Coupland finds the contents of the letters particularly revealing. Rorik had apparently been granted control over Dorestad twice and well before his conversion to Christianity in the early 860s. Hincmar and Hunger having to convince Rorik not to give refuge to a declared enemy of Charles the Bald would mean Rorik enjoyed a "measure of political independence" from the various courts of the Carolingian dynasty at the time. Coupland notes that his contemporary Sedulius Scottus calls Rorik a King (Latin:Rex). Though noting that the reference has alternatively been interpreted to mean another contemporary ruler, Rhodri the Great of the Kingdom of Gwynedd. A hagiography of Adalbert of Egmond, written in the late 10th century, mentions a miracle of the saint in the time of "Roric the barbarian king" (Latin:Roricus barbarorum rex)
