On 7 November 921, the Treaty of Bonn, the text of which calls itself a "pact of friendship" (amicitia), was signed between Charles III of France and Henry I of Germany in a minimalist ceremony aboard a ship in the middle of the Rhine not far from Bonn.[1][2] The use of the river, which was the border between their two kingdoms, as a neutral territory had extensive Carolingian precedents and was also used in classical antiquity and in contemporary Anglo-Saxon England.[3]
