Heinrich von Siegburg

Heinrich von Siegburg was a twelfth century Bishop of Poznań in Poland, he was little known for his career or episcopal work but was active under the rule of Bolesław III Wrymouth.

A German, his home monastery was Michaelsberg Abbey, Siegburg, where he was for a time chaplain to Anno II, Archbishop of Cologne.

The appointment of a German bishop signifies the influence of the Holy Roman Empire and its clergy on the Polish Church, a reflection of Poland's integration into the broader Latin Christian world.. Heinrich von Siegburg played a role in introducing Western ecclesiastical reforms and practices into Poland during a time of cultural transformation.

His connections to Archbishop Anno II and the Michaelsberg Abbey provided him with a rich background in reformist theology and monastic traditions.

According to Gerard Labuda he is the "abbot" in the Life of Saint Henry who was familiar with Otto of Bamberg.
