Генрих Лев
In 1152 Frederick I enfeoffed Henry the Lion with the Goslar "Reichsvogtei". In 1158 the emperor gave the citizens of the Goslar the "Kaiserforst" or "Imperial Forest". In 1167 Goslar was besieged unsuccessfully by Henry the Lion. In 1173 in Goslar Frederick I rejected a request by Henry the Lion for the lordship of the town in return for his allegiance in the Italian campaign. Goslar and Rammelsberg remained a pawn in the conflict between the cousins until Henry the Lion was proscribed. In the ensuing war Goslar was shocked in 1180 from the siege by Henry the Lion from the emperor. Henry had the smelting works and mines destroyed, so the mining came to a standstill until 1209.
