Renaud III, Count of Burgundy

From Wikipedia, the free encyclopedia

Renaud III (c. 1093 – 1148), son of Stephen I of Mâcon (Tête-hardi) and Beatrix of Lorraine, was the count of Burgundy between 1127 and 1148. Previously, he had been the count of Mâcon since his father's death in 1102, with his brother, William of Vienne.

About 1130, he married Agatha (d. April 1147), daughter of Simon I, duke of Lorraine. He proclaimed independence from the Holy Roman Emperor Lothair III, but was defeated by King Conrad III of Germany and forced to relinquish all his lands east of the Jura. The name of the region Franche-Comté is derived from his title, franc-compte, meaning "free count".

His sole daughter Beatrice (c.1145 – 15 November 1184) became countess of Burgundy on her father's death and married the Emperor Frederick Barbarossa in 1156.
