Liemar (unknown – 16 May 1101, in Bremen) was archbishop of Hamburg-Bremen from 1072 to 1101, and an important figure of the early Investiture Contest.
He was a supporter of Emperor Henry IV from 1073.[1] In 1074 the papal legates Gerald of Ostia and Hubert of Palestrina put pressure on him to hold a local synod; he resisted, was suspended, and by 1075 his views against papal interference with bishops had hardened.[2] In 1080, he attended the Synod of Brixen that condemned Pope Gregory VII.[3] With Benno II of Osnabrück he commissioned the anti-papal polemic of Wido of Osnabrück around 1085.[4] Liemar was one of many bishops who was irked by Gregory VII's encroachment of episcopal autonomy. In a letter to Bishop Hezilo of Hildesheim, Liemar complained that Gregory VII was ordering his bishops about 'as though they were his bailiffs'.[5]
