EZZO, or EHRENFRIED (c. 954–1024)  , count palatine in Lorraine, was the son of a certain Hermann (d. c . ,000), also a count palatine in Lorraine who had possessions in the neighbourhood of Bonn . Having married Matilda (d . 1025), a daughter of the emperor Otto II., Ezzo came to the front during the reign of his brother-in-law, the emperor Otto III . (983–1002); his power was increased owing to the liberal grant of lands in Thuringia and Franconia which he received with his wife, and some time later his position as count palatine was recognized as an hereditary dignity . Otto's successor, the emperor Henry II., was less friendly towards the powerful count palatine, though there was no serious trouble between them until rot I ; but some disturbances in Lorraine quickly compelled the emperor to come to terms, and the assistance of Ezzo was purchased by a gift of lands . Henceforward the relations between Henry and his vassal appear to have been satisfactory . Very little is known about Ezzo's later life, but we are told that he died at a great age at Saalfeld on the 21st of March 1024 . He left three sons, among them being Hermann, who was archbishop of Cologne from 1036 to zo56, and Otto, who was for a short time duke of Swabia; and seven daughters, six of whom became abbesses . Ezzo founded a monastery at Brauweiler near Cologne, the place where his marriage had been celebrated . This was dedicated in 1028 by Piligrim, archbishop of Cologne, and here both Ezzo and his wife were buried .
