The Copenhagen Peace ( dated. Freden i København ) - a peace treaty between Denmark and Sweden concluded on May 27 ( June 6 ), 1660 in Copenhagen . With the signing of the Oliwski Peace and the Copenhagen Peace, the Northern War of 1655-1660 ended. This treaty was a relatively small addition to the world of Roskilde , which established the borders of Denmark, Sweden and Norway, which have remained almost unchanged to this day. In addition to the treaty in Roskilde , part of its territory was returned to Denmark - Bornholm Island in the Baltic Sea and the northern region of Trøndelag . In addition, the provision on the non-admission of non-Baltic states to the Baltic Sea was abolished.
