The Treaty of Copenhagen (

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.[1]

Opening positions

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).[2] 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.

Frederick argued to his Dutch allies that Swedish control of Scania would present an eternal lingering threat to Copenhagen, and proposed a Danish-Dutch alliance to retake Scania. Frederick had the support of

Cardinal Jules Mazarin threatened a French invasion of the Netherlands if it were to assist Denmark against Sweden.[3]

When learning of Charles' death in February 1660, Frederick immediately proclaimed the Treaty of Roskilde null and void. This caused great alarm to the Swedish mediators, but their French and English counterparts assured them that if Sweden were to yield their claim to Trøndelag but otherwise stick by the terms of Roskilde, France and England would assure a treaty under those conditions. Denmark insisted on the return of the Scanian lands, with the support of Brandenburg, Austria and Poland, but this time the Dutch did not agree with Denmark. On 8 March 1660, admiral Michiel de Ruyter and his Dutch fleet were ordered to leave the harbour of Landskrona, where he had bottled up the Swedish fleet. Frederick yielded, and the negotiations began in earnest on 24 March.[4]

Negotiations

The most contentious point was regarding the control of the island of Bornholm. The people of Bornholm had risen against their Swedish occupants, and killed the Swedish commander, Johan Printzensköld. They now feared retribution, were the island to remain in Swedish hands. Frederick had given his word of honour to protect his faithful subjects to the utmost; he kept his promise by demanding the return of Bornholm to Denmark despite the threats of Sweden and the negotiating powers. It was then suggested that Denmark would provide compensation by ceding several estates held by Danish noble families in Scania to the crown of Sweden.[5]

At this point, however, the negotiations started to derail as the mediating countries' representatives became involved in intrigues that weren't in the interests of their client states. Exasperated by the slow progress of the negotiations, Hannibal Sehested suggested that negotiations should proceed directly between Denmark and Sweden. The suggestion was accepted by the Swedes, and in a few days the conditions of the treaty were agreed upon.[6]
