Pisa Becomes a Metropolitan Archdiocese

Pope Urban II elevated the Diocese of Pisa to a metropolitan archdiocese, which signified an important development in the Catholic Church's structure in Italy. This elevation allowed Pisa to have greater ecclesiastical authority over surrounding dioceses, enhancing its influence in religious and political matters. The new status was part of Pope Urban II's broader efforts to strengthen the Church's organization and address the challenges faced in the region during this period.
