The first danegeld ever raised was collected in Frisia in 810. In that year a Danish fleet of some two hundred vessels landed in Frisia, harassing first all the coastal islands and then the mainland before defeating the Frisians in three battles. The victorious Danes then demanded a large tribute from the conquered. Soon after, a report was sent to Charlemagne, then at Aachen contemplating a campaign against the Danish king, Godfred, stating that the Frisians had already collected through taxation and paid a sum of one hundred pounds of silver. These events are recorded in the "Annales regni Francorum" and the "Vita Karoli Magni", both works of Charlemagne's court historian, Einhard, and in the separate "Reichsannalen" called the "Annales Mettenses" and the "Annales Maximiniani", as well as the work of the so-called "Poeta Saxo". The total sum paid out is unknown, but it was without doubt raised through taxes, as Einhard in his "Vita" explicitly says: "And the victorious Danes imposed a tribute on the vanquished, by means of taxes one hundred pounds of silver from the Frisians is already released" ("Danosque victores tributum victis inposuisse, et vectigalis nomine centum libras argenti a Frisionibus iam esse solutas").
