• Education: say 965, Augsburg, Bavaria, Germany; He was sent as a child to be educated by Bishop Ulrich of Augsburg (episcopate 923–973), a relative of his mother. Nothing more is known about his youth.
• Land/House: 996; At the death of his father in 996, Herman's rich allodial property was shared between his sons. Ezzo received lands in Cochem on the Mosel river, in Maifeld, the Flamersheimer Wald and estates around Tomburg Castle near Rheinbach, as well as half the usufruct of Villewaldin. About the same time, he must have received the Palatinate and previous countal rights, as he is referred as count in the Auelgau in 1015 and as Count Palatine in the Bonngau in 1020. He also received the county of Ruhrgau with tutelage of Essen Abbey.
• Miscellaneous: 1002; Unsuccessful candidate to the imperial throne upon the death of Emperor Otto III in 1002, his relation with the new Ottonian king Henry II was immediately very tensed. Henry disputed Ezzo's ownership of territories, that he defended as his wife's inheritance of late Otto III. The conflict dragged on for years and reached its peak in 1011. Facing disturbances in Lotharingia, and in need for Ezzo's military support, Henry was forced to come to terms. Ezzo's victory led the king to make concessions and to a complete transformation of its policy. He reconciled with Ezzo, recognized its rights of inheritance and gave him the royal territories of Kaiserswerth, Duisburg as well as Saalfeld in Thuringia for renouncing to the throne. He also associated the Ezzonid dynasty to his Eastern policies, and mediated the marriage of Ezzo's daughter Richeza with the heir to the Polish throne Mieszko II Lambert.
