Dietrich III. from Isenberg

from Wikipedia, the free encyclopedia

Dietrich III. von Isenberg († 1226 ) was Bishop of Münster from 1218 to 1226 and Count of Isenburg, from the dynasty of the Counts of Altena (in Westphalia).

Dietrich was in 1196 through the mediation of his uncle, the Archbishop Adolf of Cologne , dean of the influential in Westphalia pin in Soest and followed 1,216 cousin of his father , Count Engelbert von Berg , after his elevation to the archbishopric of Cologne owned by the local Dompropstei.

Probably through the influence of Archbishop Engelbert, Dietrich was elected Bishop of Münster on July 22, 1218. His only brief reign was not without significance for Munster . The episcopal authority in Friesland was re-established and the development of the urban system was given further impetus in the monastery itself, for example by granting Bocholt city ​​rights . With Bernard von der Lippe , Bishop of Selburg, he consecrated the church of the Marienfeld Monastery founded by the latter in 1222 . In 1225 he laid the first stone for the construction of the Münster Cathedral , which, begun by Bishop Hermann II, had stalled under Bishop Otto .

Dietrich's participation in the conspiracy of Westphalian bishops and dynasts against Archbishop Engelbert of Cologne, the result of which was the murder of the archbishop by Dietrich's older brother, Count Friedrich von Isenberg on November 7, 1225, brought about his overthrow. Dietrich, as well as his younger brother Engelbert , chosen bishop of Osnabrück , accused of complicity, demanded that the papal legate Cardinal Konrad von Porto, who was just present on the Lower Rhine, hear the indictment in order to be able to purge himself of the same. The brothers appeared at the meeting called for this purpose by the cardinal in Liege on February 2, 1226 , but after prolonged tumultuous negotiations were unable to pass off the accusations. Bishop Dietrich seemed to be primarily responsible for the outrage; his ministerials were particularly involved in the execution of the murder. The cardinal suspended the brothers and referred them to Rome for further negotiations. The bishops went there, accompanied by their brother Friedrich, Engelbert's murderer, without being able to mitigate their fate. The Pope's verdict was dismissal. Dietrich's death occurred on the return journey from Rome in 1226, probably on July 18th.
