Gerard, Duke of Lorraine

Gerard of Alsace (c. 1030–1070), the second son of the count of Metz, received Metz in 1047 when his elder brother Adalbert became Duke of Upper Lorraine under Emperor Henry III. After Adalbert fell fighting the deposed duke Godfrey III the next year, Henry invested Gerard with Lorraine.

Rebels imprisoned him, but Bishop Bruno of Toul, later Pope Leo IX, freed him in 1049. Gerard remained loyal to the imperial dynasty.

In 1053 he fought at the disastrous Battle of Civitate against the Normans. He founded the castle of Prény, the seed of Nancy, and died in 1070 suppressing a revolt.
