Sweden proper (Swedish: Egentliga Sverige) is a term used to distinguish those territories that were fully integrated into the Kingdom of Sweden, as opposed to the dominions and possessions of, or states in union with, Sweden. Only the estates of the realm of Sweden proper were represented in the Riksdag of the Estates. Skåne, Halland, Blekinge, and Bohuslän, formerly parts of Denmark and Norway, came under the Swedish Crown by the Treaty of Roskilde in 1658, but it was not until 1719 that they were fully integrated and became part of Sweden proper.
