Establishment
The USK was established alongside NATO as a subset of NATO in the late '50s. However, the Union had actually (as a union that had the nations monarchs under a common monarch) existed from the late 1500's to the reformation into the NATO subset version. the USK consisted of Denmark, Iceland, Sweden, Norway and Finland until the Soviet/Warsaw Union annexed Finland and the Bordering parts of Norway, ending Finnish membership. However NATO and the USK still work closely together despite NATO taking little to no action on the Communist annexation of Finland.
