The Treaty of Frederiksborg (Danish: Frederiksborgfreden) was a treaty signed at Frederiksborg Castle, Zealand, on 3 July 1720[1] (14 July 1720 according to the Gregorian calendar), ending the Great Northern War between Denmark–Norway and Sweden.
The Danish-Swedish conflict began with Danish attack in 1700 but Sweden forced a peace the same year, while continuing to fight Russia.
Denmark rejoined the war in 1709 in a campaign to regain their lost provinces; Scania, Blekinge, and Halland.
[2] Sweden paid 600,000 Riksdaler in damages, broke her alliance with Holstein and forfeited her right to duty-free passage of Öresund.
Denmark also gained full control over Schleswig, while Danish-held areas of Swedish Pomerania were returned to Sweden.
