Treaty of Roskilde

28 February 1658

The Treaty of Roskilde was a peace treaty between Denmark–Norway and Sweden, signed after the Swedish king Charles X Gustav had led his army across the frozen waters of the Danish straits, the Little Belt and the Great Belt, an extraordinary winter march that took the Danes by surprise. Faced with an invasion of the main Danish islands, King Frederick III had to accept harsh terms. Denmark gave up the provinces of Scania, Halland, Blekinge and Bohuslän, as well as Bornholm and the Norwegian region of Trøndelag. The treaty made Sweden a power on both sides of the Sound, but the Swedish king soon broke the peace, and the later Treaty of Copenhagen returned Bornholm and Trøndelag.
