Amalarius of Trier

Amalhar or Amalarius Fortunatus (c.775 – c.850) was the third Archbishop of Trier from 809 until 814.

Amalhar was a pupil of Alcuin of York. In 809, Charlemagne appointed him to the see of Trier and in 813 he was sent as the chief Frankish ambassador to the court of Michael I Rhangabes at Constantinople. On Charlemagne's death in 814, Amalhar resigned his see. Nevertheless he remained a partisan of Louis the Pious throughout the tumult of his reign.

In 831, Amalhar travelled to Rome to meet Pope Gregory IV and arrange a new German liturgy. In 835, he replaced Agobard at the Synod of Diedenhofen and implemented liturgical reforms. In 838, on the accusation of heresy, the Synod of Quierzy banned some of his works. He died around ten years later at Metz.

His writings form a good portion of our current documentation of the ninth century liturgies of the Western Church.
