|Bishop of Liege|
|Died||1121, Liège, Belgium|
|Venerated in||Roman Catholic Church|
Frederick was Bishop of Liege, succeeding Bishop Alexander, who was forced to stand down after being charged with acts of simony, 1119. As a result the newly appointed Bishop Frederick suffered open animosity from Alexander’s supporters. It is believed that Frederick was poisoned by the count of Louvain, and suffered death in 1121.
