Radboud was born around the middle of the 9th century from a noble Frankish family near Namur. His mother was of Frisian origin and a descendant of the Frisian king Radboud. Radboud began his studies under the care of his maternal uncle Gunthar, Archbishop of Cologne from 850 until his deposition in 863. After that Radboud continued his studies at the court school of the Western Frankish king Charles the Bald, whose chaplain he became. After Charles's death, he presumably became a Benedictine monk in the famous Saint-Martin convent of Tours. In 899 Radboud was elected bishop of the diocese of Utrecht with the permission of Emperor Arnulf of Carinthia. Because Utrecht was destroyed by the Normans, he did not live there but in Deventer in the Oversticht, where one of his predecessors had settled. As bishop, Radboud was the most important representative of East Frankish authority in the northern Netherlands. In 911, however, the Duchy of Lorraine, in which the diocese of Utrecht was located, came to the western Frankish kingdom. Radboud then seems to have wavered between loyalty to his old king or loyalty and connection with the new monarch. His most ancient biographical description criticizes him for the use of bishops in the East Frankish government, but this criticism may be the responsibility of the author. Around 914/915 he traveled to Rome where he presented a further unknown conflict with Count Meginhard of Hamaland to Pope John X ; After having heard Radboud and representatives of Meginhard, the pope found a settlement. Radboud made preparations to take the seat in Utrecht again. To do so, he drew up a list of all the possessions of the diocese before the expulsion by the Normans. Radboud died in Ootmarsum in 917 before these plans could be executed. He had appointed his successor, Balderik, himself.
Writings
A number of smaller writings are attributed to Radboud, but there are doubts about his authorship. Most of the writings are saints' lives, some in prose, others in verses. He described the life of the Anglo-Saxon missionariesBoniface, Suitbert and Lebuïnus, as well as St. Amalberga and Bishop Saint Servatius of Maastricht.
Veneration
He was buried in the Lebuin Church of Deventer. Several sources, including historian Johan Picardt, indicate that his intestines have been buried in the church in Nijenstede. During the Middle Ages, the veneration of Saint Radboud remained limited to the diocese of Utrecht. His feast day is 29 November.
