Robert of Trier

Robert, also spelled Ruotbert or Rotbert (died 19 May 956), was the archbishop of Trier from 931 until his death. He played a leading role in the politics of both Germany and France, and especially of the Lotharingian territory in between. He was a patron of scholars and writers and a reformer of monasteries.

If Robert was the canonical age of thirty when elected bishop, he would have been born in 901 or earlier. This is most likely, since he was already the chancellor of the see of Trier under his predecessor, Rudgar. (In 938 he granted a lifetime precaria to his predecessor's niece, Ada, and her two sons.) Robert was originally from the Batavian region, perhaps a member of the Saxon nobility. His brother, Ansfried I, was said to have been the count of fifteen counties, including Toxandria. They were related to the Unrochinger family. In older literature, they were sometimes taken to be brothers of Matilda of Ringelheim, wife of King Henry I of Germany, but this has been proven false. According to the Chronicle of Bishop Thietmar of Merseburg, Robert personally educated his nephew, Ansfried II, in law and theology.

Robert's predecessaro, Rudgar, died on 27 January 931 and Robert became archbishop probably towards the end of the year. He owed his elevation to the influence of King Henry, and shortly afterwards was appointed archchancellor of Lotharingia, a post also held by Rudgar. On 1 June 932, jointly with Archbishops Unni of Hamburg and Hildebert of Mainz, he presided over the synod of Erfurt, a synod of all the bishops of Germany outside of Bavaria. This synod decided to stop paying tribute to Hungary. On 7 August 936, Robert and Archbishops Wigfried of Cologne and Hildebert of Mainz jointly crowned and consecrated Henry's successor, Otto I, in the palatine chapel at Aachen.
