While the marshland and its bogs had to be drained, the higher geestland cores of the islands were in turn mostly barren and needed fertilisation before a proper agriculture could be established.

In these floods entire islands were destroyed and a great part of North Frisian language was torn apart in linguistical and political terms.

During this time of German-Danish conflicts, a North Frisian identity was propagated by people such as Christian Feddersen (1786-1874) who simultaneously denounced nationalist tendencies.

While not designed according to heraldic rules, the shield contains a Frisian eagle on the right side and on the left there is a golden crown in blue above a black kettle in a red field.

The eagle has been interpreted as a symbol of the Frisian freedom granted by the Holy Roman emperor, the crown represents the Danish kings who ruled the area until the mid 19th century.

Also the motto which may be represented in the various dialects of the North Frisian language and always translates to "Rather dead than slave" is seen as originating from Feddersen's views.

After the Second Schleswig War, when anti-Danish tendencies came up, this motto and also the eagle were re-attributed to a German identity and chronicler C. P. Hansen from Sylt invented the legend that the pot was reminiscent of Frisian women who contributed in a battle against the Danes.

North Frisia is seen to be a model location for community wind energy, leading the way for other regions, especially in southern Germany.

Bruus is played in the hinterland of Husum in the villages of Schwesing, Oster-Ohrstedt and Treia where regular tournaments are held.
