The incumbent patriarchs of Grado and Aquileia, Enrico Dandolo and Ulrich of Treffen respectively, solemnly end the centuries-old conflict between the two churches regarding the metropolitan jurisdictions over the Istrian bishoprics: the patriarch of Grado renounces the metropolitan pretensions of his church, the treasury that Patriarch Poppo took from Grado, and the possessions in Marsano, Aquileia, Zèmole and Marano Lagunare, but receives the spiritual jurisdiction over the parishes Latisana and San Fior, together with the quarter of the tithes and the annual income of up to seventy pounds of Veronese coins.
