Theodoric II, Duke of Lorraine

Theodoric II the Valiant (died 1115) succeeded his father Gerard as Duke of Upper Lorraine in 1070. A rival claimant contested the succession, but Theodoric won election by the nobles, granted the County of Vaudémont to his brother to bind his family, and was confirmed by Emperor Henry IV.

The duke remained loyal to the emperors, campaigning against the Saxons between 1070 and 1078 and opposing the reforming popes.

In 1095 he took the cross for the First Crusade but withdrew through ill health, sending his vassals east instead. Afterward he took little part in imperial affairs, and he died on 30 December 1115.
