Мальмёхус
Malmöhus County was part of Skåne province which was controlled by Denmark until 1658. In 1657, Denmark declared war on Sweden, while Sweden was at war with Russia, Poland, and Austria. Swedish forces were sent immediately from Poland to Denmark. Denmark was defeated which required the transfer of Skåne, Halland, Blekinge and Bohuslän provinces to Sweden under the Treaty of Roskilde. Denmark attempted to regain the lost provinces until 1710, but was unsuccessful.
