Unni

Saint Unni was Archbishop of Hamburg-⁠Bremen from 916 to 936 and a missionary in Scandinavia. He was a monk at New Corvey in Germany when he was chosen bishop, in 917 by some sources and in 916 by others.

He worked to enlighten Sweden and Denmark, continuing the work of Saint Ansgar. He reposed on 17 September 936 at Birka in Sweden, where he had gone as a missionary. According to Adam of Bremen, his body was buried at Birka and his head in Bremen Cathedral. When the altar was taken down in 1840, a leaden plate with his name was found there. After Ansgar and Rimbert, Unni is revered as the third Apostle of the North.

He is commemorated on 17 September, as a saint of the undivided Church, by the New Calendar.
