the name of a number of dynasties descended from the Oldenburgs, a family of German counts. From 1448 to 1863 representatives of the House of Oldenburg ruled in Denmark, where Christian I was the first king of the dynasty. They also ruled in the two other countries of the Kalmar Union, Norway and Sweden. In Norway they were in power from 1450 to 1814, and in Sweden from 1457 to 1523, except for one interval. They also ruled Schleswig-Holstein from 1460 to 1863. One of the collateral lines of the Oldenburgs was the family Gottorp. The Glücksburg dynasty traces its lineage, through collateral lines, back to the Oldenburgs.
