Political event
With the Acts of Commonwealth the Northern Duchies signed their dependence on each other, practically forming the Arnish Commonwealth, which was soon turned into the Kingdom of the Arnmark. The Dukes of Arnholm, Dee, Esten, Forden, Hafn, Marsh and Norden signed the Acts in the Temple of Vildehall in Arnheim and acknowledged that their survival as an independent state depended on their collaboration.
