After its victories in the Thirty Years' War, Sweden reached the height of its power during the Second Northern War, when its primary adversary, Denmark–Norway, was neutralized by the Treaty of Roskilde in 1658. Charles XI of Sweden consolidated the empire. But a decline began with his son, Charles XII. After initial Swedish victories, Charles secured the empire for some time in the Peace of Travendal in 1700 and the Treaty of Altranstädt in 1706. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Era: Great Northern War Communications: wkpPpV2PEG ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Kung: MalarkeyHunter Drottning: JolieMannerhiem Crown Prince: ReiKomugi Riks & Överstemarskalk: N/A Hovmarskalk: ElmersGlueStew
