efused to acknowledge the new king, Conrad III deprived him of all his territories,
giving the Duchy of Saxony to Albert the Bear and that of Bavaria to Leopold IV,
Margrave of Austria. In 1147, Conrad heard Bernard of Clairvaux preach the Second
Crusade at Speyer, and he agreed to join King Louis VII of France in a great
expedition to the Holy Land which failed.
Conrad's brother Duke Frederick II died in 1147, and was succeeded in Swabia by
his son, Duke Frederick III (known as Frederick Barbarossa). When King Conrad
III died without adult heir in 1152, Frederick also succeeded him, taking both
German royal and imperial titles.
In 1089, Frederick married Agnes of Germany, daughter of Henry IV, Holy Roman
Emperor. They had several sons and daughters, amongst whom were:
Frederick II of Swabia (1090–1147), the father of Frederick Barbarossa
Conrad III, King of Germany (1093–1152)
FREDRICK II, DUKE OF SWABIA
Frederick II (1090 – 6 April 1147), called the One-
Eyed, was the second Hohenstaufen duke of Swabia
from 1105. He was the eldest son of Frederick I and
Agnes.
He succeeded his father in 1105. In 1121 he married
Judith of Bavaria, a member of the powerful House of
Guelph. On the death of Emperor Henry V, his uncle,
Frederick stood for election as King of the Romans
with the support of his younger brother Conrad, duke
of Franconia and several houses. However, he lost this
election of 1125 to Lothar III, crowned Emperor later in 1133.
A conflict erupted between Frederick and his supporters, and Lothar. Encouraged
by Adalbert of Mainz, who loathed the supporters of the late Emperor Henry V,
Lothar besieged Nuremberg in 1127. Frederick relieved the siege of Nuremberg in
1127 and occupied Speyer in 1128. The attempt of Henry the Proud, duke of
Bavaria, to capture Frederick during negotiations failed (1129). However,
afterwards supporters of Lothar won a number of victories both in Germany and in
Italy. Speyer (1129), Nuremberg (1130) and Ulm (1134) were captured and in
October 1134 Frederick submitted to the emperor. In 1135 both Frederick and
Conrad were finally reconciled with Lothar. After Lothar's death (1137) and election
