival claimant to the Bohemian throne against
Henry of Carinthia. Albert had Rudolf married to Elisabeth Richeza of Poland,
widow of Wenceslas II of Bohemia (1278–1305) and in 1306 occupied Prague to
place Rudolf on the Czech throne.
As some Czech nobles continued to hold out for Henry of Carinthia, Rudolf
besieged the rebel fortress of Horadovice, but fell ill of dysentery and died there in
1307, leaving no children. The Czech nobles then restored Henry of Carinthia as
king in return for a charter of privileges.
