Burchard Grelle
Burchard Grelle (c. 1260–1344) was Archbishop of Bremen from 1327 until his death. Born into a Bremen citizen family, he studied at the University of Paris and represented the archdiocese at the papal court before Pope John XXII appointed him to Bremen in 1327 after the death of Archbishop Jens Grand.
One of only two commoners ever to hold the see, Grelle maintained unusually good relations between the city and the archbishopric, and politically aligned himself with the Curia against Emperor Louis IV.
