Bordering nations of denmark in 1550?

In 1550, Denmark was part of the Kalmar Union, which included Sweden and Norway. At this time, Denmark shared land borders primarily with Norway to the north and had maritime boundaries with Sweden. The union allowed for political and military cohesion among these nations, although tensions and conflicts, particularly with Sweden, were prevalent during this period. Thus, the primary bordering nations of Denmark in 1550 were Norway and Sweden.
