'Otto William' (962 – 21 September 1026) was a son of Adalbert, King of Italy, and Gerberga of Mâcon.
His mother gave him what would be the Free County of Burgundy around Dôle in 982. Otto also inherited the duchy of Burgundy on the other side of the Saône in 1002 from his stepfather Otto Henry the Great. The duchy then corresponded to the diocese of Besançon in the Holy Roman Empire. He was also Count of Mâcon in France.
Burgundy was annexed to the crown of France by King Robert II in 1004. Determined to be sovereign ruler of his own lands, Otto revolted against the Emperor Henry II in 1016. This was after Rudolph III of Burgundy, the last king of that realm, had done homage to Henry at Strasbourg making him his guard and heir. On Otto's death, the Free County fell under the suzerainty of the German emperors.
