Wichmann von Seeburg
archbishop of Magdeburg
Wichmann von Seeburg (c. 1115 – 25 August 1192) was Bishop of Naumburg from 1150 until 1154 and Archbishop of Magdeburg from 1154 until his death. He became the first Magdeburg prince-archbishop in 1180
Life
Wichmann was the second son of the Saxon count Gero of Seeburg (d. 1122) and his wife Matilda, a daughter of the Wettin count Thimo the Brave. He studied theology at the University of Paris before becoming a canon in Halberstadt. Throughout his long ecclesiastical career, he was a loyal supporter of the Hohenstaufen emperor Frederick Barbarossa against Pope Alexander III and an implacable military leader against the emperor's foes in the northeast, especially the Welf duke Henry the Lion.
Wichmann was elected Bishop of Naumburg-Zeitz in 1149 and ordained the next year. He made large donations to the monasteries of Pforta and Zeitz. A regular guest at the court of King Conrad III of Germany, he was quickly appointed to the Archdiocese of Magdeburg by Conrad's nephew, the newly crowned King Frederick Barbarossa in 1152. Wichmann initially had to overcome the resistance by Pope Eugene III and his successor Anastasius IV; nevertheless, he immediately endeavoured to extend his diocese and its economy, and actively promoted trade within the cities. In 1157, he allied with the Ascanian margrave Albert the Bear to re-conquer and Germanise the cities of Brandenburg and Jüterbog, whose vicinity he conquered and colonised with Flemish settlers (cf.

Why this record matters
The subject matters to the general reference register because the source frames it as archbishop of Magdeburg. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 9, 2025. The linked authority identifier is Q316703. VIAF identifies the subject as 71273940. The Library of Congress control number is nr94024875. 3 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1115, 1192, 1150 and 1154.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
