Halfdan (fl. 782–807)
Halfdan (floruit 782–807) was a leading person among the Danes and the first known Scandinavian to enter Frankish service. Onomastics links him to the Danish royal family since the name "Halfdan" was commonly employed both historically (as attested by the Annales Fuldenses under the year 873) and in the legendary royal lineage. Halfdan was the envoy sent by King Sigfred to the court of the Frankish emperor Charlemagne in 782, as recorded in the Frankish chronicle Annales regni Francorum. An anonymous Saxon poet praising Charlemagne in Latin epic verse mentions Halfdan's commendation to the emperor in the year 807: {| | Northmannorum dux, Alfdeni dictus, / Augusto magno sese comitante caterva / Subdidit, atque fidem studuit firmare perennem. | A leader of the Northmen, called Halfdan, submitted to the great Emperor, accompanied by a host of others and strove to keep lasting faith. |} Although the Saxon poet wrote much later in the century, his poem is generally based on trustworthy sources like the Annales regni Francorum'' and this section is probably derived from a now lost earlier source. There is no record of Halfdan after 807 and he probably died not long thereafter, possibly already old at the time.
