Paulinus II of Aquileia was a priest, theologian, poet, and one of the most eminent scholars of the Carolingian Renaissance. From 787 to his death, he was the Patriarch of Aquileia in what is now northeastern Italy. He participated in a number of synods which opposed Spanish Adoptionism and promoted both reforms and the adoption of the Filioque into the Nicene Creed. In addition, Paulinus arranged for the peaceful Christianisation of the Avars and the alpine Slavs in the territory of the Aquileian patriarchate. For this, he is also known as the apostle of the Slovenes.
