With the accession of young Charles XI of Sweden, his regents begin negotiations to end the Second Northern War.

Regent
In a monarchy, a regent is a person appointed to execute the office of the monarch temporarily. Regencies may arise for a number of reasons, including the monarch being a minor, ill, absent from the country, or otherwise unavailable. A regent may also be appointed in cases where the throne is vacant, or the identity of the legitimate monarch is disputed.
Northern War of 1655–1660
The Northern War of 1655–1660 was fought between Sweden and the Polish–Lithuanian Commonwealth, with participation at different times by Russia, Brandenburg-Prussia, the Habsburg monarchy, and Denmark–Norway. It ended with the treaties of Copenhagen and Oliva in 1660.
