Reginald III of Burgundy

Reginald III (c. 1093–1148), son of Count Stephen I, held Mâcon jointly with his brother William IV from 1102 and became Count of Burgundy in 1127 after his cousin William III was murdered.

He rebelled against Emperor Conrad III, but was defeated by the duke of Zähringen and lost all his lands east of the Jura. His stand earned him the nickname franc-compte, free count, from which Franche-Comté takes its name. He died in 1148, leaving a young daughter, Beatrice. She married Emperor Frederick Barbarossa in 1156.
