was founded by Ezzo, Count Palatine of Lotharingia. •
Hermann I,
Count Palatine of Lotharingia. •
Ezzo, Count Palatine of Lotharingia (1015–1034) was one of the most important figures of the Rhenish history of his time. According to the
Brauweiler chronicle, he failed to succeed to the monarchy after the death of emperor
Otto III (983–1002) in a rivalry with duke
Henry II of Bavaria (1002–1024). The succession war between Ezzo and Henry II continued for over ten years. The two men came to an agreement after a battle at
Odernheim in 1011.
Kaiserswerth,
Duisburg and the surrounding imperial territories were granted as a fief to Ezzo for renouncing the throne (after 1016). •
Otto I, Count Palatine of Lotharingia (1035–1045) and Duke of
Swabia (1045–1047). In 1045, after a successful campaign against the rebel count of Flanders, the margrave of Valenciennes and Ename, Otto received the duchy of Swabia, in exchange however for the cities of
Kaiserswerth and
Duisburg, which went back to the crown. •
Heinrich I, Count Palatine of Lotharingia (1045–1060, †1061), son of Count
Hezzelin I (1020–1033). •
Hermann II, Count Palatine of Lotharingia (1064–1085), Count of the Ruhrgau, Zulpichgau and Brabant. His territorial power was importantly reduced by his guardian,
Anno II, Archbishop of Cologne. Hermann is assumed to be the last of the Ezzonids. After his death at Dalhem on September 20, 1085, the
Palatinate of Lotharingia was suspended. His widow remarried the first count palatine of the Rhine, Henry of Laach. The Ezzonid line probably survived in the counts of
Limburg Stirum, who are believed to descend from
Adolf I of Lotharingia, youngest son of
Hermann I. == Other illustrious Ezzonids ==
