Origins & Early Life

The Treaty of Copenhagen (Danish: Freden i København, Swedish: Freden i Köpenhamn) was signed on 27 May 1660, and marked the conclusion of the Second Northern War between the Swedish Empire and the alliance of Denmark–Norway and the Polish–Lithuanian Commonwealth. This treaty was a smaller follow-up treaty to that of the Treaty of Roskilde, which decisively delineated the mutually recognized boundaries of Denmark, Sweden, and Norway; boundaries which are almost exactly the same to this day.

Career & Major Achievements

Charles X of Sweden would not accept any other outcome than Sweden's receipt of Akershus county, in exchange for the return of Trøndelag and Bornholm to Denmark–Norway; Frederick III of Denmark on the other hand refused to abide by the terms of the Treaty of Roskilde, instead wanting to revert to the conditions of the Second Treaty of Brömsebro (1645).

Enduring Legacy & Impact

Both kings were stubborn, and had to depend on the mediating powers, France and England on the Swedish side, and the Dutch Republic on the Danish side, to bring about a treaty.
