The place name Vogtland (formerly also known as "Voigtland", "terra advocatorum") originates in the rule of the Vogts in this region from the eleventh to the sixteenth century A.D., specifically in reference to the Vogts of Weida, Gera and Plauen. In the 12th century, Kaiser Barbarossa appointed the first Vogts as administrators of his imperial forest areas in the East to facilitate his rule. Their headquarters was the Osterburg at Weida, thus giving it the reputation as the cradle of the Vogtland. Among the privileges of the Vogts were the endowment over minerals still unextracted from the ground "(Bergregal)" and the entitlement to regulating mint and coinage affairs "(Münzregal)", which were both handed down to them by Kaiser Frederick II in 1232.
