He was a leading supporter of the Holy Roman Emperor Henry IV in the Investiture Controversy, and of antipope Clement III.

A priest in Halberstadt, Wezilo owed his promotion to the support of Henry IV. In 1085 he negotiated on behalf of the emperor with the papal legate, the future Pope Urban II, and in the same year he was convicted of simony and excommunicated by the pro-papal Synod of Quedlinburg.<ref>{{cite book |author=Patricia Skinner |chapter=From Pisa to the Patriarchate: Chapters in the Life of (Arch)bishop Daibert |editor=Patricia Skinner |title=Challenging the Boundaries of Medieval History: The Legacy of Timothy Reuter |publisher=Brepols |year=2009 |page=158 |isbn=978-2-503-52359-0 |author-link=Patricia Skinner (historian) }}</ref>
