In the summer of 782, Charlemagne led his armed forces to the sources of the
Lippe River, staying there for some time. On this occasion he received envoys from Sigfred, although the details of the negotiations are not disclosed. Shortly after, Widukind left his Nordic refuge and returned to Saxony where he successfully egged the population to rebel against the Frankish king. He then led the Saxon resistance until 785 when he finally submitted to Charlemagne. For several years, there is no mention of the Danish king, but in 798 Charlemagne sent one of his trustees, Godeskalk, on a diplomatic mission to Sigfred. On his return, Godeskalk was slain by the rebellious Saxons living to the north-east of the
Elbe. When the Franks put down the rebellion they were helped by the prince of the
Obotrites,
Drozko, who would later on be dealt with by Sigfred's successor
Gudfred. Poems by the
Lombard literati
Peter of Pisa and
Paulus Diaconus convey a very negative image of Sigfred. Peter wrote that Charlemagne had let him choose between being fettered, imprisoned, or sent to convert Sigfred. In a poetic reply, Paulus castigated the Danish king as a wild beast who ruled over other wild animals; an uncouth pagan who would nevertheless be unable to stand up against the mighty Frankish ruler. If he dared molest Peter and his entourage and refuse Christianisation, he would quickly be led before Charlemagne's throne in fetters, abandoned by
Odin (Waten) and
Thor (Thonar). It is interesting that the characterization is similar to that accorded to
Ongendus, one of Sigfred's predecessors in the early 8th century. The poems also indicate that the Danes had started to draw some attention from the Carolingian elite by this time. The reign of Sigfred had ended by 804 when another ruler,
Gudfred, is mentioned in the Frankish annals. ==Place in early Danish history==
