The Folklands (Folklanden) are the name for the original Swedish provinces of Tiundaland, Attundaland, Fjärdhundraland, and Roden (Roslagen) which in the 1296 united to form the modern province of Uppland. They were originally united by electing a common king who administered the sacrifices at Uppsala and who was the commander of the leidang during wars. It is not known when they united for the first time, but already in 98 A.D., Tacitus described the Suiones as a powerful tribe.
