Dominicus Contarenus, dux Venetiarum (1043–1071)

Following the Synod of Rome, convened to resolve the recently rekindled conflict between the patriarchs of Aquileia and Grado, Pope Benedict IX writes to Urso, the patriarch of Grado, informing him of the Synod’s decision to support the cause of his church against the Aquileian Patriarch Poppo, who had recently launched a second military invasion of Grado before his untimely death; the pope confirms the metropolitan status together with the ecclesiastical and secular jurisdictions of the Patriarchate of Grado, dubbed “New Aquileia” for the very first time in an authentic papal document.

Doge Domenico Selvo confirms the donation of various tributes and incomes to the Patriarchate of Grado, originally donated by his predecessor Doge Domenico I Contarini.
