Henry the Proud, a member of the House of Welf, was Duke of Bavaria from 1126 to 1138 and Duke of Saxony as well as Margrave of Tuscany and Duke of Spoleto from 1137 until his death. In 1138 he was a candidate for the election as King of the Romans but was defeated by Conrad of Hohenstaufen.

The House of Welf is a European dynasty that has included many German and British monarchs from the 11th to 20th century and Emperor Ivan VI of Russia in the 18th century. The originally Franconian family from the Meuse-Moselle area was closely related to the imperial family of the Carolingians.
