Adalgar

Blessed Adalgar was the third archbishop of Hamburg-⁠Bremen, from 888 until his repose on 9 May 909. He is venerated by the Orthodox and the Roman Catholic Church; the Orthodox calendar commemorates him on 9 May, while Wikipedia gives 29 April.

When Rimbert was appointed in 865 to succeed Saint Ansgar in the see of Hamburg, the abbot of the Benedictine abbey of Corvey gave him his brother Adalgar as a companion, then a deacon. Toward the end of Rimbert's life Adalgar was consecrated bishop to assist him, and he succeeded him in the archbishopric on 11 June 888. In the latter half of his rule, age and infirmity made it necessary for him to have a coadjutor, Hoger, another monk of Corvey; later five neighbouring bishops were charged to assist him in his metropolitan duties.

Adalgar lived in troubled times. Arnulf's victory over the Normans in 891 brought relief to his diocese, and under Louis the Child (900 to 911) it suffered less from Hungarian raids than the lands to the south and east. Still, the general confusion limited his activity, and he was able to do very little in the northern kingdoms that were part of his mission. There were also new disputes over the relation of Bremen to the archiepiscopal see of Cologne. Pope Formosus decided that Bremen should be united to Hamburg as long as the latter had no suffragan sees, but should revert to Cologne when any were erected. Little is known of his personality; those who wrote of him show a man of some force, perhaps not strong enough for the hard times.
