Hermann II, Archbishop of Cologne

Herman II (c. 995 – 11 February 1056), a member of the Ezzonid dynasty, was Archbishop of Cologne from 1036 until his death.

He was the son of the Lotharingian Count Palatine Ezzo (955–1043) and his wife Matilda of Germany, Countess Palatine of Lotharingia(979–1025), a daughter of Emperor Otto II and his consort Theophanu. He was a member of the Ezzonian dynasty. Herman's younger brother Otto became Duke of Swabia in 1045; among his sisters were Richeza, who married the Polish King Mieszko II Lambert, and Theophanu, Abbess of Essen.

Pope Benedict IX elevated him to the College of Cardinals around 1036, at the same time the Salian Emperor Conrad II appointed him Archbishop and granted important privileges to the Church in Cologne. Herman accompanied Conrad on his Italian campaign and remained loyal to his successor Henry III. In 1049 he received Pope Leo IX in Cologne and in 1051 consecrated Goslar Cathedral. His claritas generis allowed him to baptise and crown the emperor's newborn son Henry IV, a privilege that was disputed by Archbishop of Luitpold I of Mainz. Herman also supported the emperor during the revolt led by his own nephew Duke Conrad I of Bavaria.
