Duke Otto of Lotharingia

  General Notes:

Count Palatine of Lotharingia (1034\endash 1045), then Duke of Swabia (1045\endash 1047), and all the while Count in Deutz and Auelgau (1025\endash 1047). He was the son of Ezzo and Matilda (a daughter of the Emperor Otto II),[1] and a member of the Ezzonian dynasty. He was also the protector (Vogt) of Brauweiler Abbey, which had been founded by his parents.

In 1034, Otto's father, the Count Palatine Ezzo, died. As Otto's older brother Liudolf had died in 1031, he succeeded his father as Count Palatine. On 7 April 1045, Henry III, King of Germany and also Duke of Swabia, offered the latter title to Otto. In exchange, Otto gave up the County Palatine, which was bestowed on his cousin Henry. Also, his territories in Kaiserswerth and Duisburg devolved onto the crown.
