 From the 16th century Plön and Eutin became residences of various branches of the House of Oldenburg.These estates had a thriving cultural scene which, for example, led to Eutin being described at the turn of the 19th century as the "Weimar of the North".Until the middle of the 19th century the area was dominated by Denmark, which initially ran the region as a feoff, but eventually integrated it into the Danish nation-state.
