Treaty of Copenhagen (1660)

1660 · 17th century · Part of the Second Northern War

The Treaty of Copenhagen was signed on 27 May 1660 between Denmark-Norway and Sweden, ending the war that Charles X Gustav had renewed in 1658. Concluded after his death, it returned Bornholm and Trøndelag to Denmark-Norway, while Scania, Halland, Blekinge and Bohuslän remained Swedish as agreed at Roskilde. It fixed a frontier between Denmark and Sweden that has lasted to the present.
